Coffee Beans and Origins

Where coffee grows, how the cherry becomes a bean, and what to buy.

Coffee is the seed of a fruit. A coffee cherry contains two flat-sided seeds, and everything between the tree and your grinder — picking, pulping, drying, hulling, sorting, shipping, roasting — is processing that seed without spoiling it.

Nearly all of it happens in the Bean Belt, the band between roughly 25°N and 30°S. Brazil alone produces around a third of the world's coffee. These guides cover the geography, the processing methods that shape flavour, and how to buy beans that were roasted recently enough to taste like anything.

Common questions about beans & origins

What is the difference between arabica and robusta?

Arabica is the more delicate species, grown at altitude, with more acidity and aroma and roughly half the caffeine. Robusta is hardier, cheaper, higher in caffeine, and tastes more rubbery and bitter — which is why it turns up in instant coffee and in Italian espresso blends for crema.

Is coffee grown in the United States?

Yes, in Hawaii and Puerto Rico, and on a small commercial scale in California. Volumes are tiny relative to world production, and the labour cost is why Kona coffee is priced the way it is.

What does single origin mean?

That the coffee comes from one identifiable place — one country at the loosest, one farm or lot at the strictest. It is a traceability claim, not a quality guarantee, though roasters usually reserve it for coffees worth tracing.
