Notes

Taste profile is a creamy mouthfeel with dark chocolate/mild coffee finish.

Toast flaked oats for 15 minutes @ 350, stir, repeat in 2 minute increments until golden brown
Toast cacao nibs at 300 for 12-15 minutes until they smell like brownies
Created a tincture with cacao nibs in muslin bag using vodka and soaking for several weeks.
Add the bag of nibs to the last 5 minutes of the boil and leave in while cooling wort.
Add tincture liquid post fermentation around day 7.

Clarity ferm used to reduce gluten.
