Fee Brothers Rhubarb Cocktail Bitters, 5 fl oz (150 ml) — Concentrated Vegan Bar Bitters for Cocktails

Built from flavor profiles available in 1800s America, Fee Brothers crafted this rhubarb bitters to bring a bright, tannic-fruit backbone to classic and modern mixed drinks. The 150 ml bottle stores a potent liquid concentrate—vegan and gluten-free—that bartenders and home enthusiasts use sparingly to balance sweetness, lift citrus, and introduce a subtle bitter edge. Its compact size and long shelf life make it a pantry-friendly bar staple for those who experiment with cocktails or refine traditional recipes.

How does Fee Brothers Rhubarb Bitters change the taste of a cocktail?

Rhubarb bitters add tart, slightly astringent notes and aromatic complexity without adding substantial volume. A few dashes can cut through sweet or syrupy elements, emphasize fruit and spirit characteristics, and contribute a layered finish.

• Adds tart, fruity bitterness that balances sugar.
• Enhances fruit-forward spirits like gin, bourbon, and rum.
• Delivers aromatic top notes that elevate scent and palate perception.
• Use 1–3 dashes per drink for most recipes; adjust to taste.

Which cocktails benefit most from rhubarb bitters?

Rhubarb bitters pair well with both spirit-forward classics and contemporary mixed drinks. They’re especially effective in cocktails that already include citrus, stone fruit, or barrel-aged spirits, where the bitters sharpen flavors and add a refined finish.

• Old Fashioned — adds fruit-driven tartness to brown spirits.
• Whiskey Sour — cuts through sweet components and rounds the profile.
• Gin & tonic or gin cocktails — complements botanical notes.
• Fruit-forward cocktails and shrubs — increases complexity and balance.

How should I store and use this 5 fl oz bottle to get the longest life?

Keep the bottle capped and stored in a cool, dark place away from direct heat or sunlight to preserve aroma and flavor. Because bitters are highly concentrated, only a few drops or dashes are needed per drink, which makes a 150 ml bottle last a long time even with regular use.

• Store upright in a cool, dark pantry or bar cabinet.
• Use an eyedropper or dasher top to measure 1–3 dashes (≈0.3 mL per dash).
• Refrigeration is optional; long shelf life due to concentrated formulation.
• Label indicates vegan and gluten-free formulation for dietary needs.
