Yes and no. Liqueurs are sweetened liquor-based beverages that are usually infused with fresh ingredients. Technically, this blackberry infused vodka is sweetened, but because it is so high in vodka, it would be pretty potent for a liqueur. When I make other liqueurs, I usually infuse the vodka with the fresh element and then create a simple syrup to get the perfect sweetness. For this blackberry vodka recipe, I let the sugar dissolve in the mashed berries before covering them all with vodka. Most accurately, I'd call this a lightly sweetened blackberry infused vodka.
