The Bourbon Rickey is a historical highball as old as the Hayner Brand. It’s tart, dry, thirst-quenching and surprisingly balanced, even without a dose of sugar to tame the other ingredients.
1 1/2 ounces bourbon
1/2 lime, freshly squeezed
Sparkling water, to top
Fill a highball glass with ice.
Squeeze the lime half into the glass and drop it in.
Add the bourbon and fill with sparkling water.
Stir briefly to combine.
