Each bottle is built from real ingredients and bartender know-how, so all you have to do is add your favorite aged spirit. One quick, easy pour and you are set. Anytime. Anywhere. And every single time.

Maple Bacon Proof Syrup

Smoky, savory, and just sweet enough. Maple Bacon brings rich maple notes with a subtle cured bacon finish that plays beautifully with bourbon and rye. It is bold without being gimmicky and turns a classic Old Fashioned into something guests talk about long after the glass is empty.

⸻

Orange Proof Syrup

Bright and citrus forward, this one hits the sweet spot between fresh orange peel and balanced sweetness. It delivers that essential citrus backbone every Old Fashioned needs without muddling or fuss. Clean, classic, and endlessly versatile.

⸻

Pecan Proof Syrup

Warm, nutty, and smooth, Pecan Proof Syrup adds depth and a Southern twist to your pour. Think toasted pecans with a gentle sweetness that pairs especially well with bourbon and aged rum. Comforting, rich, and incredibly drinkable.

⸻

Black Walnut Proof Syrup

Deep, earthy, and complex. Black Walnut is for those who like their Old Fashioned a little darker and more contemplative. The natural bitterness of walnut adds structure and richness, making this a favorite among serious whiskey drinkers.

⸻

Sazerac Proof Syrup

Inspired by the iconic New Orleans cocktail, this syrup brings bold spice, subtle sweetness, and classic aromatic depth. Perfect for building a Sazerac at home or adding a twist of Creole character to your Old Fashioned lineup.

⸻

Traditional Proof Syrup

This is the OG Proof Syrup. The very first flavor and still the top seller. Made from organic cane sugar, real citrus oils, and the best aromatic bitters in the world. This syrup is not a substitute for the real ingredients. It is the real ingredients. Perfectly balanced, bartender approved, and the foundation every home bar should be built on.

Whether you are hosting friends, pouring one after a long day, or building cocktails on the go, Proof Syrup makes a proper Old Fashioned effortless and consistent, every. single. time.
