The chicago is a classic sparkling cocktail from the pages of the venerated savoy cocktail book. Traditionally, its topped with champagne. You can use any sparkling white wine you like, but be sure it isnt too sweet. The chicago is often served with a sugared rim, which was common to drinks of the era. We like the dry, boozy quality of the drink as-is, so we only rim half the glass if we even bother with it at all.
