The hunt for rare varieties

Why we built ESPRĒN around the coffees most roasters won't bother with — and what "rare" actually means in a cup.

The shape of the global market

There are roughly 60 species of coffee. Two of them — Coffea arabica and Coffea robusta — account for almost everything you've ever drunk. Within arabica, three or four cultivars dominate the global crop: Caturra, Catuai, Bourbon, Typica. They yield well, transport well, ripen on a predictable schedule. They feed the world.

And they make perfectly good coffee. We're not against them. But there is a quieter universe behind them, and that's where ESPRĒN lives.

What "rare" means

A rare varietal is one of three things:

Genetically scarce — cultivars that exist on only a handful of farms in the world. Geisha was almost extinct in the 1990s. Sidra was a regional curiosity until five years ago. Pink Bourbon's commercial story is barely a decade old.

Geographically specific — cultivars that thrive in a microclimate so particular that moving them anywhere else dilutes them. Kenyan SL28 grown outside Nyeri tastes nothing like SL28 from Nyeri. Ethiopian Heirloom varietals from Yirgacheffe are unlike Heirlooms from Sidamo, even though they're nominally the same plant.

Process-led — some lots are rare not for what they are but for what was done to them. A 19-day natural ferment with the cherry intact, dried on raised beds in volcanic shade. A honey process at altitude that took weeks to dry properly. These are agriculture as craft, not industry.

Why we bother

Common varietals taste like coffee. Rare ones taste like specific things. Bergamot. Stone fruit. Cocoa nib. Peach. Blackcurrant. Jasmine. Honey. Brown sugar. Some of these descriptors people roll their eyes at — fair enough, before they've had the cup. They're not poetry. They're what is actually happening in the chemistry of a well-grown, well-processed, well-roasted bean.

If you've never tasted a coffee that surprised you, you've probably never tasted a rare varietal at peak.

What we're not doing

We are not collecting trophies. We don't import lots because they're expensive or because they have a story we can market. We import them because they cup well, because the producers are doing exceptional work, and because the price reflects the labour involved.

We have no interest in being the world's largest specialty roaster. We're interested in roasting a few coffees, very carefully, and putting them in front of people who care.

The four countries we've chosen

Colombia for the structural fruit. Ethiopia for the florals. Panama for the Geisha. Kenya for the structure. Each has its own deeper essay in this Journal — the differences are real, and worth understanding before you choose a bag.
