Brewing Kölsch

So my first attempt at Kölsch came out really delicious, but I over-hopped it a little for the style, leaving me with something more reminiscent of a German Pilsner than a true Kölsch. So the second time around (with the 5th generation of the same packet of yeast), I decided to hop it a bit less aggressively and give myself something more properly Kölsch-like. I did 10 gallons, and then kegged half of it unfiltered for an SF beerweek event, and the other half has received a longer lagering time in my freezer and will be the first beer put through my new (and not yet arrived) beer filtering system (thanks to my girlfriend's mom and stepdad for the gift certificate that led to the purchase).

Anyway, here is the recipe and I will post a picture of a glass of the Kölsch when it is all nice and filtered.
