Quiquiriqui Espadin mezcal was designed with the bar in mind from the ground up. The maestro mezcalero, Carlos Mendez Blas, gets more volume out of each distillation run by making a wider cut and clearly is balancing that with a lower ABV without sacrificing too much flavor.
The larger liter bottle size is deceptive, it’s not designed to be different, it’s designed for ease of use and economy. It has a screw top for quick access and the size means it’s cheaper to ship which keeps the per bottle cost down. The ABV is tuned to 41%, just above your standard margarita tequila but with masses more flavor.
