Low efficiency due to use of the no-sparge method. Actual OG: 1.073, FG: 1.011 .4 grams of gypsum per gallon in the mash = 4.4 grams of CaSO4 (Gypsum) .4 grams of calcium chloride per gallon in the mash = 4.4 grams of CaCl This will yield approximately between 75-100ppm Ca in the mash whirlfloc at 15 minutes yeast nutrient at 10 minutes Stir plate starter calculated using Jamil's mrmalty.com pitching rate calculator . Make 2 starters, split between 2 5 gallon carboys. For each starter: # of yeast cells needed (in billions): 386 # of yeast vials needed: 2 # of liters of starter required: 1.40 (1400 mL) amount of DME necessary: 140 grams / 5 ounces. DME: Use a 10 to 1 ratio. Add 1 gram of DME for every 10 ml of final volume. (If you're making a 2 liter of starter add 200 grams of DME to the flask, then fill the flask with water until you have 2 liters total.) 2 5 gallon carboys used for fermentation yeast strain split between wyeast 1056 and white labs 001 2 dry hops, 1 7 days into fermentation, 1 14 days into fermentation. for each dry hop: .60 oz. centennial/simcoe 1.25 oz columbus |
