Notes

Recipe tailored to the black barley and chocolate malts I had on hand. Single origin for each would be fine

5 of 5

10/14/19 version: Tan lingering head. Aroma is bitter-sweet chocolate fading to dark dried fruit. Flavor is chocolaty with brief maltiness fading to roast and drying balance. Bittersweet chocolate lingering finish. Full creamy body.
