From
the Rich Soils of Jalisco...
Tequila
is predominately produced in the western Mexican state of Jalisco,
near the town of Tequila. The hills of the Jalisco area are
covered in agave farms. Over 100 million agaves dot the 100
thousand acres dedicated to growing the plants, that in turn
produce 50 million gallons of tequila each year. About 40% of
the tequila produced in Jalisco is exported. The production
of tequila is a way of life in Jalisco and the surrounding areas.
More than 30,000 people are employed as farm workers, eight
thousand more in various other capacities, and the university
even offers courses in tequila engineering.
There
is considerable debate over which region in the State of Jalisco,
and which method of distillation, produces the best tequila.
Most of Jalisco is a high plateau, about 7,500 feet above sea
level. The soil is red with rich minerals at the highest points,
and black in the valleys. Some contend that the best agave is
grown on the slopes of the extinct volcano beside the town.
Others, from the highlands region, where the agave grow very
large. Highland distillers tend to use more traditional production
methods to manufacture smaller quantities of tequila, whereas
those closer to town produce export product made in a more modern
facility. Up until 20 years ago, by law, all tequila had to
be made in Jalisco. Still, only two distilleries are in business
outside the state.
Tequila
is made from the center of the blue agave. The blue agave is
part of the lily family, not, as commonly thought, the cactus
family. It has a lifespan of 8-14 years. The plants are grown
in cultivated orchards known as potreros (pastures). They are
grown from shoots taken from the four to six year old adult
plants at the start of the rainy season. Typically, the shoots
are left to dry out in the field for about a month, then planted
in a nursery until transferred to the field one year later.
The agave
plant takes about eight years to mature to the point where it
is suitable for fermentation. Sometimes, it is left for up to
12 years. For instance, Herraduara uses only plants that are
10 years old or older. The more mature the plant, the better
the natural sugars. It is routinely pruned to encourage the
pina (center) to grow. Most fields are hand grown and cultivated
by traditional methods which have been passed down for generations.
The agave depends completely on rainfall for moisture, as the
fields are not irrigated.
A
Time to Harvest...
The
heart of the agave, which resembles are large pineapple or pinecone,
is that which is utilized for producing tequila. At maturation,
it weighs from 80 to 300 pounds. The largest pinas ever grown
in the highlands have weighed up to 500 pounds. The agave produces
a 15 foot tall shoot topped with pale yellow flowers. The stalk
itself is picked and eaten as a vegetable from agave that grow
in the wild. The cultivated plants are not allowed to grow a
stalk, because it deprives the plant of nutrients. The ripened
pina develops a maroon tinge and red spots on the leaves, and
also begins to shrink.
The pina
is cut from its stalk for harvesting. The 6 to 7 foot spiky
leaves are cut away from the heart using a sharp, long-handled
tool called a coa. Some fields have three generations or harvesters
working them, as this is a skill passed from father to son.
An experienced harvester can gather more than a ton of pinas
per day. Harvesting is done year round, as the plants mature
at different rates.
After
harvesting, the pina's are taken to a factory. Traditional distillers
(tequilleros) soften the pinas in steam rooms or slow-bake ovens
for 50-72 hours. The traditional oven is called a horno- which
is where Sauza's name Hornitos orginates from. The agave process
its natural juices during baking. The process also softens the
fibres and keeps the agave from caramelizing and adding a bitter
flavor. Natural flavors are preserved through this method. Some
large distillers cook their pinas in pressure cookers in a single
day. Most, but not all traditional distillers allow the pinas
cool for 24-36 hours, and then mash them separate the pulp from
the juice. Some keep them together during fermenting. It takes
about 7 kilograms of pina to produce 1 litre of 100% agave tequila.
The average pina makes 60-100 litres. Smaller distillers often
purchase agave syrup, rather than involve themselves in the
entire process.
Liquid
Gold...
Originally,
the pinas were beat with mallets to break them up after they
were soft and cool. They were moved to a giant grinding wheel
which was operated by mules, oxen or horses. Modern distilleries
use a mechanical crusher to process out the waste, which is
then used for fertilizer. The pinas are then minced and strained
to remove the juices (called aquamiel or honey water), and mixed
with water in large vats. Then, the liquid is sprinkled with
yeast. The mosto is left to ferment in wooden or stainless steel
tanks. Naturally, the process takes 7 - 12 days, but modern
plants add chemicals to accelerate the process toward completion
in as little as two days. Longer fermentation results in a more
robust body. Brown Sugar cones or cane are sometimes added to
speed fermentation when less plants, or immature ones, are used.
These tequilas are called mixto, and are not labeled 100% agave.
The result
of fermentation is a liquid with about 5-7% alcohol. This liquid
is distilled twice in traditional copper pot stills called alambiques,
where the best are said to come from Tomelloso, Spain. In modern
distilleries, it is done in stainless-steel column stills. Distillation
takes four to eight hours. The first, called the ordinario,
takes about 1 1/2 hours, and is 20% alcohol. The second takes
about three to four hours and is about 55% alcohol. The resulting
liquid has three components. The cabeza (head) has more alcohol
and unwanted aldehydes, and is discarded. The middle section,
El corazon, (the heart), is the best part and is saved for production.
The end is the colos, (tails), and maybe recycled into the next
distillation to make it more robust.
All tequila
is clear after distillation. The color comes from aging in wooden
barrels, or from adding caramel (in mixtos only). Before bottling,
most tequila is filtered. Most distillers add water to bring
the alcohol content down to 40%. Reposado and anejo tequilas
will be stored in wooden casks in warehouses. Now that premium
aged tequilas are so fashionable, some distillers are aging
them longer in oak barrels to absorb the maximum coloring. While
some distillers may place additives into the tequila to give
the impression of age, distillers like Centinela, disdain such
a practice. Tequila placed in a new barrel vs. an older one
can affect color as well. Therefore, the color is not always
an accurate reflection of age or quality.
The final
product is usually blended with other barrels of a similar age
to create a consistence of taste and aroma. The Tequila Regulatory
Council oversees the production to ensure that standards and
quality control are in place and met. The resulting mix is bottled.
All 100% agave tequilas must be bottled in Mexico. Only mixto
tequila is allowed to be shipped in tanks and bottled outside
the country.
A
Proud Legacy...
There
are all too few instances left where the ways of days gone by
are still carried on with such dedication and meet with such
success. It is no wonder that the sight, taste, and smell of
a well bottled tequila conjurs up not only appreciation for
the final product, but also for all the skill, labor and care
that stands behind the proud tradition of this most unique product
of Mexico.
