Our home brew club is coming over the end of May and we are going to do 45 gallons of Amber. We are trying to get together and brew every other month. So far we did an English Special Bitter, where we all take home 5 gallons and put a different yeast in it. Then we all brought it back to the meeting one month and tasted it. Then we did a sweet stout and we all put some different additive to it. We split our 5 gallon batch and made half a chocolate and half a chocolate with chili in it. We have that meeting at the end of March. Last weekend they brewed an IPA and everyone is going to put a different dry hop in it.
It's been a lot of fun. We also brew 5 gallon batches on our own and take to meetings to taste, but this doing it in 45 gallon batches has been fun. Make beer, grille some brats, chicken and pork, and stand around the brew pot drinking beer all day.
