KOVAL Four Grain is distilled from a mash bill of oat, malted barley, rye, and wheat. This whiskey is aged in heavily charred new oak barrels from Minnesota and bottled single barrel at 94 proof, using state-of-the-art technologies to achieve precise consistency and quality. The four grains define its depth with a banana nose, creamy palate, and spicy finish. Perfect sipped straight or with a single sphere of ice.
