This page lists the authoritative sources Crema relies on to
fact-check the claims in its articles. It applies to every article on this
site, in combination with the Editorial
Policy.
Standards we hold sources to
A source counts as authoritative when it meets one or more of these criteria:
-
It is a standards body, professional association, or government agency
with recognized authority in the subject. -
It is peer-reviewed research published in a reputable venue.
-
It is a primary source — a rulebook, a piece of official documentation,
a designer or maker’s own published statement, a regulatory filing. -
It is an established, editorially-independent trade publication with a
track record of accurate reporting in the field.
Individual bloggers, forum posts, and unverified social-media claims are not
treated as authoritative on their own. They may be cited when attributed
transparently (“a user on the r/coffee subreddit reports…”) but do
not carry the weight of the sources listed below.
Authoritative sources for home coffee brewing
-
Specialty Coffee Association (SCA) — cupping protocol, brewing standards, the flavor wheel, water chemistry guidance.
-
World Coffee Research — varietal reference, cultivar characteristics, agronomic research.
-
James Hoffmann (World Barista Champion 2007) and Scott Rao (author of Everything but Espresso and The Coffee Roaster’s Companion) — authoritative practitioner sources on brewing technique and roasting.
-
Peer-reviewed coffee chemistry and sensory research — when a claim about extraction, chemistry, or physiology warrants a citation.
What we do when sources disagree
If two authoritative sources disagree on a factual point, the article says
so explicitly, names both positions, and explains which one we’re following
and why. We do not launder disagreements into a single-voice answer that
pretends the disagreement doesn’t exist.
What we do when we cannot find a source
If we cannot find an authoritative source for a claim, we either drop the
claim, mark it clearly as speculation or personal observation, or replace it
with a weaker claim that we can source. Our editorial process treats
“we’re not sure” as an acceptable answer; “we sound sure but
made it up” is not.
