Riga Black Balsam

Riga Black Balsam is a traditional Latvian balsam often considered to be the national drink of Latvia. According to tradition, only the Head Liquor Master and two of his apprentices know the exact recipe. Nowadays, Riga Black Balsam is produced by JSC Latvijas Balzams and has received more than 100 awards at different international fairs throughout its history. More than 2 million bottles of Riga Black Balsam are produced each year and exported to 30 countries. There are several variations of the balsam with blackcurrants, cherries, and even brandy. The traditional recipe was created in 1752 by Abraham Kunze [ru], an apothecary living in Riga. In 1762, Kunze published an advertisement for the balsam in the December 23rd issue of the Rigische Anzeigen [de] newspaper, describing its purported healing properties and instructions for use and offering it in flasks, cruses and bottles of an unspecified volume sealed with wax with his initials (A.K.) pressed in them for a price of two state thalers for a shtof.
