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.
