The kvas vendor fills out a glass for each of us. I was over the moon for having finally tracked down one of these yellow trailers selling this traditional drink. My guide and driver were fascinated too, as they thought the concept had become extinct. Kvass is made by the natural fermentation of bread, such as wheat, rye, or barley, and sometimes flavoured using fruit, berries, raisins, or birch sap collected in the early spring. Modern homemade kvass most often uses black or regular rye bread, usually dried (called plural suhari), baked into croutons, or fried, with the addition of sugar or fruit (e.g. apples or raisins), and with a yeast culture and zakvaska (kvass fermentation starter). As its primary ingredient is rye, kvass is a good source of vitamin B-1 and B-6, magnesium, phosphorus, amino acids, and pantothenate. It is also rich in lactic acid and simple sugars, which contributes to its pleasant, thirst-quenching taste, provides ample calories to fuel physical activity, and may improve digestion, as with other lacto-fermented foods such as yogurt and sauerkraut. How I wish we could find it here in Dubai! Some probiotics would do our system good. (Baku, Azerbaijan, Sept. 2017)
