Boza's alcohol content is so low (about 1%) that it slipped past Ottoman-era drinking restrictions for centuries.
Boza is a thick, low-alcohol drink made by fermenting boiled millet, wheat, or bulgur with sugar and water until it turns tangy and faintly fizzy. Street vendors ladle it from tall jars into glasses and top it with a dusting of cinnamon, often alongside roasted chickpeas on the side. In colder months it's sold from carts and small kiosks across Bulgarian towns as a filling, cold-weather pick-me-up.
