The Greyhound is the definition of laid-back refreshment—crisp vodka and tart grapefruit juice served simply over ice. It’s bright, zesty, and clean, with a mouth-puckering bite that’s as invigorating as a breezy afternoon. Whether you’re lounging poolside or kicking off brunch, the Greyhound is effortless, easygoing, and just sharp enough to keep things interesting.
