Composition
Producer published figures · delmaguey.com/mezcal/vida (label strength, verified via retailer listing). Del Maguey Vida is taken as the reference bottle: it is the mezcal this drink's originating bar's recipe names by name, bottled at 42% alc./vol. (84 proof). The producer's own page returned a 403 on fetch, so the figure is cross-checked against a retailer's product listing quoting the same label strength rather than against the producer's site directly. No sugar or nutrition figure is published for it; mezcal is an unaged, unsweetened agave distillate, so sugarGPer100 is stated as 0 rather than omitted, but no fuller nutrition panel is available and none is estimated here. Density has no measured source and is taken from the density-classes.json 'spirit-40' class.

Tequila: Removes the smoke rather than replacing it; a drink built to carry a trace of mezcal alongside another spirit reads plainer and cleaner with tequila in its place.
A general substitute is a browsing aid rather than a drink-specific claim. Where a particular drink has a substitution worth making, it says so on its own page and recomputes the spec for it.
