Reported material/flavor associations are not isolated causal studies. Copper-neutrality and agave-starch descriptions simplify chemistry. Long fermentation is not unique to mezcal or necessarily superior. Bubble observation is not a precision proof assay; stated legal requirements are source-era summaries.
