Named to commemorate the final year of the Mexican Revolution 1921 Tequila is made from 100% Agave cultivated in the Highlands of Jalisco, Mexico. The distinction between tequila made from highland agave versus tequila made from lowland agave is important because agave grown in the highlands tends to carry a different flavour profile into the final tequila than lowland tequila. Highland tequila tends to have more sweet fruity citrus flavours and perhaps a touch more hot pepper in the finish.
Although I could not find direct information on the 1921 Tequila website regarding the exact distillery which produces this agave spirit, I did notice that the identified NOM on the bottom of the label is 1535. This NOM identifier is required by the Mexican Government to be placed on the label of each bottle of tequila to verify that it is produced legally from agave sourced in the Tequila region of Mexico. Each distillery has its own NOM, and thus we can trace the distillery of origin. In this case it is Destileria Morales, S.A. de C.V. which is located about 100 km east of Guadalajara in Arandas ( a municipality of the Altos Sur region of the state of Jalisco).

I should note the 1921 Tequila Brand has moved production to Casa Tequilera de Arandas, S.A. de C.V. (NOM 1499) which is located about 7 km east of Arandas ( a municipality of the Altos Sur region of the state of Jalisco). Although the overall character of the tequila should remain consistent, there may be subtle changes in the overall flavour profile due to this move.

Camarena is a relatively new tequila brand launched in 2010 by six generation tequila producer, Familia Camarena.
