My uncle once had a home brew beer kit that had instructions with as many steps as making a cake from scratch. You had to mix up ingredients in one jug and then put it in another to ferment and then carbonate in another. It was a complex process. WilliamsWarn has made the process of brewing beer at home a snap with the Personal Brewery.
The downside is that ease of use for this WilliamsWarn Personal Brewery makes it very expensive, the thing sells for about $4,500. You have to be serious about home brewing to spend that much loot. The device takes all the steps you need to mix and ferment the beer into the single stainless steel contraption.
You mix, remove sediment, and clarify the beer along with fermenting it in one place. Once the beer is ready to drink, you can carbonate it, chill it, and dispense the beer from the machine too. It takes about a week to make a batch of beer.
