What better way to reward yourself after a busy day than a nice cold draught beer? However, since the outbreak of COVID-19, bars have been regarded as high risk areas and have often been closed, so enjoying a draft beer has not been easy. To help solve the problem, a number of manufacturers have introduced beer machines for use at home, so you can enjoy a refreshing draught-like brew whenever you like.

Principle of Beer Machine

1. Ultrasonic vibration

As the name suggests, ultrasound transforms the natural carbonic acid in beer into a fine uniform foam by vibrating thousands of times per second to enhance the aroma, flavour and taste. Most home-use beer machines use this principle and are powered by a USB or battery for easy operation.

2. Carbon dioxide

Carbon dioxide reacts with water to form carbonated bubbles. It also slows down oxidation and maintains the quality of the beer. Commercial beer frothing machines often use carbon dioxide or nitrogen to inject gas into the beer to add flavour. A number of home-use beer machines work under the same principle. However, these models require regular replacement of the carbon dioxide cylinders. This could cause over-carbonation and is a higher threshold for home users.

Types of Home-use Beer Machine

1. Tabletop type

Larger, tabletop type machines can be used with cans and small bottles which is a unique advantage. Some models have built-in ice packs to keep the beer cold for hours, making them ideal for home parties.

2. Can spout type

Can spout beer machines are small and portable which makes them ideal for parties, barbecues, picnics and camping trips. In addition, they can be installed on top of canned beers and are suitable for beer lovers who want to enjoy draught beer alone.

3. Handheld type

Handheld beer machines are easy to operate. You simply dip the probe into the beer to create foam. These machines are suitable for use with all kinds of receptacles. With a similar shape to a stirrer, they are ideal for people who love beer and making cocktails.

Shopping Tips

1. Compatible with packaging

Depending on the model, the beer machine can be used on different packaging sizes. For example, a tabletop beer machine can be used for both cans and small bottles of beer while a can model can only be used for canned beer. Check the compatibility before purchasing beer and beverages.

2. Insulation feature

Insulation requires space for ice packs, so not all beer machines have the capacity to keep beer cold. Users who prefer ice cold beer should check the model description before purchasing a beer machine.

3. Portability

A wireless beer machine is not only easy to carry, it has no restrictions on where it can be placed. Check the weight and size if you are going for portability.

4. Easy to clean

A beer machine needs to be cleaned after use. Choose a model that is easy to disassemble and wash ensures good hygiene, so the taste of the beer will not be affected later.
