Sumac

Sumac (Rhus coriaria) is a Middle Eastern shrub whose dried berries produce a tart, tangy, fruity-acidic spice widely used in Lebanese, Turkish, and Persian cooking. In zero-proof beverages, sumac provides a distinctive sour-fruity acidity with notes of tamarind and lemon zest.

Sumac's tartness comes primarily from malic acid and tartaric acid, along with a complex polyphenol profile including anthocyanins, gallic acid, and hydrolyzable tannins. The flavor is distinctly different from citrus acidity — more berry-like, slightly astringent, with a red fruit undertone that integrates well with both sweet and savory flavor profiles. It has been used as a souring agent in Middle Eastern cooking since antiquity, predating citrus cultivation in those regions.

For zero-proof cocktail production, sumac offers an alternative acidulant that brings far more flavor complexity than lemon juice or citric acid solution. Sumac-steeped water or sumac syrup (ground sumac macerated with sugar syrup, then strained) can serve as the acidic component of a zero-proof sour or highball while adding color (a deep magenta-pink) and aromatic complexity simultaneously.

Sumac is also nutritionally interesting: its gallic acid and quercetin content are associated with antioxidant activity, and some research has explored potential glucose-lowering effects — relevant for the functional wellness positioning that many premium zero-proof beverages pursue. The anthocyanin content gives sumac-based drinks a distinctive color that consumers associate with health and plant-derived nutrition.

A culinary crossover: sumac's use is expanding rapidly in European fine dining, driven by chefs like Yotam Ottolenghi who have brought Middle Eastern ingredients to mainstream European culinary culture. This culinary exposure creates consumer familiarity with sumac that zero-proof beverage brands can build on, positioning sumac-forward drinks in a context of sophisticated food culture rather than exotic novelty.
