Natural Flavouring. We are proud to carry the finest natural flavourings on the market. These alcohol-based flavours will mix easily with your beer, wine or cider without separating. Each flavouring is packed in a 4 oz. bottle. The recommended usage for beer is on the label. For wine or cider, we recommend adding to taste – we often find a half bottle is sufficient. We’re more than happy to add any of these flavours to any U-Brew products you make with us too!
