The word tequila, according to the oldest folks in the region, comes from the "Tequileros" tribe that inhabited the region along with other groups in the towns of Arandas, Amatitan as well as Tequila 36 miles north of Guadalajara, the capital of the State of Jalisco.
Now according to legend, an Olmecan woman named Mayahuetl discovered agave juice. Agave ("metl" in her native language) was prodigious; it was used for making a cloth known as ayate and rope. Pulp from its leaves was used to make a papyrus-kind of paper and its thorns were used in sacred rituals for sacrifices to the gods as well as for needles and pins. The uses for metl were numerous and even its bagasse was used to fertilize fields.
Codices say that "Petecatl", Mayahuetl's husband, was the first to use the plant's roots to ferment agave juice and distilled it in a somewhat rudimentary fashion, producing what was referred to as "the delightful drink of the gods, priests, kings and warriors".
The Nahuatl Codices underscore that the Indians knew how to distinguish different kinds of agave since the document itself makes a graphic representation of 9 different varieties.
Besides the extensive variety of agaves, there are different techniques used to turn it into an alcoholic beverage, resulting in a wide array of spirituous liquors made with agave that have totally different traits and in some cases physical appearances. They are given different names: pulque, bacanora, comiteco, mescal, pot mescal and, of course, tequila.

As added information, botanical studies claim that the amaryllidaceous family that includes agaves has 71 genera and more than 600 different species.
The dawn of the XIX century and Mexico's independence marked the beginning of several tequila companies, some of which have survived to the present and bear the name or surname of their founders. These distilleries have kept their original names. Those first traditional taverns have become today's plants or factories. By 1899 tequila production had become one of Jalisco's major industries. With vision and tenacity, Cesar Garcia founded our company in 1943 under the name of Rio de Plata Distillery, now known as Tequilas del Señor, S.A. de C.V.
Tequilas del Señor is one of several companies that make the Mexican spirit par excellence: tequila, with the best blue Weber tequilana agave crops grown and harvested at the exact point of maturation. Its work and notable tenacity are reflected in the high quality of our products under the watchful supervision of the Tequila Regulatory Board.
This is how Cesar Garcia created a tradition of tequila that has been passed down to new generations that have created Tequila Garcia and Herencia in his honor. Therefore, to talk about Rio de Plata Distillery and Tequilas del Señor, S.A. de C.V. is to talk about quality tequila and tequila-based products.
