Homemade Coffee Liqueur
A rich, sweet, and robust homemade liqueur inspired by Kahlua. This recipe combines instant coffee, vanilla, and vodka with a thick syrup base to create a versatile spirit perfect for White Russians or sipping over ice. For optimal depth of flavor, the mixture is aged for several weeks.
What it tastes like
This liqueur has a strong aroma of toasted coffee beans and pure vanilla bean. The taste is heavily sweet with a sharp roasted coffee backbone and a viscous, syrupy mouthfeel from the corn syrup. It finishes with a clean alcohol heat and a lingering sugary coffee bean note.
