Old Line Port Cask Finished American Single Malt is part of the Baltimore distillery's Double Oak Series, matured first in new American white oak before a secondary rest in seasoned tawny Port barrels. Bottled at 100 proof, it layers Old Line's malt-forward house style with the rich, wine-cask complexity that defines the series. We love how the Port finish folds dark cherry and apricot warmth into the malt without overpowering its elegant base, making this a rewarding pour for craft single malt drinkers.
