Russian cuisine results in a beverage with very low alcohol content. Commercial kvass is often around 0.5% alcohol. The fermented liquid, referred to as "zator," is diluted with water and mixed with yeast, sugar, and aromatic additives. This final mixture is allowed to brew for several days. Flavor additives may include fruit and berry juices (cherry, raspberry, lemon, etc.), as well as ginger and mint. Sbiten, another non-alcoholic drink, is made of honey, water, fruit juices, and spices.

Kelluke ("Little bell", originally named after a Campanula) is a clear and lemon-flavoured non-alcoholic soft drink produced since 1965 by A. Le Coq (formerly and colloquially known as Tartu Õlletehas (Tartu Brewery)) in Estonia. After a temporary name change since 2001, Kelluke made its comeback in 2006. Since 2010 Kelluke has been produced without preservatives. It has been compared to Sprite, but the original makers of the drink were not familiar with Sprite before the recipe for Kelluke was finished. A. Le Coq A. Le Coq ()
