★★★★★ Manhattan

Absolutely Love It! Takes the work and measurements doubt out of the perfect Manhattan ♥️

- Carolyn B.

★★★★★ Ham on Rye

Ok, I did purchase the Proof Maple Bacon Syrup just to make this drink. And oh what a drink it is! Complex, smoky, with a hint of sweetness. A slight twist to the traditional Old Fashioned. Proof Syrups have transformed my home bartending game!

- Janet H.

★★★★★ Orange Old Fashioned

I love this syrup for my old fashioned! The sweetness of the syrup and the orange flavor pair well with my favorite higher proof bourbons and make for a very enjoyable drink.

- Patrick K.

★★★★★ Mojito

Mixed with white rum per instructions, added some mint and lime for appearances. Tasty, refreshing, and SO easy! Satisfied my mojito craving with like 10% of the usual effort. WIN!
