My son and a friend of his (both 17) are very intrigued by the brewing process. When it came time to bottle tonight they both showed up to help and learn. We spent the whole time talking about brewing and they had a ton of questions, starting with, "I have to wash my hands before we start, right?" The best question of the evening was from the friend who wanted to know "When do you add the alcohol?" so we had to discuss fermentation 101. A rather pleasant bottling experience for a change, I filled and they capped.
