I am going to try to find this on my cruise. The Hennessy Pure White Cognac is a very interesting one. First of all one has to comment on the very simple, Cognac-unlike, almost modern 70 cl bottle. The spirit is at ABV.
Pumpkin Mudslide Equal parts Pumpkin Spice Schnapps or Fulton's Harvest Pumpkin Pie Cream Liqueur Kaluha Vanilla Vodka Splash of milk (however much or little as you like) Shake with ice and enjoy! The first one I tried had Pumpkin Spice Schnapps.
