I needed to take a keg to work in a hurry but didn't have a full one of anything I was prepared to see kicked, so I blended what was left of some other kegs I had lying around: Belgian pale ale, Scottish 70, Oktoberfest, and Schwarzbier, then adjusted it to taste with Biere de Garde, Belgian Blonde Ale, and some Imperial Stout to make artisan-style Belgian brown ale loosely in the Verboden Vrucht vein. I put a little sign on it that just said it was "malty, fruity, spicy, somewhat strong" and said it was a Belgian brown ale.
I also brought two cases of some pretty good craft beer (Sierra Nevada Tumbler and Torpedo, Great Lakes Oktoberfest and Nosferatu, Troegs Sunshine Pils and Hopback Amber). There were maybe three bottles consumed, while the keg was nearly gone.
In case you think the people didn't know anything about beer, there was about a case of mixed bottles of various Sam Adams stuff, Bud Light, and Mike's Hard Lemonade left over from some other function. Not a bottle of that was touched.
I wasn't shooting for any particular target; I just wanted to make something that tasted good. So I blended to taste. Everyone was happy, and now I have four additional free kegs heading into brewing season.
