Atlantico Reserva is their aged rum given a 3-part aging first for 3 years in American white oak, then blended and aged for an additional 2 years. Following is the solera aging of up to 15 years (solera being the tradition of retaining a portion of the oldest barrel to blend with the next oldest–we often think of the last portion of your gas blending with the new gas when you refuel your car… you can imagine there’s a tiny part of the very oldest gasoline from your first tank in there somewhere).
