The term 'Tavern Supply' refers to the supplies needed to run a tavern, which is an establishment that serves alcoholic beverages. The two main supplies needed for a tavern are LIQUOR and ICE. LIQUOR is an alcoholic beverage made by distilling fermented grain, fruit, or vegetables, and it is typically sold in bottles or cans. ICE is a frozen form of water that is used to cool drinks. Both of these supplies are essential for running a successful tavern.
