Sbiten

Sbiten is a traditional hot winter beverage in Eastern Slavic cuisine, including Belarusian, Russian, and Ukrainian cuisines. Sbiten was a popular drink in Russian cuisine before the appearance of tea in Russia. It has a dark purple appearance and, depending on the recipe, can be very spicy and/or very sweet. It used to have the reputation of a Russian Glühwein, although it normally contains no alcohol. Modern sbiten can also be served cold during the summer or added to tea or coffee.
