Fee Brothers Black Walnut Bitters 5OZ is a glycerin-based cocktail bitters delivering concentrated black walnut flavor at 6.4% ABV in a 5-ounce dasher bottle. Scored 93 points by tastings.com in 2013, this expression stands as one of the few commercially available black walnut bitters on the American market — a genuinely distinctive modifier in a category crowded with aromatic and citrus options. Quick Facts: ABV: 6.4% | Origin: Rochester, New York, USA | Style: Black Walnut Bitters | Producer: Fee Brothers Production & Heritage Fee Brothers has been producing bitters and drink mixers in Rochester, New York since 1864, when four German immigrant brothers established the company. Unlike most bitters producers that build their formulas on a high-proof spirits base, Fee Brothers uses vegetable glycerin as its foundation — a technique the company adopted during Prohibition and has maintained ever since. The Black Walnut expression is flavored with natural black walnut flavoring along with a blend of other natural and artificial extracts, resulting in a viscous, intensely nutty modifier that behaves differently from spirit-based alternatives, contributing body and sweetness alongside bitterness. Tasting Notes Aroma: Toasted walnut leads immediately, followed by bark-like cola and subtle warm spice. Deeper earthy undertones emerge with time, hinting at cocoa and roasted nuts. Taste: Bold black walnut flavor arrives on the palate first, with a sweet undercurrent of molasses and caramel building through the mid-palate. Notes of hazelnut and unsweetened chocolate develop as the bitterness gently asserts itself, balanced by the glycerin base's natural sweetness and smooth mouthfeel. Finish: A lingering nutty bitterness anchors the finish, accompanied by a root-beer-like herbal quality and a faint touch of residual sweetness. The overall impression is warm, rounded, and moderately long. How to Drink Black Walnut Bitters Two to three dashes is the standard measure for most cocktail applications; this is a modifier, not a sipping product. The rich walnut and molasses character makes it a natural fit for dark-spirit cocktails. Old Fashioned: Replacing or blending with standard aromatic bitters adds a roasted, nutty depth that pairs exceptionally well with bourbon or rye. Manhattan: A dash or two introduces an earthy complexity that complements sweet vermouth and aged whiskey without overpowering the drink. Espresso Martini: The cocoa and walnut notes mirror and amplify coffee's roasted character, adding a layer of bitterness beyond what the espresso alone provides.
