Traditional Lublin-region kvass: a homemade fizzy drink with under 0.5% alcohol

Kwas chlebowy (bread kvass) is a traditional fizzy drink from the Lublin region of Poland, historically consumed more often than water. It contains less than 0.5% alcohol, is refreshing and supports gut health. A family recipe passed down through generations allows it to be made at home as an alternative to shop-bought fizzy drinks.
