This category includes brewed teas, cold brew coffee, espresso, and related infusions that bring bitterness, tannins, caffeine, and complex aromatic depth to cocktails. They serve as both mixers and flavor modifiers, grounding boozy drinks with earthiness or lending a roasted richness to creamy and spirit-forward builds. Tea and coffee cocktails span everything from the classic Espresso Martini to delicate Earl Grey-infused sours.
