Seasn Dark Cocktail Bitters is the darker expression in a two-product range from Ben Branson, who previously founded Seedlip. Made in the UK, the 150ml bottle is designed to yield around 50 serves, positioning it as a concentrated cocktail ingredient for both alcohol-free and conventional drink builds. The Dark sits alongside the Seasn Light Cocktail Bitters in the range, and both are formulated without sugar or GMO ingredients.
