Bitters

Bitters are highly concentrated botanical extracts containing intensely bitter, aromatic, and herbal compounds, used in small quantities as cocktail flavoring agents. They typically contain alcohol as a carrier but are used in such small quantities (dashes) that their contribution to overall drink ABV is minimal, making them generally acceptable in zero-proof cocktail contexts.

Bitters originated as medicinal preparations — concentrated herbal tinctures prescribed for digestive complaints, fever, and various ailments. Angostura bitters (originally produced by Dr. Johann Siegert in Venezuela, 1824) was marketed as a stomach tonic before becoming the world's most popular cocktail bitters. Peychaud's bitters (New Orleans, 1830s) was similarly medicinal in origin. The transition from pharmacy to bar reflects the culinary value of bitter botanical complexity independent of medicinal effect.

Conventional bitters contain 35-50% ABV alcohol as a carrier and preservative for the botanical extracts. Because they are used in dash quantities (0.5-2ml per cocktail), their contribution to the final drink's ABV is minimal — a single dash of Angostura bitters adds approximately 0.003% ABV to a 300ml cocktail. Most zero-proof cocktail communities and 'mocktail' recipes therefore accept conventional bitters as compatible with zero-proof drinks, though purists may prefer alcohol-free bitters alternatives.

Alcohol-free bitters are now available commercially (Ethanol-free Angostura Bitters is not available, but brands including Fee Brothers Molasses Bitters and several craft producers offer low-alcohol or alcohol-free alternatives using glycerin as carrier). These allow zero-proof cocktails to include the bitterness and botanical complexity of bitters without any ethanol contribution.

A craft dimension: the artisan bitters market has expanded dramatically, with producers creating sophisticated, single-botanical bitters (lavender, cardamom, rhubarb, black walnut) and regional terroir-specific bitters that function as sophisticated flavor modifiers for zero-proof cocktails. Understanding bitters categories — aromatic (Angostura-style), citrus, mole, herbal — enables zero-proof mixologists to construct complex flavor architectures with just a few dashes.
