Bittermens Boston Bittahs (14.8cl, 44%)

Bittermens Boston Bittahs is a cocktail bitters built around citrus and chamomile, bottled at 44% vol in a 5oz dropper-style bottle. A few dashes add brightness, a floral edge and a lightly bitter lift to mixed drinks, from Martinis and Daiquiris to spritzes and highballs. It is a concentrated ingredient, to be used sparingly in a cocktail rather than taken on its own. The nose is bright citrus peel and chamomile with a gentle herbal bitterness. The palate is citrus-led and aromatic, with bitter orange, lemon peel and floral tea notes, and the finish is crisp and lightly bitter.
