Fever Tree is a UK-based producer of premium mixer drinks and tonics designed for use in cocktails and mixed drinks. The company specializes in crafting tonic waters, sodas, and other non-alcoholic beverages that function as essential components in spirit-based drinks rather than standalone products. Their range reflects a focus on providing high-quality ingredients for bartenders and home cocktail enthusiasts.

The tonics and mixers from Fever Tree are made with a emphasis on natural ingredients and distinct flavor profiles that complement rather than overpower the spirits they accompany. Their products include traditional tonic water alongside flavored variants such as elderflower and Mediterranean varieties, as well as soda water for those seeking a neutral mixer. Each variant is formulated to work with different spirit categories and cocktail styles, offering bartenders options beyond standard mixers.

The current range available includes Mediterranean Tonic, Elderflower Tonic, and Soda Water, each available in multi-packs of 20cl bottles. These mixers serve as functional components in a well-stocked bar, whether for professional use or home cocktail preparation.
