Flavor concentrates are a great way to add flavor to your drinks without adding calories. They can be mixed with alcohol or added directly to non-alcoholic drinks, so they're perfect for both the cocktail enthusiast and health-conscious person alike.
You can use flavor concentrates in cocktails by mixing them with alcohol, then straining out the solids before serving. Or you could simply add them directly into your favorite drink recipe that calls for syrup or simple syrup (like lemonade).
