Short-Notice Kölsch

Brewed 5/10/11
Christy said "We're having a party for Memorial Day. We need beer." This is what I came up with on short notice.

Regardless, this batch came out OK. It's a little sweeter than I would prefer, and that crisp, lager-like finish is lacking. There is a hint of sulfur or mineral essence that I was told is a yeast byproduct. I was also told that this flavor dissipates over time, and that has yet to happen. Some of the problems might be due to the fact that this was never allowed to settle in a secondary fermenter - it went straight from primary to keg after nearly 3 weeks.

It's not my favorite, but it's certainly not my worst. I'll let it sit on tap for a while and see how well it ages.
