Brothership Irish Whiskey- ABV: 45% Proof: 90. New Liberty partners with Rob Cassell’s distillery in Ireland, Connacht Whiskey. They source a 10-year-old Irish malt whiskey and blend it with a 10-year-old American whiskey. This blend beautifully brings together the best of both worlds of Irish whiskey and American whiskey. On the nose you might pick up some black licorice and straw. The palate will provide a lighter whiskey with a touch of caramel, a little grass, plus some oak.
