Copper Alley is the second expression from the distillery and joins Oak Devil in the premium Irish whiskey range.

The limited release is double barrelled, with 10 years in Bourbon casks and finished in 30 year old Oloroso Sherry casks for six months. Bottled at 46%, the non chill-filtered variant is on global release from this month for €50.

Darryl McNally, master distiller, said: “My inspiration for Copper Alley was going back to the original methods of Irish whiskey making. Having rested for 10 years in Bourbon casks, I felt it just needed something extra to really bring it to life. Working with our cask partners, I came across some 30 year old Sherry casks of exceptional quality which I knew would give the whiskey an edge. This is a one off – there are only 31 casks, so this is a whiskey which will be little repeated.”

Quintessential Brands global marketing manager Sinead O'Frighil, added: “Irish Whiskey has experienced phenomenal growth over the past number of years and this is a trend which is set to continue. We see great opportunity at the top end of the market, which is growing strongly. Premium Irish whiskey is growing at 25% year on year and we are seeing great consumer interest in new and distinctive brands”.
