Emerald is a whiskey-based cocktail that is often classified as a slightly altered version of the classic Manhattan. The cocktail combines Irish whiskey, sweet vermouth, and bitters. To make the cocktail, the ingredients are stirred in a mixing glass with ice.
The combination is then strained into a chilled glass. This cocktail is usually served in a coupe, and it is often garnished with an orange twist. As evident from the list of ingredients and the name (Emerald is a colloquial name used for Ireland), this cocktail was thoroughly inspired by Ireland.
