Once You Go Black is a dark Milk Stout from Brouwerij Klein Duimpje in Hillegom, brewed with lactose for a creamy texture. The beer balances bitter and sweet notes, enhanced by blackberries and caramel-forward malt. Per 15 hectolitres, 40 kilograms of blackberries are added, shaping the stout's character.

Lactose keeps this stout approachable without sacrificing dark, full-bodied flavour. Blackberries contribute fruity notes, while the malt bill brings caramel and subtle toastiness. A beer that holds sweet and bitter in equilibrium, ideal for those exploring darker stouts.
