Keg King KS1 Keg Scale Review!

Ever had your keg kick empty right in the middle of a pour? Or wondered if that CO₂ tank is about to give up the ghost? I have – and it’s a real pain in the ass! Enter the Keg King KegMaster KS1 Bluetooth keg scale, a nifty gadget that promises to tell you exactly how much beer (or gas) you’ve got left without any lifting or guessing. I’ve been putting one through its paces in my kegerator, and here’s what I found.

There are few things worse than pouring a beer and hearing that dreaded hiss — the keg’s blown, and you didn’t see it coming. Or, even worse, your CO₂ tank taps out mid-session. That’s where the Keg King KegMaster KS1 Keg Scale comes in. It’s a simple, smart way to keep tabs on your kegs without lifting, guessing, or getting caught empty-handed.

What It Does

The KS1 is a Bluetooth-enabled scale that slips under your keg (or CO₂ bottle) and beams live weight and volume data to the KegMaster app. It’s small, tough, and built for the fridge. Think of it as giving your kegerator x-ray vision — you’ll always know how much beer or gas you’ve got left.

Easy Fit for the Homebrewer

At just 25 mm tall, the KS1 sits neatly under a Corny keg and handles weights up to 60 kg. The recessed center ring also works perfectly with CO₂ cylinders. Bluetooth Low Energy keeps the connection strong through kegerator walls, without messing around with Wi-Fi or logins. Better yet, the app supports multiple scales at once — so you can line up all your kegs in the “My Taps” view and see what’s left in each.

Accuracy on Point

To test it, I tared an empty keg and added water in increments all the way up to 19 L. Every step was bang on. The app even converts weight to volume based on the gravity you set. Add in a built-in temp sensor, and you’ve got accurate readings you can trust every time.

Foolproof Setup & Smooth Use

Setup is a breeze: charge with USB-C, power on, open the app, and the scale appears instantly. Add a tap, select keg size, tare it empty, and you’re good to go. Day to day, the app is clean and intuitive — customize units, set gravities, and name your taps so you know exactly what’s on pour.

The battery lasts months between charges, and topping up with USB-C is painless. Downsides? A hidden “refresh” button that isn’t labelled, partial-fill setup that could be smoother, and 50 L kegs overhanging the edges. With 19 L Corny kegs, though, it’s a perfect fit.

Price vs. Value

At around AU$99, the KS1 is excellent value compared to older smart keg monitors. Multi-buy discounts make it even more affordable for multi-tap setups. For less than the cost of a couple of brew days, you get peace of mind, fewer surprises, and a tool that genuinely makes kegging easier.

Final Pour?

The KS1 is one of those upgrades that feels small but makes a big difference. It’s accurate, simple, and fairly priced — exactly what you want in a gadget that lives in your kegerator. If you’re tired of guesswork and want real-time insight into your beer and gas, the KS1 is well worth a spot under your kegs.

Verdict: Highly recommended for any homebrewer running kegs.
