Blavod
Blavod (blah-VOD) is an 80-proof black vodka distilled in the United Kingdom by Blavod Wines and Spirits plc. It is marketed on the liquor's unique black color that derives from Black Catechu, i.e. extracts from the heartwood of Burmese catechu acacia trees. Such additives do not interfere with the characteristics of the vodka, imparting no additional flavor or odour. Catechu also does not stain or leave a trace of other flavours.
