"We tested it and after a year the yeast was still good. The beer still tasted fine. We wouldn't normally keep the same yeast for that period of time but it shows that you can do without cleaning for, say, six months," he says.
"My system is closed so once you put the yeast in, it stays there. You do not need to touch it. The more you touch the yeast, the greater risk of getting an infection which is deadly in a brewery."
Heiliger says that his device takes up about 30 square meters, whereas traditional systems can be up to 300 square meters in size.
