The Conference is a modern cocktail that was created by Brian Miller at Death & Company in New York City, New York. It uses the classic Old Fashioned template of a spirit, simple syrup, bitters, and citrus, but this version calls for four different spirits as its base—rye, bourbon, apple brandy, and Cognac. It's also named for the concept used in the drink of different elements coming together.
Add rye, bourbon, apple brandy, brandy, Demerara syrup, aromatic bitters, and chocolate bitters to a mixing glass.
Fill mixing glass with cubed ice.
Using a bar spoon, stir for 30-45 seconds until well-chilled and slightly diluted.
Add a clear ice cube to a lowball glass.
Using a julep strainer, strain into lowball glass.
Garnish with orange twist and lemon twist.
