I'm doing 6 cases of beer for an event (it's as much about the labels as the beer so I can't do kegs).
So, I need some bottles. Plus, now that I've been home brewing a lot for the past couple years, I just don't buy much beer anymore.
Also, since this is for an event, I don't want to risk a dirty bottle.
I have some pop tops that I'll reserve for the few competitions I go in cause I don't want to risk screw offs for that.
