Black to the Bones 4 Elements is inspired by the nature and it's 4 elements earth, water, air and fire. We created this thick and complex imperial oak aged milk stout together with 4 other Bulgarian companies that produce high-quality products and represent each of the nature's elements. EARTH (black wax): collab with Dabov Specialty Coffee. We added a blend of Brazilian and Kenyan 100% Arabica coffee and aged the beer with oak that was soaked in J Wray Jamaican dark rum.
