American 2-row
American 2-row
Yields a slightly higher extract than Six Rox brewers Malt. Tends to give a smoother, less grainy flavored beer. Some brewers claim they can detect a significant difference in flavor. Lower protein and will yield a lower color than Six-Row Brewers Malt

Fermentis K-97 Safale K-97
Fermentis K-97 Safale K-97
A German ale yeast selected for its ability to form a large firm head when fermenting. This top cropping ale yeast is suitable for top fermented beers with low esters levels and can be used for Belgian type wheat beers. Sedimentation: low. Final gravity: low. 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. 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. 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.
Notes
Infusion Mash - single step, 149 F for 60 minutes, strike with 12.5 qts at 160 F. Mash out at 168 for 10 minutes; strike with 8 qts at 200 F. 10 gal SS HLT, 5 gal gott MT, 12 gal BK. Amb. temp = 85 F. Denver (Foothills) water - soft, diluted with 20% distilled H20. Hydrate K-97 yeast 30 minutes prior to pitching. Ferm temp 68 F. Mash Efficiency was lower (60%) than expected (70%). 1 lb corn syrup was added to compensate

Brew Log

7/28: First use of new all grain gravity system (10 gal SS HLT, 5 gal Gott MT, and 12 gal SS BK). Mash pH was 5.2-5.4 using Denver (~soft water). Mash Efficiency was poor (60%): probably due to poor sparging process. Added corn syrup (1 lb 2 cups H20 mini boil) after main boil was completed (will make sure I have some DME on hand in the future). Measured OG of 1.037 should be ~1.043 (calculated). Good cold break using coiled wort chiller: 80 F is < 30 minutes. Ambient temp of 85 F. Yeast hydrated for 30 minutes and pitched at 80 F. I set up an evaporative system (t-shirt covered carboy sitting in a pan of H20 with fan blowing on it). Currently in 6.5 gal primary with an initial temperature of 68 F. 7/29: Fermentation is going strong. Carboy temp is 65 F. Slight whiff of sulfer from the K-97. Nice krausen. 7/31: Still chuggging along. Temp is 64 F. 8/4: Krausen has started to drop out. Transferred to 5 gal secondary. Temp. is 64 F. 8/21: Bottle with 3/4 cup corn sugar.
Much improved from my last attempt

Slight hop aroma, very smooth. Very clear. Hit the color. Nice balance.
