BrewBlog: Harcombe American Kolsch

Specifics

Style:

Category:	Light Hybrid Beer
Number:	06C

A clean, crisp, delicately balanced beer usually with very subtle fruit flavors and aromas. Subdued maltiness throughout leads to a pleasantly refreshing tang in the finish. To the untrained taster easily mistaken for a light lager, a somewhat subtle pilsner, or perhaps a blonde ale.

Commercial Examples: Available in Cologne only: PJ Früh, Hellers, Malzmühle, Paeffgen, Sion, Peters, Dom; import versions available in parts of North America: Reissdorf, Gaffel; Non-German versions: Eisenbahn Dourada, Goose Island Summertime, Alaska Summer Ale, Harpoon Summer Beer, New Holland Lucid, Saint Arnold Fancy Lawnmower, Capitol City Capitol Kölsch, Shiner Kölsch.

General Information

Method:	All Grain

Method:

All Grain

Malted Harcombe Farm (Corvalis, OR) barley as per Homebrewer's Garden. No aerator, so I just did multiple soaks.

Aiming for Kolsch style.

Missed:

IBU about 10 units too high, also not German noble hops.

OG too low @ 1.039. Style lower limit is 1.044.

Otherwise, color and attenuation are on the mark.

Procedure

2 lbs of Harcombe pale malt was crushed in a coffee grinder. I know, I know... not a good idea. Learned the hard way here. Dough-in at 130F (1 gallon water), cooled to around 125. Steeped for 20 minutes at 125F. Raised temp to 144F by boiling water addition (probably 2 qts). Held temp for 20 minutes. Raised to 154F, held for 30 minutes. Mash-out at 170F for 10 minutes. (n.b. 1 gallon volume was REALLY hard to maintain temperature.) Boil for 60 minutes. 1 gallon was nice for getting a nice hard boil. Finings (1/4 tsp) and nutrient (1/4 tsp) added at 15 min out. Chilled outside (ambient 5F) to 65F. Pitched onto BRY-97 starter.

Special Procedures

BRY-97 starter made from single colony isolate from Batch #2. Grown in 1 qt of SG 1.038 (DME + 1/4 tsp yeast nutrient) for four days with occasional vigorous agitation. Seemed to be pretty happy.
