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.)
