Notes

If not using GigaYeast or a straight pitchable yeast, create a starter and aim for 200+B yeast cells. (Standard Starter)

Mash the crushed grains in 1.5 gallons of water at 155F for 45 minutes. Strain the grains and sparge with 1.5 gallons of water at 170F. Mix in malt extract and lactose sugar.

Bring wort to a boil. Add hops and adjuncts as scheduled. Whirlpool, chill, and transfer to a clean, sanitized fermenter.

Mix in enough clean, sanitized water to make five gallons. Pitch yeast at 70F and ferment at 65-70F for ten days. Pitch to Secondary Fermenter and ferment for ten more days. Bottle or keg as normal, except mix in 1 tbsp of vanilla extract with the priming sugar.
