Can't go wrong with the Signet, especially as good pairing with big and nuanced cigars. It's got a lot of chocolate malt and aged in cured in virgin oak barrels....and you can taste that and a ton of age. Big, rich, viscous, but very nuanced. GREAT spice (nutmeg and huge cinnamon) chocolate, and dried fruit. It's a very special whisky and worthy of special occasions. I don't drink it capriciously, that is for sure.
I just recently got some RA Libano REs and i think this will pair very nicely.
