Blackberry drink syrup can be added to any drink to jazz it up. Simple syrup is often added to cocktails, but it works great for club soda, iced tea, hot tea, water, lemonade, and many other drinks. Add it to any of your favorite cocktails like a blackberry mojito, spiked blackberry lemonade, blackberry margarita, blackberry whiskey lemonade, or a blackberry Moscow mule.
