Guidi of La Sosta Specialty Coffee tells us what roasting means and what it
takes to be a good roaster.
is the transformation process of a raw material - our coffee bean - into a
semi-finished product that must be finalized by the barista with different
During the roasting
process, coffee doubles in volume, loses moisture and organic material (in fact
there’s a weight loss), changes color and multiplies aromas tenfold. Because inside
a seed there is everything, it’s rich in carbohydrates, fats, acids...and the
heat awakens these components.
with any other fruit - because let’s remind ourselves that the bean is a seed
that is part of a fruit - coffee can be sweeter or more acidic, therefore
having high-quality raw materials is fundamental. Quality allows us to have
better coffee even with the exact same roasting. For example, with La Sosta we
only deal with specialty grade coffees, which means having a very particular
quality of seeds right from the start.
from low-quality beans, with defects or other problems due to travelling etc.,
even with the best roast in the world we’ll never get a good quality product. But
with high quality coffee we can enhance its characteristics and bring out
something unique. But be careful, roasting need to be done well and this is
where the roaster comes into play.”
What skills should a roaster have?
“Being a roaster is a job that
requires a thorough knowledge of the raw material – that is, if you want to do
it right. The roaster to me is a person who knows how to taste coffee, knows
how to recognize its defects and therefore knows what to look for in both the
selection, and during roasting.
The roaster's role also consists in knowing
your equipment well and knowing the guidelines of the roasting process. At the
same time, I always say that the first rule for roasting coffee is: there are
no rules! There are guidelines that if followed allow you to avoid problems,
but if the data, numbers and graphics say that this is the recipe for the
perfect roast, it can still be bad or different from expectations.
So, it is important to know how to
taste, know your equipment, the general guidelines of the roasting process and,
finally, you must have consistency, be repeatable. Because a good roaster is
not just someone who takes the best coffee and makes the best roast in the
world, a good roaster is someone who can bring that same quality over and over
