Boza — Traditional Fermented Grain Drink

Boza is a thick, sweet-tart fermented grain drink associated with winter evenings. In Türkiye it is traditionally topped with cinnamon and roasted chickpeas (leblebi), and served cool—not boiling hot. Millet and bulgur versions both exist.

Home-style bulgur version

Ingredients

2½ cups bulgur; ½ cup rice; 8 cups water for cooking

½ teaspoon instant yeast; 1 tablespoon sugar; 1 cup lukewarm water

1–1½ cups additional sugar; up to 6 cups water to thin

Ground cinnamon and roasted chickpeas to serve

Method

1. Rinse the grains and cook in the 8 cups water until very soft. Press through a fine sieve; discard coarse solids.

2. Cool the strained base. Mix yeast, the tablespoon of sugar, and lukewarm water, then whisk into the base.

3. Cover and ferment in a cool place, stirring occasionally, for up to 24 hours; warm conditions shorten this substantially.

4. Stir in sugar and water gradually to a thick, pourable consistency. Chill, then serve with cinnamon and leblebi. Refrigerate and consume within a few days.

Important preparation note

This recipe has not been kitchen-tested by Taste of Türkiye. Fermentation depends on temperature, sanitation, and starter activity; elapsed time alone does not validate safety. Do not use smell or taste as proof of safety. Discard any batch with visible mold. Boza can contain alcohol from fermentation; it should not be described as guaranteed alcohol-free. Bulgur contains wheat/gluten. Commercially prepared boza is an alternative if you are not experienced with fermentation.
