The rickey is a classic highball cocktail made with gin or bourbon, lime juice, and carbonated water. It was invented in Washington D.C. at Shoomaker's bar by bartender George A. Williamson and named after the Democratic lobbyist Colonel Joe Rickey. Its popularity grew when made with gin instead of bourbon a decade later.
The cocktail is clean, sharp, and refreshing and is always served in a highball glass. Optionally lime wheels are used as a garnish and can be added sugar.
Fill a highball glass with ice and combine the gin and lime juice.
Garnish with lime wheel.
