Brewing, also known as zymurgy, is the ancient art of converting
grains, chiefly barley, into
liquor, particularly that most noble of
beverages,
beer. It has been a longtime hobby of mine; my mother bought be a kit when I was a teenager and I've been brewing ever since.
It's pretty easy to do; you just boil your materials, cool and add yeast. Then you wait; the yeast do all the work. And the finished product is superb.
