My girlfriend and I brewed our first batch of beer this weekend. I'm a computer programmer, and she is a microbiologist. From everything I've read, sanitation is very important. However, she basically told me that the fact we're in an open environment and using tap water means that sanitizing the equipment really doesn't do much good. There is plenty of bacteria in the air, and tap water is anything but clean. As long as the equipment is clean, it's as good as it's going to get. Thoughts?
