The machine reportedly incorporates all the hardware needed for brewing. This includes a stainless steel pressure vessel with carbonation level control, and systems to control factors such as clarification, sediment removal, temperature, and gas dispensation. Last, but certainly not least, it also features a draft dispense mechanism, for pouring out a glass of the chilled “commercial quality” finished product.
Users spend about 90 minutes cleaning and sterilizing the system, and adding supplied ingredients at the beginning of the process. After that, minimal input is required until a week later, at which point 23 liters (6 U.S. gallons) of beer should be ready for drinking. Part of the reason that it’s able to make beer so quickly is the fact that the carbonation and fermentation processes take place simultaneously. The clarification process is also said to take no more than one day.
The WilliamsWarn brewing machine is currently only available in New Zealand, although its makers hope to expand to the Australian and American markets soon. It sells for NZ$5,660 (US$4,577), plus NZ$39.50 (US$32) for the ingredients for each batch of beer.
