The Brugal Distillery was founded in 1888, by Andrés Brugal Montaner. Although the Edrington Group now controls the company, George Arzeno Brugal, is the current chairman, and most of the current board members are direct descendants of the original company founder. My understanding based upon discussions with the local Brugal Brand Ambassador for Brugal is that when the Edrington Group gained control of the rum company, they instituted a new wood policy which governs how all of the Brugal spirits are aged. This practice brings the cask selection process into line with the wood policy the company uses for its Scotch whiskies.
Although Brugal still makes their rum in a traditional manner (from molasses) and ages it on site in Puerto Plata, the Brugal 1888 (Ron Gran Reserva Familiar) now undergoes a special double maturation process. The rum is first aged in medium toasted, ex-Bourbon White American Oak Casks for 6 to 8 years. This is followed by a second maturation in first-fill Spanish Oloroso Sherry Casks.

El Pasador de oro XO is a new rum brand brought into Western Canada by Charton Hobbs. The rum is produced by Les Bienheureux S.A.S. (in Paris France) and (according to the information sheets given to me) is a blend ‘grand XO’ Guatemala rums aged from 6 to 15 years in oak barrels at selected Guatemalan distilleries. The rum undergoes a final aging process in France where the spirit is rested in used cognac barrels in the cellars of Les Bienheureux.
