Celtic - Irish Oak Whiskey Red Ale. Lough Gill Brewery embarked a journey in uncharted waters, taking such an historical style like a Red Ale, making it stronger in alcohol and body and before packaging infused in dark roasted oak chips that previously were soaking in Irish Whiskey for a number of weeks. This blend of toffee notes, caramel malts, Woody flavours from the oak and the embracing intensity of Irish Whiskey make Celtic a real new adventure in your glass.
