I am brewing this weekend (the first batch in a long time) and am kegging it. But I don't have a fridge to keep it cold. I saw something called a Brewcap that will let you pressurize a 2-liter soda bottle. This seems the perfect answer to my problem - I keep the keg in the corner of the basement, and a 2-liter in the fridge. Has anyone used one of these?
