Catalunya is home to one of the oldest forms of wine making, a tradition for aged dry wines that pre-dates modern viticulture. Known throughout Roussillon as Rancio Sec (or alternately Vi Ranci), these are dry, unfortified wines that are often kept in the sun in glass demijohns, then transferred to partially filled old oak barrels for no less than 5 years. It is this oxidation process, further evolving over decades in soleras, that gives rise to the bouquet of unique tastes (fresh walnut, curry spices, cocoa, light bitterness) that characterizes Rancio Sec. Made in very small quantities, typically for the winemaker’s family and guests, its historic if endangered status is recognized by Slow Food France.
