Pimm’s No. 1 is a British gin-based liqueur with bitter herbs and citrus. It pours a rich amber hue as a result of infusing gin with herbal botanicals, caramelized orange, and delicate spices. Pimms No.1 dates back to the first half of the 19th century when it was concocted as a gin-based digestive by a farmer’s son who ran an oyster bar in London. This light and fruity liqueur is best served with fruit and mixers like ginger ale, sparkling lemonade, or Sprite.
