I'm about to try a batch of root beer with my son using champagne yeast and extract. My homebrew shopkeep recommended I use plastic bottles I was wondering if 1/2 liter water bottles worked well, creating individual servings, as we don't have many 2 liter bottles kicking around. The plastic of the water bottle is a little thinner than a 2 liter, but I don't know how significant that might be. Any thoughts?
