Taste Notes

From the “Bible” pg 146 of Homebrew Beer by Greg Hughes Batch Vol: 6.50 gal Calcium: 81.1 ppm - Magnesium: 0.0 ppm Sodium: 7.9 ppm - Sulfate: 89.5 ppm Chloride: 89.9 ppm - Bicarbonate: 0.0 ppm Residual Alkalinity: -57.9 ppm Sulfite/Chloride Ratio: 1.0


1. ONLY mash malts/grains that require it. DO NOT mash malts that don’t require it. (Dark Crystal and Roast malts.) They screw with pH. Hold Dark Crystal and Roast malts to Mash Out (15 minutes)/Sparge (15 minutes). (30 min hot steep) 2. After deoxygenating with 2g/gal ea yeast and sugar, pretreat total brewhaus liquor to ~5.5 pH. I use 1/8 tsp 10% Phosphoric Acid in 9 gal Distilled Water. Add 1/2 tsp Brewtan B hydrated to 5 gal. strike liquor only prior to mash in. Sparge with 4 gal reserved brewhaus liquor. 3. Adjust Mash with 1 tsp CaCl, or 1 tsp Gypsum, or a combo of the two to equal 1 tsp total. Add direct to MLT on top of grain. (~50 ppm Ca in 5 gal mash volume). Use calcium sulfate in English styles, calcium chloride in German, Czech, and Belgian styles, and a mix of the two in American styles. Avoid sulfates when using noble hops. 4. Add any other salt additions to the boil targeting post boil volume concentration.
