The advantage of this method is that the carbonation of the beer is preserved since CO2 is the same gas that gives beer its fizz. Hooking up your keg to a CO2-powered dispenser also helps prolong the shelf life of your beer, even after you’ve tapped the keg. Of course, beer needs to be served at the proper temperature. This is usually fridge temperature (around 4C), but it depends on the style. A beer dispenser does this in one of two ways. Unlike a can, however, you can’t just open a keg and pour beer from it. You need to hook it up to a dispensing system. The dispenser pushes beer from the keg and into the tap faucet, using either a CO2 gas canister or gravity. The coupler refers to the part of the beer dispenser that connects to your keg. When you “tap” a beer, it means you hook the coupler to the mouth of the keg.

If you’re importing and tapping American kegs, then you’ll need a D-type coupler. If you fancy a few German lagers straight from the source, then you should seek the M-type. In the UK, the main coupler types are S-Type (also called a Sankey Keg coupler) and the G-Type (or Grundy Keg coupler). Most mainstream brands use either of these two coupler types. For example, Carlsberg and Kronenbourg both use S-Type, while Carling and Tennents use G-Type. A less commonly used coupler is A-Type, which is the coupler type used by Guinness and Hoegaarden. CO2 beer dispensers are for you if you’re after the best draft experience that replicates what you’ll get in a pub. Some draft systems are also visually gorgeous and perfect for your home bar or man cave. Also, if you mostly drink craft beer kegs or brew your own, CO2 dispensers are the only way to tap one.

All in all, the Klarstein Beerkules is one of the best beer dispensers we’ve ever used. It’s a home setup that gives you a pro-level of control over the quality of your pours.

Thermoelectric Technology - Chills beer to as low as 4°C and has a handy precise LED temperature gauge along with being quiet to use. So is it worth getting a Fizzics? The problem is that, because you’re serving from a bottle or can rather than a keg, it can get tedious to serve beer to a larger crowd. In this regard, traditional draught systems still have an advantage. Beer dispensers draw beer out from a keg in one of two ways – through the pull of gravity or the push of carbon dioxide (CO2) gas.At the heart of the Beerkules is its UltraFast Cooling technology, capable of chilling a full keg to serving temps in just under 4 hours. And you can easily adjust the temperature of the beer, from 2 to 12 C, with either manual adjustments or any of the six presets. Are you serving a high alcohol Belgian beer? Crank it up to around 8C to enjoy all the subtle aromas and flavour characteristic of these kinds of brew. The answer is in the Fizzics’s proprietary Micro-Foam technology, developed for over four years with brewers, drinkers, and experts. Essentially, it converts canned or bottled beer into a nitro-style pour by using (believe it or not!) sound waves. What you get is a creamy and smooth beer with enhanced flavour and aroma. IPAs are fruitier and more aromatic, stouts are richer, and Pilsners are crisper. The problem is that there’s more than one type of coupler. In fact, there are several, and which one you use depends on the beer you want to tap and the country you’re living in. This beer dispenser also has a flow regulator near the tap so you can adjust your pour to prevent over-foaming. Pushing the beer is possible with a built-in air compressor, so there’s no need to hook an external CO2 tank.

Now, the good news is that you can easily switch the coupler for some beer dispensers with the one that you need. Before buying a keg, make sure to research online and see which coupler type it uses. However, the Royal Catering dispenser does take longer to chill kegs compared to the Beerkules. It’s also missing a few features like the beer gauge. Some users have also reported that it’s not as user friendly. The size of your beer dispenser pretty much determines how big or small of a keg you can fit into it, and therefore how many servings you can expect. Most home systems accommodate a 5-litre keg, which roughly translates to 10 pints of beer. The Sub is one of the most compact beer dispensers in the UK, with a space footprint that’s smaller than a piece of A4 paper. Because of this, the Sub is an excellent beer dispenser for bringing to parties and gatherings.On top of that, the Big Spender doubles as a regular fridge. You can chill bottles of beer or wine while you’re dispensing draft beer. It’s the perfect all-in-one solution to serving alcohol at your next party. It even has caster wheels for easy hauling around the venue. There’s too much head on every pint we pour, even with the dial on the lowest setting. Why is this? A beer dispenser system starts with a keg of beer. A keg is a self-contained canister pressurized with carbon dioxide (CO2) gas that helps maintain the beer’s carbonation and freshness until serving time. It’s similar to how beer bottles or cans work; in fact, you can look at a keg as nothing more than an oversized beer can.
