The Glenlivet 15 Year Old French Oak Reserve is matured for most of its life in traditional oak casks; then, a portion is aged in new, specially coopered French Limousin oak casks. The final marriage of the whiskies from the Limousin and traditional oak barrels produces a unique, smooth spiciness that complements The Glenlivet"s mellow fruity flavors. Scotch whisky is not traditionally aged in Limousin oak, making this distinctive maturation an innovative process that reflects the pioneering history of The Glenlivet itself. The perfect dram for a sweet tooth, The Glenlivet 15 Year Old is best enjoyed after dinner.
