Notes:
Recipe was for 5g @ 70% efficiency for a much higher ABV. When scaled water for 5.5 @ Fermenter & 60% efficiency, hit the target (low 6%) ABV for base beer. However, the Donuts added quite a bit of Gravity.
Hops: Reduced hops by 20% to adjust for the affects of not aging.
Coffee: Changed the coffee addition to a secondary process of whole bean.
Donuts: Added Donuts to the recipe. Target 0.5# in Mash & 0.5# in Boil. Donuts will add more sugar and bump up ABV.
Vanilla: Added Vanilla to the recipe. On brew day, create Vanilla tincture (1 Vanilla Bean, cut & scrapped with husk cut up, in a jar with 2 tbsp of Vodka). Pour into secondary.
Ferment for 2 weeks.
2 days later, Cool to sub-40 (or as close as you can get). Pour in Vanilla tincture & add 5 oz of whole coffee beans (in a hop sack) to 5 gallons of beer for 1-3 days (to taste).
