Extracts and aromatic waters — such as vanilla extract, rose water, and orange blossom water — are potent, highly concentrated flavor agents used in small quantities to introduce nuanced aromatic and flavor notes to cocktails. They act as invisible enhancers, weaving in floral, herbal, or sweet complexity without adding significant volume or alcohol. These ingredients are particularly valued in craft cocktail culture for their ability to evoke specific aromas and bridge flavors in a subtle yet impactful way.
