Kvass has been enjoyed in Russia and across parts of Eastern Europe for centuries, by every social group from Tsars to peasants.
Even today, in the summer you will see people lining up to purchase a glass of this tangy beverage from the street vendor’s barrel.
Kvass is a drink made from stale, dark, sourdough rye bread. It’s brown and bubbly, with a beer-like taste, but its alcohol content is so low (less than 1 percent that it’s considered non-alcoholic (although if left to ferment for long enough, the alcohol content will increase). It might be flavored with herbs, strawberries, raisins, currants, lemons, cherries, apples or mint. Hailed as one of the most thirst-quenching drinks available, Kvass is also considered to offer health benefits too, acting as both an isotonic and probiotic.
Kvass was often made at home; commercial production of it only began in the late 19th century. But, such is the product’s short shelf life (just a few days) it was frequently sold on the street, directly out of bright yellow mobile, barrel-shaped tanks. Customers would queue up to buy it by the glass, or in larger volumes, decanting it from the tank into the vessels they had brought from home.
Contribution to Retail History
In the Soviet economy, the sale of goods was a centralized process. Items and produce were brought to central depots for distribution through specific points of sale. In direct contrast, the Kvass barrel, alongside the beer barrel, was a way of distributing a high demand, perishable product quickly and efficiently, on every street corner, creating a myriad of ‘pop up’ retail distribution points. An important example of street vending in the Soviet Union, the Kvass barrel paved the way for other goods to be sold in this way, with numerous mobile food and drink vending points throughout streets of Russian cities, e.g. chains like Kroshka-Kartoshka or Steff.
