Spanish For Anise.
Ojen is an aguardiente from the eponymous village in the province of Malaga, Spain. Aguardiente is a portmanteau of the Spanish words for water (agua) and burning (ardiente), and is the generic reference for an alcoholic drink between 29 and 60 percent alcohol. Aguardiente de Ojen is flavored with anise and thus, like absinthe, creates a louche when mixed with water. When the two combine, the anise oils emulsify and disperse evenly throughout the water, creating the milky-looking liquid pictured above.
