The korchma, translated in this project as tavern, was a genre of drinking establishment - one native to the Baltic provinces and the provinces formed from the lands of the Polish-Lithuanian Commonwealth. Coffee and tea were rarities in a korchma, as was the sale of food: local custom was to bring your own snacks. A korchma doubled as an inn, with two small rooms for travelers and a saray, or courtyard, for keeping animals and stowing goods. Read the entry in the Brokgaus-Efron Encyclopedia.
The atlas locates taverns in only nine provinces: Lifliand (1), Kurliand (10), Vilen (1), Grodnen (4), Minsk (2), Volynia (5), Podol'ia (1), Kiev (3), and Chernigov (1).
