Coffee Cocktails and Coffee Tonics

Coffee tonic — espresso poured over tonic water and ice — became the barista's favorite summer drink in 2025, offering a bitter-sweet-effervescent combination unlike any other beverage. Specialty cafes in Scandinavia pioneered the format, and brands like Fever-Tree released coffee-specific tonic waters. The citrus and quinine notes of tonic water complement light-roast Ethiopian coffees particularly well.
