Koln Blow
Kölsch • All Grain • 22 gal
Per usual, we like to attempt beer styles with the grains and yeast we have on hand. A better choice for yeast (giving better attenuation) would be Wyeast 1007 German Ale, or of course Wyeast 2565 Kolsch. Still, we're going to relax, have a homebrew, and use the Wyeast 2112 California Common of which we have a goodly slurry.

Irish Moss - Irish Moss (omitted from calculations)
Irish Moss
A dried red-brown marine algae. Fining agent to remove large proteins. Negatively charged polymer attracts positively charged protein-tannin complexes (extracted from grain husks and hops) during the boil. This action is aided by the clumping of proteins in the boiling process. Irish moss settles to the bottom of the brew kettle with spent hops and hot break material at the end of the boil.

Fermentis US-05 Safale US-05
Fermentis US-05 Safale US-05
The most famous ale yeast strain found across America, now available as a ready-to-pitch dry yeast. Produces well balanced beers with low diacetyl and a very clean, crisp end palate. Sedimentation: low to medium. Final gravity: medium. Pitching instructions: Re-hydrate the dry yeast into yeast cream in a stirred vessel prior to pitching. Sprinkle the dry yeast in 10 times its own weight of sterile water or wort at 27C± 3C(80F ±6F). Once the expected weight of dry yeast is reconstituted into cream by this method (this takes about 15 to 30 minutes), maintain a gentle stirring for another 30 minutes. Then pitch the resultant cream into the fermentation vessel. Alternatively, pitch dry yeast directly in the fermentation vessel providing the temperature of the wort is above 20C(68F). Progressively sprinkle the dry yeast into the wort ensuring the yeast covers all the surface of wort available in order to avoid clumps. Leave for 30 minutes and then mix the wort e.g. using aeration.
