What are unsweetened, single, flavored extracts called?

The term used to describe unsweetened, single, flavored extracts is "tinctures." Tinctures are typically made by steeping herbs or other plant materials in alcohol or another solvent, allowing the flavors and properties to be extracted without the addition of sugar. This method preserves the natural essence of the flavor while keeping it concentrated and potent, making tinctures ideal for culinary and mixology applications where a pure flavor profile is desired.

This differentiates tinctures from other options. For instance, syrups are sweetened and often thicker, used primarily to add sweetness as well as flavor to beverages or food. Bitters are a type of tincture made specifically with bitter plant extracts and are usually more complex in flavor. Essences can sometimes refer to flavored compounds that may not be pure extracts and often, but not always, contain sweeteners. Thus, tinctures stand out as the option that best fits the definition of unsweetened, single, flavored extracts.
