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.

Chimo!
The 1800 Tequila brand is owned by the Beckmann Family, who also own the Jose Cuervo brand. And indeed, according to the nom identifier upon the bottle (Nom 1122 CRT) the brand is produced at the same facility, the Casa Cuervo, S.A. de C.V. (established in 1758) which is located in the central lowland tequila region of Jalisco Mexico.
The identified NOM on the back label of the bottle is 1449 CRT. 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 by researching this we can discover exactly which distillery produces each brand of tequila. It came as no surprise to me to discover that the Don Julio Brand is produced at the Don Julio Tequila Distillery located in Atotonilco, Jalisco. This distillery also produces the 3 Magueyes tequila brand.
El Jimador Tequila is owned by Brown-Froman. The Brand is produced thirty miles from Guadalajara, in the state of Jalisco, in the town of Amatitan, at Brown – Forman Tequila Distillery Mexico, S. de R.L. de C.V. which is also referred to as Hacienda Herradura. The Hacienda also produces the more premium Herradura brand as well as Suave 35 and Antiguo. The Jimador tequila is named to pay homage to the jimadors who harvest agave. After it is harvested, the agave is cooked in clay ovens. The juice is extracted after cooking using steel bladed shredders after which it is distilled on old copper pot stills.
