The Perfect Roast
Each
single origin coffee has its own unique characteristic and nuances of
flavor. Bringing them out requires an artful touch, skilled judgment
and well-trained eyes and ears. Subtle variations in the roast time,
temperature and airflow allow the roaster to take each coffee to its
peak of flavor. It's a slower, more demanding roast that stops at the
exact point at which the sour-tasting acids have been roasted out, but
bitter flavors haven't appeared. That gives the beans a deeper,
heartier flavor and a rich chestnut color, as opposed to the cinnamon
brown color common with commercial roasts.
For
the final step in the roasting process, we air cool our beans (instead
of the money saving quench method used by commercial coffee roasters).
Then, to ensure freshness, we hand pack them within two hours in
special nitrogen flushed valve packages that let gases from the beans
escape without allowing air to reach them.
We
roast coffee to bring out the best flavor characteristics in each bean,
and we continually work to upgrade the quality and consistency of
coffee. Our roast is darker than the average roast-it is much darker
than commercial coffee, and considerably darker than most of our
specialty coffee competitors. We believe that our roast is the best way
to harmoniously change and meld together the hundreds of chemical
compounds that make up a coffee bean, turning the inert looking green
pebbles into rich, chestnut brown beans packed with flavor.
What
actually happens to the green coffee is fascinating. The beans are
introduced into a large, rotating drum, which is heated using gas.
After about 5-7 minutes, a lot of moisture is driven off, and the green
beans change to a lively yellow color, and smell like buttery
vegetables. The coffee continues to darken and lose moisture, and then,
at about 8 minutes, "first pop" occurs. At this point, the coffee pops
like popcorn, and nearly doubles in size.
The
beans continue to darken, and more moisture is lost, and a few more
minutes, oil becomes visible on the surface of the bean. Sometime
between 11 and 15 minutes, depending on the coffee and other variables,
the coffee beans pop again ("second pop"); then the beans are nearly
ready. From this point on, it is up to the master roaster to make the
decision as to when the beans are ready. The decision is made as to
when the coffee beans are ready. The door of the roaster is opened and
into the cooling drum emerges a hypnotic swirl of smoke and chestnut
brown coffee beans, still completing second pop, and giving off
tremendous amount of heat and energy.
This
roasting method is not cheap to produce. All that moisture loss means a
lot of weight loss-about 22% for most of our coffees, and nearly 25%
for French Roast. Most commercial coffee loses only 10-14% of it's
weight during roasting but we roast to please the senses and not save a
few cents.
