noblesse oblige

1 1/2 oz Grosperrin VSOP Cognac (Courvoisier VS)
1/2 oz Mezcal (Fidencio)
1/3 oz Pedro Ximenez Sherry (Oxford 1970)
1/3 oz Byrrh Quinquina
1 dash Chocolate Bitters (Bittermens Mole)

Stir with ice, strain into a cocktail glass, and garnish with orange oil from a twist.
For a nightcap two Fridays ago, I selected Tom Sander's 2012 World's Best Cocktails book in search of inspiration, and I landed on the Noblesse Oblige. This Cognac over mezcal number was created by Nicolas de Soto at the Experimental Cocktail Club in London's Chinatown, and the format reminded me of the Chancellor and quinquina-containing riffs like the Administrator. Once prepared, the Noblesse Oblige called forth orange, raisin, and smoke elements to the nose. Next, a rich grape sip bowed to Cognac, smoky agave, and dried fruit flavors on the swallow with a quinine and chocolate finish.
