Glendalough Distillery is part of a revival of this Irish heritage. Their philosophy is "to make innovative spirits while staying true to the tradition and heritage of our ancestors." Glendalough started out making poitín ― the traditional Irish distillate made in small pot stills. From there they seamlessly transitioned to whiskey production, and most recently, seasonal, wild botanical gins. All of their production is handmade.

The Glendalough 17 Year Old Single Malt was aged in first-fill bourbon casks for 15 years, gaining a layer of citrus notes atop the sweet honey and vanilla. It was then transferred into rare mizunara oak barrels from a Japanese island some 6,000 miles away. These impart the liquid within with a luxuriously creamy mouthfeel and immense complexity. Only 6,000 bottles of this luxurious expression were produced.
