Midleton Very Rare Dair Ghaelach Knockrath Forest is made from single pot still whiskeys aged for 15–28 years in ex-Bourbon barrels, and finished for 2 years in Irish oak. This unique expression is the third release in the first modern-day series of whiskeys matured in native Irish oak.

The Irish oak accentuates pot still spices on the nose, which also has hints of vanilla and roasted coffee, layered over fresh fruit evolving from orchard fruits to tropical notes. Pot still spices remain at the fore on the palate, accompanied by sweet notes, such as chocolate and honeycomb, coming from the Irish oak. The finish is long, with fading fruit and spices.
