The cultivation process is the first and foremost link in a chain of events that result in a quality tequila. Siembra Azul prides itself in seeking only exceptional, natural, artisan, premium raw materials. Siembra Azul is cultivated in the Golden Triangle of the Highlands of the state of Jalisco. It is a relatively young region as far as commercial agriculture of agave is concerned, dating back to 1800s. The acidic, iron rich soil is ideal for growing large agave with high sugar content. In a less acid soil, the agave tends to be smaller, with more carbohydrates and a hard fibrous texture. Additional benefits of the Highland terroir include top soil minerals washing down to lower levels where the roots of the plant come to contact with them, enriching its flavor. Furthermore, Highland agave take 7-12 years to mature ( as opposed to the Lowlands 5-8 years maturation), adding complexity and richness to the final product.
