I roast coffee. I am a complete and total 100% coffee geek. And when I tasted this at the Royal Coffee booth at the San Francisco Coffee Festival in 2024 — I almost fell over. This thing is a magic elixir.
The Blackberry Espresso & Tonic is bold, complex, and zero proof — Top Hat Cold Brew Coffee Concentrate and Top Hat East India Tonic joined by blackberry syrup for deep fruit depth. Rich, bitter, fruity, and endlessly sessionable. You have to try this. Build it with the can or make it on your soda maker.

The blackberry syrup does double duty — deep fruit, deep color, a violet bloom at the bottom of the glass. Cold brew adds roasted backbone without fighting the tonic. The quinine and the cold brew are natural partners. Royal Coffee figured that out first. We just made it easy to replicate at home.
