I started with a classic flavor combination, then lightened it for a refreshing coffee beverage. This cocktail works equally well for a warm summer day or crisp winter evening.
Add ingredients to Collins glass with ice.
Stir ingredients until chilled and frost starts forming on exterior of glass (approximately 20 - 30 stirs).
Top with soda water.
Lightly stir drink again to mix (approximately 5 stirs).
Express orange peel over top of drink, run peel around edge of glass, and garnish with an orange twist.
