Well, I'm breaking tradition here a bit in this thread and posting a very positive experience. We were invited to a neighborhood holiday party the week before Christmas, so, back in early November, I brewed up 5 gallons of my House Amber that I brew. It's a little hoppy, a little malty, but over all a pretty good beer to introduce someone into homebrew. The hose had been to my house a couple of times and it was his suggestion that I bring some homebrew.
So, I split the batch between my two 2.5 gallong kegs I have. The one I put on gas and got it carbed up for the party. Initially I was a little nervous bringing a whole 2.5 gallons to the party. It was a weeknight, family oriented, so I wasn't sure if that was going to be too much for this situation.
Turns out, my fears were unfounded. I was really kind of surprised. Everyone who came to the party was anxious to try it. Most responses were, "wow, this is homebrew, this is really good." Now, it could have easily been the convenience of the mini keg, with the tap just sticking out of it, but when another good friend from the neighborhood finally arrived about an hour after I did, he couldn't wait to try the homebrew. He got one glass, then it kicked.
Everyone kept coming up to me the rest of the night asking if I had another keg of that beer, it was really good. Now, don't get me wrong, I'm really not trying to brag about my beer. It's more that I'm just so used to the majority of people I meet being BMC drinkers, that usually you get the obligatory, "Um, yeah, it's OK, I like my light beer though." It was a really nice change of pace to see people enjoying a beer that wasn't your typical mass appeal party beer.
