Mors (Russian: морс) is a non-carbonated Russian fruit drink[1][2][3] prepared from berries, mainly from lingonberry and cranberry (although sometimes blueberries, strawberries, raspberries or sea-buckthorn). It is made by boiling berries with sugar or just mixing pure juice with sweetened water[1]. Some modern commercial brands use fermented and clarified juices blending with sugar syrup and drinking water.
