Notes

This recipe uses British malts for the light crystal, brown malt, chocolate, and roasted barley. SRM will change significantly if American malts are used.

Target (approx.) IBU's (75) from North Coast web site.

At ten minutes remaining, add 1/2 cup yeast nutrient.

SafAle K-97 pitch rate is 50-80 g/hL. High OG; high end of pitch rate (80 g/hL). 25 gallons = 1.13 hL. 1.13 hL x 80 g/hL = 90 grams = approx. 9, 11 gram sachets.

Hydrate with 800 mL (10 mL per 1 gram of yeast) of PropaPitch starter. Let stand 10 minutes. Stir. Let stand additional 10 minutes.

Ferment at 65 degrees until 2/3 complete, then ramp 1 degree per day to 70.
