1 ounce gin -- a nice herbal one (I use Vikre Distillery Cedar) 1 ounce Aperol 4 ounces chilled porter-style beer orange wedge
Stir the gin and Aperol with ice until chilled but not fully diluted (about 30 seconds, depending on the size of your ice cubes), strain into a glass, top with porter, and squeeze in the orange wedge.
