Bitter Green

Chill a martini glass by filling it with ice water while you prepare the cocktail.

Combine the Irish whiskey, dry vermouth, herbal liqueur, Fernet Branca, rich simple syrup, and peach bitters in a mixing glass filled with ice.

Stir the mixture thoroughly until well chilled.

Discard the ice water from the martini glass and strain the cocktail into the now-chilled glass.

Express the oils from a lemon peel over the drink and use it as a garnish by placing it on the rim of the glass.

Serve and enjoy your expertly crafted Bitter Green.
