GRUMPY'S VODKA is mashed from Non-GMO white corn, with malted millet and malted barley, to bring out the sweetest flavors of the corn. After fermenting our mash for about a week, we distil our Vodka through multiple fractional columns. Through this process, our Vodka retains its sweet, rich flavor, while making it incredibly smooth. Perfect for a Martini, or just sipping straight!
