The Blavod vodka its unique black colour derives from

Blavod (blah-VOD) is a black British vodka. The brand was first launched in 1998 and is marketed on its unique black colour that derives from Catechu, an extract from the heartwood of Burmese catechu acacia trees. Catechu does not interfere with the characteristics of the vodka, imparting no additional flavour or odour and leaving no stains.
