This whiskey demonstrates the impact that wood can have on the flavor and complexity of a whiskey. Jameson Round is still a blend of pot and grain whiskey, but this time some of the grain whiskey matures in virgin American oak barrels giving additional vanilla sweetness. A pot of still whiskey matures in American barrels, sherry butts and Madeira casks. This combination of cask types brings a variety of flavors showcasing the impact on the whiskey of the different woods varying from leather to dried fruits to ripe fruits.
