Yes. We use roasted hazelnut as a botanical in Campfire London Dry Gin, Campfire Cask Aged Gin and Campfire Navy Strength Gin. The hazelnut is distilled and therefore the nut allergens remain bound in protein molecules left in the gin still at the end of the distillation process. Many other well-known gin brands include nut in their botanical line-up such as Bombay Sapphire who use ground almond. Campfire Old Tom Gin, Ultrasonic Gin, Domestique Gin and PUD PUD Christmas Gins do not include nut in the botanical line up.
