lighter roast colors, such as those shown in the pictures
of the El Salvador peaberry bean and the Colombia
Armenia bean (both Agtron 58 to 60), generally offer
a much more complex cup profile than the same
coffees roasted to a darker degree, like Agtron 40 or
lower. Additionally, there are some other advantages
of roasting light, like a longer shelf life, less emissions
during roasting and a lower risk of roaster fires.
However, roasting coffee as light as the pictures
indicate is not easy; the roaster needs to follow certain
steps to ensure that the flavor profile of the coffee
is sufficiently developed, without creating sour,
astringent or malty notes, which can potentially be
predominant with under-roasted coffee beans. The
solution to developing proper profiles for lighterroasted
coffee beans is to investigate with each coffee
bean type the appropriate time-temperature pattern.
In the case of the Nicaragua coffee beans shown on
the following pages, we applied a roasting style with
moderate heat supply throughout the roast, which
resulted in a gradual increase of bean temperature.
So, what’s the secret to creating perfect-tasting
light roasts? Are you expecting me to reveal a longhidden
family secret that will propel your business
straight into the ranks of light-roast fame and fortune?
