Seattle distillery Copperworks Distilling Company has released an amaro cask-finished single malt American whiskey and gin.The single cask releases have been launched as part of a collaboration with Seattle's Letterpress Distilling, which used casks that previously held Copperworks spirits to age its amaro. These casks were then sent back to Copperworks for the team to use again. One cask was a 53-gallon American Oak barrel that was first used to mature Copperworks American Single Malt Whiskey, while the other was a 53-gallon American Oak barrel first used to finish Copperworks New Oak Cask Finished Gin. The whiskey rested in the amaro cask for more than seven months and the gin for nearly 10 months. “We were honoured to have the opportunity to taste Letterpress Amaro Amorino throughout its development,” said Jason Parker, Copperworks co-founder and president. “When we tasted the final version, we all agreed it would be perfect for ageing in two of our barrels: one barrel that aged Copperworks American Single Malt Whiskey and one barrel used to finish our New Oak Cask Finished Gin. “The barrels came back to us with amaro flavours in the wood and we filled the whiskey barrel with our American Single Malt Whiskey and the gin barrel with Copperworks Small Batch Gin. We’re thrilled with the resulting amaro cask-finished spirits.” Copperworks American Single Malt Whiskey, Release 17 (Amaro Cask Finished) is limited to 290 bottles (50% abv) at an RRP of US$76.49. Copperworks Amaro Cask Finished Gin is limited to 270 bottles (50% abv) at an RRP of US$49.95.
