My nephew and a buddy of his want to learn about all-grain brewing, so on the 22nd, I'm hosting my first "real" teaching brewday.
Nephew made his first batch 2 weeks ago, a Mr. Beer kit his wife bought him, but he's already looking into jumping all-grain.
I'll make sure we stay fairly focused on what we're doing, and if there's any imbibing, it'll be moderate at most, so they actually learn something (I hope).
I almost didn't agree to do this; the last time I tried to host a brewday, for my brother and a friend of his ~5-6 yrs back, it went from my brother saying "I want to brew how you do" to him and his buddy just hanging out and drinking my beer.
They lost a lot of interest once they saw that all-grain does require some actual work, not just sitting around drinking and watching.
For those of you who've hosted a teaching brewday, any advice or suggestions?
