Immersion Chillers vs. Plate Chillers vs. Counterflow Chillers

Crafting your own beer is a thrilling journey, but every brewer knows that achieving the perfect temperature during the chilling process is crucial for a successful batch. When it comes to chilling wort, homebrewers have several options at their disposal, each with its own set of advantages and drawbacks. In this guide, we'll explore three popular chilling methods: immersion chillers, plate chillers, and counterflow chillers, highlighting their pros and cons, putting their cooling power to the test with an experiment, and telling you which is best (in our modest opinion) for homebrewing beer!

‍

‍

Introducing the Contestants!

Immersion Chillers:

Pros:

1. Simple Design: Immersion chillers are perhaps the most straightforward option. They consist of a coiled copper or stainless steel tube that is submerged directly into the wort.
2. Ease of Use: Operating an immersion chiller requires minimal setup and can be easily used by brewers of all experience levels.
3. Affordability: Compared to other chilling methods, immersion chillers are typically more budget-friendly, making them an attractive option for beginners or those on a tight budget.

Cons:

1. Slower Cooling: Typically immersion chillers can take longer to cool the wort compared to other methods, especially if the tap water temperature is high.
2. Limited Efficiency: Since immersion chillers rely solely on the surrounding liquid (usually tap water) for cooling, their efficiency can be affected by factors such as water temperature and flow rate.
3. Sanitation Concerns: Ensuring the cleanliness of the immersion chiller can be challenging, as it is exposed to the wort throughout the chilling process.

Plate Chillers:

Pros:

1. Efficiency: Plate chillers are highly efficient at rapidly reducing the temperature of wort due to their large surface area and counterflow design.
2. Compact Size: Plate chillers are typically smaller and more portable than other options, making them ideal for brewers with limited space.
3. Temperature Control: Plate chillers allow for precise temperature control, enabling brewers to achieve their desired pitching temperature quickly and consistently.

Cons:

1. Cleaning Challenges: Plate chillers have intricate internal channels that can be difficult to clean thoroughly, increasing the risk of contamination and off-flavors if not maintained properly.
2. Potential Clogging: The narrow channels of plate chillers are prone to clogging from hop debris and other particulates present in the wort, requiring regular maintenance and cleaning to prevent issues.
3. Higher Cost: Plate chillers tend to be more expensive upfront compared to immersion chillers, which may deter budget-conscious brewers.

Counterflow Chillers:

Pros:

1. Efficient Cooling: Counterflow chillers combine the rapid cooling of plate chillers with the simplicity of immersion chillers, offering excellent efficiency and performance.
2. Minimal Wort Exposure: Unlike immersion chillers, counterflow chillers minimize the exposure of wort to potential contaminants, enhancing the overall quality and stability of the beer.
3. Versatility: Counterflow chillers can handle varying flow rates and temperatures, providing brewers with greater flexibility and control over the chilling process.

Cons:

1. Complex Design: Counterflow chillers have a more intricate design compared to immersion chillers, which may require additional setup and maintenance.
2. Risk of Clogging: Similar to plate chillers, counterflow chillers can be susceptible to clogging from hop debris and other solids, necessitating regular cleaning and maintenance.
3. Higher Cost: Counterflow chillers are typically more expensive than immersion chillers, making them a significant investment for homebrewers, particularly those on a tight budget.

The Experiment

To assess the cooling power of each unit we filled a brewzilla with 45L (11.9 gal) of water and heated it to 80°C (176°F), from here we gave each chiller 10 minutes to cool down the water as much as it could (obviously separately, and reheating the water between each test). Before taking a temperature reading (using both the base thermometer of the brewzilla and a separate thermometer) we gave the water a big mix using a mash paddle and allowed it to whirlpool for 10 seconds before measuring the temp, this helped to ensure an equal distribution of heat throughout the water, so that we weren't measuring hot or cold spots in the liquid that had yet to reach homeostasis.

‍

The Results

This may seem a rudimentary experiment, but often in science it is best to use Occam's razor to find an an answer, the problem-solving principle that recommends searching for explanations constructed with the smallest possible set of elements, and the same logic can be applied to finding the best way to construct an experiment. The least amount of variables possible to still find a definitive answer will yield the clearest results! Make sense? So, with all that said lets take a look at the results below!

‍

‍

I was pretty surprised! I entirely expected the plate chiller to come out on top, but in actuality the immersion chiller managed to cool the water 5°C (10.1%) more than the plate chiller, and a whopping 12.2°C (21.4%) more than the counterflow chiller!

‍

But Does Size Matter!?

Now with all this said and done, yes it is important to concede size does matter (sorry gents!), the more surface area contact with the liquid being cooled that a chiller has, the greater cooling power it will posses, so whilst this experiment is great at telling us which is "best" at cooling between these very commonly available homebrewing chillers, it must be remembered that if you used a much smaller immersion chiller, it would not have any where near the cooling power of the chiller we were using in this experiment. So if you take anything away from this at all, please just make sure you use a chiller that is of an appropriate size to your brewing system! and when in doubt, bigger is better!

So Which Chiller is The BEST?

When it comes down to it, this is entirely a personal preference for each brewer, each chilling method has its own set of advantages and drawbacks, and the best choice ultimately depends on your brewing setup, preferences, and budget. Immersion chillers offer simplicity and affordability, while plate chillers excel in efficiency and temperature control. Counterflow chillers strike a balance between the two, offering excellent performance with minimal wort exposure. Whichever option you choose, proper maintenance and sanitation are essential to ensure consistent and high-quality brews. Cheers to your next successful batch!

‍

Which is my Favourite?

So whilst I cant say which is the definitive best, I will say which is my personal favourite to use. The Plate Chiller! There is a reason it is the most commonly used design amongst commercial brewers! As long as its used correctly and you have adequate filtering before wort enters, you should have minimal issues with blockages, its incredibly compact which makes it the most space efficient of the 3, and you can clean the bejesus out of the thing! By using powerful caustics and acids you can make it an incredibly sterile environment before your fresh wort enters, making it my personal favorite chiller. Despite the fact it only took out the silver metal in my little experiment, I believe its pro's out whey its small performance deficient against my immersion chiller, so it still holds the gold in my heart!

Guide to Beer Brewing Water Chemistry

Water chemistry is often seen as the final frontier for a lot of home-brewers, sort of like the last thing you can master after understanding all the different elements of the brewing process, and can truly make an average beer a good beer, and a good beer a great beer! But for some reason something about water chemistry seems a little daunting and scary to learn and understand, but there are great tools and calculators (such as brewfather) that calculate salt additions for you, and here we have written up this quick guide to give you an idea of the basics so you can start dipping your toes into the world of brewing chemistry!

‍

‍

1. Water Sources:

Choose a water source with characteristics suitable for brewing. If using tap water, be aware of its mineral content, as it varies by location. You may need to adjust your water profile to match the beer style you're brewing.  

Test your water to determine its baseline characteristics, including pH, hardness, alkalinity, and mineral content. This information is crucial for making precise adjustments in subsequent steps. If you are using tap water you can generally request a water chemistry report from your local council.

Tap Water:

Pros:

• Convenient and readily available.
• Contains minerals that can contribute to the brewing process.

Cons:

• Inconsistent mineral content based on location.
• May require testing and adjustments to meet brewing needs.

RO (Reverse Osmosis) Water:

Pros:

• Highly customizable, as it starts with a blank slate.
• Allows precise control over mineral content.

Cons:

• Stripped of minerals, which must be added back for brewing.
• Initial setup cost for an RO system.

Spring Water:

Pros:

• Contains natural minerals that can enhance flavor.
• Often free from chlorine or chloramine.

Cons:

• Variability in mineral content based on the source.
• Potential for contamination, requiring testing.

Well Water:

Pros:

• Unique mineral profiles can impart distinct flavors.
• Generally free from chlorine or chloramine.

Cons:

• Requires testing due to variable mineral content.
• Risk of contamination, especially in unregulated wells.

Distilled Water:

Pros:

• Completely devoid of minerals, providing a clean slate.
• Ideal for starting from scratch in mineral adjustments.

Cons:

• Lacks beneficial minerals, necessitating careful additions.
• May lack some elements important for yeast health.

2. pH Adjustment:

• General pH Range: The pH of your brewing water should ideally be between 5.2 and 5.6
• Acid Addition: Use food-grade acids like lactic acid or phosphoric acid to lower pH if needed.
• Alkalinity Reduction: Reduce alkalinity with acid or dilution for light-colored beers.

3. Calcium and Magnesium:

• Calcium (Ca): Essential for enzyme activity during mashing. Aim for 50-150 ppm.
• Magnesium (Mg): Contributes to yeast health. Target 5-20 ppm.

‍

4. Sulfate and Chloride:

Sulfate (SO4): Enhances hop bitterness and dryness. Adjust based on beer style (e.g., high for hoppy beers).

• Typically you want to keep this in the ranges of 50-150 ppm for enhanced hop bitterness depending on the beer style

Chloride (Cl): Enhances malt sweetness and fullness. Adjust based on beer style (e.g., high for malty beers).

• Typically you want to keep this in the ranges of 0-250 ppm for increased malt sweetness

Sulfate to Chloride Ratios:

The balance between sulfate and chloride in your brewing water can significantly impact the perception of bitterness, sweetness, and overall beer character. Consider the following sulfate to chloride ratios for different beer profiles:

Malty Beers and New England IPA's (NEIPA):

1. Ratio: 0.5 (Sulfate:Chloride)
2. Description: A higher chloride content contributes to a fuller mouthfeel and enhances malt sweetness, which complements malty beer styles and hazy IPAs like NEIPAs.

Balanced Beer Profile:

1. Ratio: 1:1 (Sulfate:Chloride)
2. Description: A balanced sulfate to chloride ratio is suitable for a wide range of beer styles, providing a harmonious interplay between hop bitterness and malt sweetness. This is a versatile choice for many classic beer styles.

Hop-Forward Beers (e.g., West Coast IPA):

1. Ratio: 2:1 (Sulfate:Chloride)
2. Description: A higher sulfate content accentuates hop bitterness and dryness, providing a crisp and refreshing character. This ratio is well-suited for hop-forward styles like the classic West Coast IPA, where a clean bitterness and fresh hop character are desired.

Important Considerations:

• Impact on Perception: The sulfate to chloride ratio affects the perceived balance between hop bitterness and malt sweetness. Experiment within these ratios to achieve the desired flavor profile for your specific beer style.
• Adjustment Method: Use brewing salts such as gypsum (calcium sulfate) for sulfate additions and calcium chloride for chloride additions. Gradually adjust the levels while monitoring the impact on flavor.
• Style Guidelines: Refer to style guidelines for specific recommendations on sulfate to chloride ratios, especially when brewing to match a particular beer style.

Understanding and manipulating sulfate to chloride ratios allows you to tailor your water chemistry to the unique requirements of different beer styles, enhancing the overall quality and enjoyment of your homebrewed beers.

5. Sodium:

• Sodium (Na): Usually kept low (below 50 ppm) to avoid off-flavors. Adjust based on beer style.

6. Hardness and Alkalinity:

• Hardness: Reflects the concentration of calcium and magnesium. Aim for a balanced profile.
• Alkalinity: Affects mash pH stability. Adjust to control pH during mashing.

7. Mineral Additions:

• Use brewing salts like gypsum, calcium chloride, Epsom salt & Slaked Lime to adjust specific ions in your water.
• Follow water chemistry calculators or software to determine precise additions, such as brewfather.

8. Batch or Continuous Adjustment:

• Batch Adjustment: Add minerals to the entire brewing water volume.
• Continuous Adjustment: Add minerals to the mash or boil kettle separately for more control.

9. Record Keeping:

Keep detailed records of water adjustments, brewing process, and the resulting beer. This helps you refine your process over time.

10. Experimentation:

• Don’t be afraid to experiment with different water profiles for various beer styles.
• Small adjustments can have a significant impact, so start with conservative changes.

11. Monitoring and Adaptation:

Regularly test and monitor your water characteristics, and adjust your process accordingly. Water chemistry can vary, so adapt to changes in your water source.

By paying attention to water chemistry, you can fine-tune your brewing process and produce beers with well-balanced flavors that align with your intended style. Experiment, learn from each batch, and refine your approach to create exceptional homebrewed beer.

How to Make a Yeast Starter!

Here's our guide to how and why you should make yeast starters for your brews, but if you'd also like to learn how to culture yeast from previous batches check out our 2 part series on culturing yeast. Part one is here for you below!

Why should I make a yeast starter?

Yeast starter's are a super valuable tool in the brewing (and baking) world that helps ensure a strong, healthy yeast population, faster fermentation, and improved overall quality and consistency in your final product. It's particularly beneficial for more challenging recipes and high-gravity beers and top prevent the chance of other wild yeasts, bacteria or even fungi from infecting your batch!

More than that here's a few great reasons to make a start for your beer.

1. Ensure Adequate Yeast Population: A yeast starter helps you increase the population of active and healthy yeast cells before adding them to your main batch. This is especially important when brewing high-alcohol or complex beers where a larger yeast population is needed to ferment the sugars effectively.
   ‍
2. Faster Fermentation: With a well-prepared yeast starter, the fermentation process can begin more quickly. This reduces the lag time between pitching the yeast and the start of fermentation in your primary batch, which can help prevent potential contamination issues.
   ‍
3. Reduced Risk of Off-Flavors: A yeast starter allows the yeast to undergo a growth phase, promoting a healthy yeast population. Healthy yeast is less likely to produce unwanted off-flavors or aromas, contributing to a cleaner, more consistent final product.
   ‍
4. Consistency: Making a yeast starter ensures consistency in your brewing or baking process. By using a known quantity of yeast cells, you can more accurately predict the fermentation time and results.
   ‍
5. Improved Attenuation: Yeast starters can help improve the yeast's ability to ferment the available sugars to completion, resulting in a beer with better attenuation and a drier finish, or bread with a better rise and crumb structure.
   ‍
6. Yeast Viability: Yeast starters allow you to assess the viability of your yeast before pitching it into your main batch. If the yeast does not ferment in the starter, you can replace it with fresh yeast rather than risking your entire batch.
   ‍
7. Economical / Stretching the Budget!: Making a yeast starter from a smaller initial packet of yeast can save you money in the long run, as you can stretch your yeast supply across multiple batches.
   ‍
8. Adaptation to Brewing Goals: A yeast starter gives you the flexibility to tailor the yeast's characteristics to your specific brewing goals. You can adjust the starter's size, temperature, and other factors to influence yeast growth and flavor profiles.
   ‍
9. Better Flavor Profiles: For certain beer styles, like lagers and Belgian ales, yeast starters can help promote the development of desirable flavor compounds and esters that contribute to the style's unique character.
   ‍
10. Worry-Free Pitching: Using a yeast starter can give you peace of mind, knowing that you've taken steps to ensure a healthy and active yeast population in your batch, reducing the risk of stuck fermentations or other fermentation issues.

So How do we make one?

Step by Step Process

1. DME (dry malt extract) at a ratio of approx. 100g per 1L water (3.5 oz per 33 fluid ounces) for gravity of approx. 1.040 some unfermented wort kept cold and sanitary from a previous brew day
   ‍
2. 70g of table sugar per 1L water (2.5 oz per 33 fluid ounces) – however, it is best to use malt sugar (wort / DME) whenever possible to reduce the chance of shocking the yeast with a different food source from starter to wort pitching
   ‍
3. if you are using DME (dried malt extract) it is best to boil the starter for 10-15 minutes to kill any microbes that may be present in the powder from the factory or packaging
4. after boiling the starter cool it down quickly in an ice/water bath until it reaches approximately 25°C (77°F)
   ‍
5. once the starter is cooled to pitching temperature add your yeast
   ‍
6. cover the vessel with some tin foil, or a foam bung/stopper, you don't want the vessel to be airtight, it still needs oxygen to promote healthy yeast growth, it just needs to be covered to prevent bugs or other things in the air from infecting your starter!
   ‍
7. If you have a stir plate, set the starter on it a day before you brew with the stir plate mixing the start with a light whirlpool (it doesn't need to be too aggressive!) to help keep yeast active and oxygen getting pooled into the starter
   ‍
8. if you dont have a stir plate just give the jar/vessel a gentle swirl every now and then over the next 24 hours to keep the yeast active and in suspension

Don't want to make a starter? Try yeast re-hydration

To simply rehydrate yeast (not a starter) Add yeast to approx. 10 times as much room temperature water as the weight of the yeast e.g. 10g yeast in 100 ml water (0.35 oz yeast in 3.5 fluid ounces water)

Beer Off-Flavours Cheat Sheet!

‍

Why Does my beer taste bad?

That is the million dollar question and one of the most googled searches from homebrewers! Well there could be a lot of causes, but there is always common factor, something has gone wrong and its made an "off-flavour!" so here we have compiled our off-flavours cheat sheet to help you self diagnose what is going wrong with your latest homebrew! It also helps if you take heaps of notes when you brew so you can go back later to figure out what mightve gone wrong!

Step 1

Try and figure out what flavour / aroma it is that you are getting in your beer that doesnt seem right.

Step 2

Go through the list of off flavours below to identify the potential causes for that compound being formed in your beer, and use the process of elimination to identify what went wrong with your batch so that you can fix it for next time!

‍

‍

No. 1 Acetaldehyde

Cause

• Produced during the early stages of fermentation when yeast is in its logarithmic phase and rapidly multiplying·
• it can also be caused by too much or too little dissolved oxygen being present in the beer during early fermentation·
• can also be produced by beer sitting on yeast cake for too long, when yeast health is poor they can burst open and release copious amounts of the chemical into the beer

Flavour / Aroma

• Fresh Paint
• Unripe green apples
• Freshly cut pumpkin
• Faintly cidery

How to prevent / Fix it

• Keep yeast healthy – don’t stress them out e.g.
• Pitch a sufficient quantity of yeast (don’t under or over pitch)
• Do not under or over aerate wort (no more than 1 min with a paint mixer is good)
• Keep temperature steady
• Do not rush fermentation allow it to completely finish
• Dump trub and yeast when needed, don’t let it sit on yeast cake for too long

No. 2 Alcoholic

Cause

• Higher weight fusel alcohols produced from fermentation when yeast is under too much stress
• Hot fermentation, typically in excess of 27 °C / 80 °F (unless it’s a yeast designed for hot fermentation e.g. Kviek)
• Very high gravity wort, especially when large amounts of sucrose or unrefined sugar is added

Flavour / Aroma

• Hot prickly alcohol, similar to the taste and smell of a cheap tequila

How to prevent / Fix it

• Keep fermentation within the appropriate temperature range for your yeast
• When adding adjuncts to brewing try not to increase the gravity too much with unrefined sugar
• Use a yeast starter where possible to build a healthy yeast culture and acclimatise yeast to wort before pitching

No. 3 Diacetyl

Cause

• A compound that is naturally formed during the fermentation process from diacetyl precursors, however in excess quantities it becomes apparent as an off flavour

Flavour / Aroma

• Butter
• Butterscotch
• Buttery microwave popcorn

How to prevent / Fix it

• Keep yeast happy and healthy by
• Not over or under aerating wort before pitching (no more than 1 min with a paint mixer is good)
• Ferment in the appropriate temperature range for your wort
• Do not rush fermentation
• Pitch a sufficient quantity of yeast (don’t under or over pitch)
• You can also help clean up diacetyl before bottling/canning/kegging beer by raising the temperature of your fermentation by 2-3 degrees for 2-3 days before packaging, this helps the yeast eat the last remaining sugars and absorb the diacetyl back into their cell walls

No. 4 Astringency

Cause

• Polyphenols (tannins) which react with the proteins in your mouth forming a “haze” coating your tongue, these polyphenols can come from:
• Over hopping with too many low alpha acid hops
• Over dry hopping
• Over sparging and/or sparging with water that’s too hot (above 80 °C / 176 °F)
• High mash pH and/or too

Flavour / Aroma

• Similar to bitterness
• Powdery / dry feeling
• Similar to sucking on a used black tea bag

How to prevent / Fix it

• Keep dry hop quantities to a reasonable level and reduce contact time between hops and fermenting beer (no more than 2-3 days) this can be done by trub dumping, or using a hop sock to remove hops after a set time
• Keep sparge temp to about 78-80 °C / 172-176 °F
• Stop sparging after sparge water is showing a gravity of 1.01
• Especially for stouts and dark beers check pH isn’t too high

No. 5 Estery / Fruitiness  

Cause

• Either Isoamyl Acetate or Ethyl Acetate (depending on the fermentation) that is desirable in some beer styles but not all, resulting from excess Acetyle-Co A which is a compound yeast produce to convert nutrients (like fatty acids and sterols) into cellular building blocks during the logarithmic growth phase

Flavour / Aroma

• Banana
• Canned Fruit salad
• Nail polish remover (aroma)

How to prevent / Fix it

• Reduce factors that encourage excessive yeast growth and stress
• Ferment on the cooler side of the recommended temperature range for your yeast
• Aerate wort sufficiently before pitching yeast
• Pitch a sufficient quantity of yeast (don’t under or over pitch)

‍

No. 6 Medicinal

Cause

• Can be from either
• Use of Chlorine or Iodine based cleaning chemicals that are not thoroughly rinsed out of equipment

Or

• Yeast being used too many times – resulting in a strain that has changed and mutated over usage, as well as likely been infected by wild yeasts, bacteria or fungi

Flavour / Aroma

• Band-aids (plastic strips for cuts an wounds
• Hot plastic
• Cloves (cooking spice)

How to prevent / Fix it

• Thoroughly rinse and clean out equipment after using chlorine or iodine based chemicals
• Check that your city water isn’t too high in chlorine, if so use a known water source that doesn’t (e.g. RO water (reverse osmosis water))
• Don’t re-use yeast for too many generations (no more than 10!)

So... What is it?

Beer, one of the oldest and most beloved beverages in the world, has a rich and fascinating history that stretches back thousands of years. Its origins can be traced back to the dawn of civilization, and its evolution through history has not only quenched the thirst of countless people but also made significant contributions to science and biotechnology.

Where did it start?

The story of beer begins in ancient Mesopotamia, modern-day Iraq, around 4,000 BCE. The Sumerians, the earliest known civilization in human history, were responsible for the cultivation of barley, a key ingredient in beer production. They discovered that by soaking and fermenting grains, they could create a delightful and intoxicating beverage.

The Sumerians held beer in high regard and even considered it a gift from the gods. They developed an extensive brewing tradition, with evidence of over twenty different types of beer in their culture. Brewing became an integral part of their society, and breweries were established as communal gathering places. Bet you didnt know that when you last poured your favorite frothy!

How did it spread?

As civilization spread, so did the art of brewing. The ancient Egyptians adopted beer brewing techniques from the Sumerians and incorporated their own unique flavors, such as dates and honey. Beer played a prominent role in their religious rituals and daily life, serving as currency and nourishment for laborers.

The knowledge of brewing eventually made its way to ancient Greece and Rome, where beer took a backseat to wine as the preferred alcoholic beverage. However, the Romans recognized the cultural significance of beer and spread its consumption throughout their vast empire. They introduced beer to regions like Gaul (modern-day France) and Germania (Germany), where it would later flourish.

It was in medieval Europe that beer truly began to flourish. Monasteries became centers of brewing excellence, with monks meticulously perfecting the craft. They experimented with different ingredients, brewing techniques, and yeast strains, leading to the development of new beer styles.

In the 13th century, the introduction of hops revolutionized beer production. Hops not only acted as a natural preservative but also imparted bitterness and aroma to the beer. This discovery led to the creation of more stable and flavorful beers, such as the now iconic pale lagers.

With the rise of industrialization and advancements in science during the 18th and 19th centuries, beer production underwent a significant transformation. The invention of the steam engine, refrigeration, and the microscope greatly influenced the brewing process. The understanding of yeast fermentation and the ability to control temperature and quality led to consistent and standardized beers.

In the 19th and 20th centuries, scientific breakthroughs further propelled the beer industry. Louis Pasteur, renowned for his work in microbiology, studied the fermentation process and developed techniques to control and prevent spoilage. His research contributed to the understanding of yeast, bacteria, and the importance of sanitation in brewing.

Beer's contributions to science and biotechnology extend beyond brewing techniques. The study of beer has played a vital role in the development of fields such as microbiology, biochemistry, and genetics. Yeast, a key ingredient in beer production, has been extensively studied and manipulated for various scientific purposes, including the advancement of medicine, biofuels, and industrial processes.

Witches were brewers?

During the medieval period, brewing beer was primarily done by women known as alewives or brewsters. They played a significant role in providing their communities with beer. However, as brewing became more commercialized and male-dominated guilds emerged, female brewers faced challenges. Negative stereotypes associating female brewers with witchcraft arose, fueled by the mysterious and superstitious nature of brewing and the use of medicinal herbs. These myths led to the persecution of women during the witch trials of the 16th and 17th centuries.

It's important to note that these associations were based on societal biases and prejudices of the time. Female brewers have always been integral to brewing and sustaining communities, contributing to the cultural and economic force of beer. Today, efforts are being made to recognize and celebrate the contributions of all brewers, regardless of gender, and to break down barriers in the industry. By understanding the historical context and promoting inclusivity, we can appreciate the art of brewing without perpetuating harmful stereotypes.

Where are we today?

the modern craft beer movement has reshaped the brewing industry by bringing back traditional styles, encouraging experimentation and innovation, fostering community engagement, promoting beer education, and driving economic growth. Craft breweries have revitalized the beer landscape, offering consumers a diverse array of high-quality, flavorful, and locally produced beers. As the movement continues to evolve, it promises to inspire new generations of brewers and beer enthusiasts, pushing the boundaries of what beer and we zymurgists who craft it can achieve.
