Shrubs are a combination of fruit, a sweetener and vinegar. This is made from F-Word Farm grown rhubarb syrup, mixed with F-Word Farm Blueberry Vermouth Vinegar! Rhubarb-y, sweet and tart. Mix with seltzer water for a probiotic mocktail or add some gin or vodka to make it a cocktail. Also good in place of a balsamic vinegar on salads, chicken, fruit or even ice cream.
