Draft beer at home, just like at the pub, with our beer dispensers
The taste of a draught beer is something different compared to that of a canned or bottled one, and you certainly don't have to be an expert to notice it. Those who really know about beer, then, are even less willing to make compromises and dream of tasting it exactly as if they were in the pub, savouring all its taste and creaminess.
How to do it then? Beer culture has made great strides in recent years, both in terms of production and consumption, and today it is possible to buy a beer tap without having to spend a fortune, so as not to give up the pleasure of a perfectly prepared mug at any time, not even at home.
Are you also looking for a table-top beer dispenser to keep in the kitchen, or maybe a more professional model to use for your parties and barbecues with friends? No problem! Klarstein offers you different solutions, all easy to install, with a pleasant and modern design and different capacities, so you can enjoy your favourite drink in all situations.
How does a beer dispenser work?
Technically, a beer pump is an electrical appliance consisting of a housing for the keg, a circuit through which the beer flows from the keg to the tap mouth and a carbon dioxide cartridge which allows the beer to be extracted from the keg at the right pressure and temperature. The device regulates the outflow of beer and the amount of carbon dioxide, ensuring that the beer dispensed is gassed to the right point and that the beer inside keeps its organoleptic properties intact.
The dispenser works with beer stored in kegs, i.e. containers that are used to keep the beer under pressure and can have a variable capacity, from 2 to 5 litres for disposable domestic ones up to 50 for steel ones used in pubs. There is also a gas under pressure - usually carbon dioxide or carbon-nitrogen - in the dispenser, which has the function of pushing the beer inside, allowing it to be dispensed through the taps.
When talking about beer draft machines, the difference between high-end and cheaper models is that in a professional beer dispenser there is a compressor similar to the one fitted in all refrigerators, connected to a cold water tank where the pipes that join the keg to the taps pass. The compressor acts on the pipes, cooling them so that the temperature of the liquid passing through them drops.
This dispensing system has a clear advantage since the pressure allows the carbon dioxide molecules to break down, forming the foam that is so loved by fans of thorns, also making sure that the original flavour of hops and malt is enhanced and the beer is more digestible. In the case of systems for domestic use, on the other hand, no cylinder is used, but a small CO2 refill that has the dual function of cooling and allowing the drink to be dispensed.
The cooling capacity of the beer tap
The quantity of beer and the time it takes to bring it to the temperature suitable for consumption defines the cooling capacity of a beer dispenser. Professional models operate on the principle of instant refrigeration, while those designed for domestic use can be equipped with an integrated cooling system, based on a compressor that lowers and maintains the temperature of the beer at a constant level, thus allowing the best preservation of its organoleptic qualities.
Compressor cooling systems take a few hours to lower the temperature, so the advice is to keep the kegs in the fridge for some time before opening, to pre-cool them. Since each beer has an optimal tasting temperature - for example between 8 and 10 degrees for a Pilsner, between 10 and 14 degrees for a Belgian Ale - a table-top beer tap normally allows you to select the degrees at which the amber nectar should be maintained to maximize its taste.
Storage time of the beer kegs
Properly tapping beer is the main reason for buying a home beer dispenser but once opened, a keg has a limited lifespan, as it is pressurised and therefore subject to a gradual loss of carbon dioxide. For this reason, it is important to choose a beer dispenser equipped with an internal compressor, able to keep constant not only the ideal temperature for consumption but above all the level of pressurisation, which has a crucial impact on the quality of the product.
The ability to store beer inside the keg is therefore important when buying a keg that is expected to be consumed over a long period, and usually, a home beer tap allows you to store an open keg inside for a period of between seven and thirty days.
Some good reasons to buy a home beer dispenser
With a beer tap, you can comfortably enjoy an exquisite cold draft beer at home in sufficient quantity to avoid having to go out to the bar or pub. Its taste will also be exceptional, as draught beer maintains the same consistency and quality from the first to the last glass, unlike canned or bottled beer, which quickly loses its gas.
For the same quantity, beer in kegs is also cheaper than bottles or cans, but using a beer tap will not only save you money and make a clever purchase but also free up valuable space in the fridge: consider, for example, that a 5-litre keg of beer is equivalent to 15 cans. Not to mention the time you save by avoiding having to constantly refill the fridge once you have consumed your first beers if the space you have available is limited.
The last aspect not to be overlooked is the reduced environmental impact, since consuming beer in kegs reduces the consumption of non-recyclable glass bottles and cans, reducing the production of waste. Once finished, you can easily throw the mini keg into the recyclable waste container, or return it to the distributor to start another round.
A beer dispenser is powered by electricity and allows you to cool the beer and keep it at the right temperature for a long time. The best beer dispenser for home brewing has a low energy consumption and a power of about 70W. The various products are also distinguished by the size of the keg they can contain. Beer is usually stored in 2, 3 or 5-litre kegs. Depending on how much you consume, you will have to choose the right amount of beer: it is always better to consume the beer within a few weeks. The standard shape and size of the kegs are usually standard and allow you to choose your favourite beer from the wide selection on the market.
How to operate a domestic beer dispenser
To use the domestic beer tap, simply insert the keg into the appliance by removing the protections, as indicated on the packaging, and secure it to the machine. At this point, the appliance must be connected to electricity, and it will start cooling the keg until it reaches the right temperature - that can be set only on some models. Once reached, the temperature will be kept constant.
After more or less 20-30 minutes, beer should be ready and it will be ready for as many times as desired until the keg is empty. You will notice that only foam comes out of the tap and this means it’s time to replace the keg.
To tap your beer, simply place the mug under the tap and open it with the other hand. The tapping techniques depend on the different styles of beer: German, Belgian or English each has its own precise method. The glass should be placed under the tap of the beer dispenser, which then descends vertically. Tap the beer in 2-3 steps, waiting for the foam to compact itself naturally. When tapped in this way, the beer will contain a correct amount of gas and the foam will remain exclusively on the surface.
