Special Procedures

Water adjustments to RO: 0.75 grams/gallon gypsum; 1.0 grams/gallon calcium chloride.

  • Mash additions: 5.5 grams calcium chloride, 3.5 grams gypsum. 
  • Sparge additions: 3 grams calcium chloride, 2 grams gypsum.

Add 0 minute aroma hops to whirlpool or hop stand for 15 minutes.

Add dry hops to primary 3 days into fermentation. Why? According to an analysis of dry hopping studies:

If you want to take advantage of biotransformation, which can lead to more of a rose/citrus/fruity aroma from the conversion of geraniol to citronellol, add dry hops early in the fermentation process while the yeast are still present and active.
