The whiskey has a star bright aroma of peaches, blackberries, caramel corn & toffee, which leads to a palate marked by burnt oak, red wine, cinnamon spice & dark & dried fruits. The finish is long & dry, with lasting notes of sweet tobacco, cornbread & baked apples. The Jeffersons Reserve Groth Reserve Cask Finish has first been aged in new American oak for six years. From there, it was finished in Groth Cabernet Sauvignon barrels for a further nine months. The nine months the Bourbon spends in these special barrels gives Jeffersons Groth Reserve Cask Finish Bourbon Whiskey its unique & robust characteristics. Groth is a well respected winery out of Californias Napa Valley, & its cabernet in particular, which is thus likely why those behind Jeffersons turned to them to get hold of the wine casks for this special release.
