A pool of chilled Ford’s Gin waits for lips to sip it. But first, we pass it around the table, hovering our noses above the rim of the martini glass and taking giant whiffs of what’s inside. The smell is arresting, intense, clean. Citrus mingled with herbaceous gin—and that’s exactly how it tastes. Clean, citrusy, a little herby, not too gin-y. Its aroma and flavor isn’t brought to you by a lemon peel or grapefruit juice, but something called terpenes.
