How we craft our Pomelo and Pink Pepper Tonic Water at the London Essence Company: The citrus burst of this refreshingly light tonic is created by blending the fresh zing of a pomelo extract with cold-pressed grapefruit oils. To this, we add the gentle spice of our distilled pink peppercorn essence, created by gently heating the pink peppercorns in water to release the aromatic oils. As with the rest of our collection, this tonic is also light and low in calories, with just a dusting of sugar. The perfect way to enliven citrus forward gins for an added pink lift. The aroma is that of fresh citrus with just a hint of spice. The taste? A refreshing combination of tangy grapefruit notes, a delicately spiced pepper note, and a sharp, citrus, and lightly bitter quinine finish.
