Inspired by founder David Souza’s mother’s sweet potato squares recipe, Corbin Cash Barrel Reserve Sweet Potato Liqueur is our most unique creation. Made from 100-percent-estate-grown California sweet potatoes, it is distilled at lower proof to retain more flavor and aged in custom charred American white oak for up to 4 years. A mild blend of brown sugar, spices and extracts introduces an array of aromas, flavors and texture that make this a standout in our portfolio.
