Varela-Hermanos distills their rum from estate-grown sugar cane, which is aged in oak casks. Ron Abuelo Centuria rum is named in honor of the distillery''s 100th anniversary and is a blend of rums aged "up to" 30 years. It is a solera style rum, which typically means that a portion of the oldest barrel is maintained after bottling to marry with the next oldest (think of the gasoline in your car as a solera system where there are traces of the very first tank of gas still there in the present unless you ran the thing dry). It is a limited release of only 200 cases imported to the United States. In a sterling review from the 2011 Beverage Testing Institute, they called it "A fantastically flavorful and balanced sipping rum that will go great with cigars."
