Finished in XO Calvados casks from the grazed orchards of Normandy in France which have formerly stowed apple brandy for over 6 years.

Glendalough's Double Barrel Irish Whiskey begins its maturation process in flame charred ex Bourbon American oak. It is finished in Oloroso casks from Montilla , a small town found in the rolling hills of the Spanish countryside. Glendalough choose the bodega, the liquid, the casks and the cooper in this region of Spain to deliver a terroir driven sense of this land , encapsulated in the liquid when we put our whiskey in these slow toasted casks for aging. These specially selected casks combined with expert liquid finishing, deliver a rich and complex flavour to our Double Barrel Irish Whiskey.
