Castle Brands has unveiled a special edition Knappogue Castle Whiskey, the company's founding brand.

Knappogue Castle 15 Year Old Irish Single Malt Whiskey was created using one cask each of single malt distilled in 1990, 1991 and 1992, the company said today (30 September).

The packaging will be different from Knappogue's traditional vintages, it added 

"Years ago, our blender identified these three casks as extra special and we did not include them in their respective vintage bottlings," said Roseann Sessa, vice president marketing and public relations for Castle Brands.

"The higher proof and lack of chill filtering lets the whiskey retain all of its natural flavour. Knappogue Castle 15 is a connoisseur's whiskey."

Knappogue Castle 15 Year Old will be available this season at select retailers, with a recommended retail price of US$100.
