Ron Abuelo XV 15 years Tawny Port Cask Finish is part of Abuelo's 2016 Collection Finish releases, which also includes an Oloroso Sherry Finish and a Napoleon Cognac Finish. There has long been a big jump in price (and quality?) From Abuelo's 12-year-old edition to their exclusive Centuria edition, and with Ron Abuelo XV's 15-year-old Tawny Port Cask Finish we were to get a rum that lies between these 2. The rum should be selected from among Abuelo's finest reserves, and after an initial storage in American oak barrels, the final storage has taken place in Tawny Port barrels.
