Last winter I went to a MABCAB (Milwaukee Area Brewers & Chicago Area Brewers) get together in Shorewood, WI. The guy who hosted it served a really good Kolsch. I've been wanting to brew one all year. Having not brewed any sort of lager or hybrid in awhile, the time finally arrived. I used his recipe, scaled up to 6 gallons so excuse the odd grain amounts, except that he used the same IBUs worth of Perle hops rather than Hallertauer. I've seen many recipes with Hallertauer though, and it's what I had on hand. (I need to start brewing some hoppier beers to get last year's hops used up!)
brewed on: 12/2/11
IBUs: 46.6 IBUs
mash temp: 149F
6 gallon batch
90 minute boil
75% efficiency assumed
5.38 lbs red Kolsch malt
4 lbs Pilsner malt
0.67 lbs Wheat malt
18.5 gm Hallertauer @ 3.9% - first wort (90 minutes)
39.5 gm Hallertauer @ 3.9% - 60 minutes
WY Kolsch strain - 2 liter starter
I overboiled by a bit and had to boil/top up with some water. Not a big deal. Back to 6 gallons. I'm hoping it didn't get too dark though.
primary: ~58F- raised to 62. Back down to 58-59.
