Tobacco + caramel + vanilla = perfection. At least, that is what fans of RY4 keep saying, and we agree with them! RY4 may be the ideal tobacco flavor for inclusion in tobacco mix, so grab a bottle or two and try it out. RY4 is great and just as great when its flavor is complemented with other strong tobacco flavors.
Note: this flavor is highly concentrated. Start at 1%, and then adjust to taste.
