I tried the above version and a second version with Luxardo Bitter Bianco instead of dry vermouth. The original was somewhat tepid, as already mentioned here, but with the Bitter Bianco it was quite interesting. I will try 1 oz Bitter Bianco instead of 1.5 oz the next time...
It depends on the mezcal you use; more mineral flavor or more smokey...
I think this can be a excellent cocktail!
If done with a quality pear liqueur the pear flavor is there but not overpowering.
