Opened a bottle of Don Amada Mezcal and tried this cocktail from their website. This has the Mezcal Rustico from them, green Chartreuse and simple syrup. (The original recipe by Polina Kharmas called for demerara syrup which is similar to simple syrup except it is made from something similar to brown sugar.

Liked the strong effect of chartreuse on the smoky mezcal.
