5 Ways to Elevate Your Cocktails

Add flavor, complexity, and balance to your cocktails with Proof Bitters. Incredible in Old Fashioneds, tiki cocktails, manhattans, martinis, sours, and numerous other fine libations, Proof Bitters are the unique, premium bitters experience you’ve been looking for.

Peach Bitters

We steep real peaches with aromatic spices and earthy, bittersweet gentian root to create these balanced, warmly spiced bitters. The result is a fresh, subtle fruitiness that’s incredible with aged spirits and wine-based cocktails. We’re loving these bitters in Old Fashioneds, sours, and champagne cocktails.




Lemon Peel

Gentian Root



Coconut-Pineapple Bitters

We steep coconut and fresh pineapple with a unique blend of Asian and Caribbean spices to produce the distinctly tropical flavor of these bitters. They’re perfect for tropical, tiki, beach and summer cocktails, rum cocktails of all kinds, and a tall, refreshing bitters and soda.






Black Walnut Bitters

The key ingredient in these bitters? Time. We slow-roast black walnuts, then steep them with aromatics for six weeks to create nicely spiced bitters with a cocoa-like sweetness and the slight earthy fruitiness characteristic of black walnuts. These bitters are perfect for both aged and distilled spirits.



Black Walnuts


Pecan Bitters

To create these bitters, we start by slow-roasting Georgia pecans to draw out their natural sweetness. Over the next few weeks, they’re steeped in alcohol, stirred, and tasted and re-tasted to create perfect pecan bitters. Delicious in classic and tropical cocktails, our pecan bitters are a perfect fit with bourbon, rum, and other aged spirits.




Orange Bitters

These are no ordinary orange bitters. By combining organic orange peel with a proprietary mix of spices, we created flavors that are exotic and distinctive, yet homey, warm, and inviting. Enjoy in your cocktail of choice, or with club soda and an orange wedge over ice.
