Coffea Diversa — A Living Coffee Library
Coffea Diversa is unlike any other coffee farm in the world. Founded by botanist and coffee researcher Willem Boot, it functions as a living genetic library — home to over 1,000 coffee varieties from across the globe, cultivated and studied on a single estate in the highlands of Costa Rica and Guatemala.
The farm's mission is the preservation and exploration of coffee biodiversity. Varieties are grown side by side under controlled conditions, allowing for direct comparison of genetics, processing, and terroir. The result is coffees with documented provenance, exceptional genetic purity, and extraordinary cup quality.
The Corona selection is one of Coffea Diversa's most celebrated Geisha expressions — grown from carefully selected genetics and processed with the precision that defines the farm's approach. Each lot is small, traceable, and harvested at peak ripeness before undergoing meticulous washed processing.
Washed Process
In washed processing, coffee cherries are pulped and the fruit mucilage is removed through fermentation and washing before the beans are dried. This method produces a cleaner, more transparent cup that highlights the coffee's intrinsic variety character and terroir rather than processing-derived fruit notes.
For Geisha, washed processing is the traditional benchmark — it removes all distractions and lets the variety's extraordinary floral aromatics, refined acidity, and tea-like clarity speak for themselves. Coffea Diversa's meticulous water management and fermentation control ensure exceptional consistency lot to lot.
Brewing Recommendations
This washed Geisha is best brewed with methods that emphasize clarity, delicacy, and floral aromatics:
Pour-over (V60, Origami, Kalita Wave)
Chemex for a clean, classic expression
Flat-bottom brewers for balanced sweetness
Brew at 200–205°F with a medium-fine grind. Serve in a tulip-shaped cup or wine glass to fully experience the aromatic complexity.

What Is 100% Kona Coffee?
100% Kona coffee refers to coffee grown exclusively in the Kona district of Hawai‘i Island — a small, volcanic region
along the western slopes of Hualālai and Mauna Loa. The combination of mineral-rich soil, afternoon cloud cover, and gentle trade winds produces one of the world’s most distinctive coffee terroirs.
To be labeled “100% Kona Coffee,” every bean must be grown within the Kona district and meet strict Hawai‘i grading quality standards. Kona coffee can be made from different arabica varieties, but Kona Typica — a heirloom lineage — remains the region’s most common and traditional cultivar.

About Kona Coffee
-
Kona coffee grows on the volcanic slopes of Hawai‘i Island, where mineral-rich soil, afternoon cloud cover, and slow cherry maturation create a naturally sweet and balanced cup. Our Kona Classic Medium is sourced from high-elevation farms and hand-harvested for clarity, smoothness, and elegant sweetness.
-
Yes — this roast is Authentic Kona coffee made exclusively from North Kona district-grown coffees, never blended. Our Kona coffees comes from small farms at the highest altitudes in the region.
-
Medium roasts highlight Kona’s signature profile: gentle sweetness, soft citrus, toasted almond, and milk chocolate. The result is a balanced, approachable cup ideal for everyday brewing.
-
This coffee shines in pour-over, drip, and French press. Use filtered water just off the boil and a medium grind for maximum clarity and sweetness. If you are looking for a Hawaiian coffee for espresso use we recommend our Hawai‘i Island Blend
-
Kona is the highest labor cost coffee region in the world. Wages for farm workers here are 15-20x higher than almost all other coffee producing countries. Limited and expensive land, hand-picking, and high production costs create a naturally small supply each year — especially from high-elevation farms like those we partner with.

Coffees
-
Our commitment to you is to serve exceptional, fresh-roasted coffees. And part of being exceptional means roasting before the flavors inherent in the green bean begin to fade, which happens over time.
Like apples and pumpkins, coffee is a seasonal agricultural product and each country has a different harvesting cycle in which coffees are at their peak. If we were to insist on serving a single origin all year long, the flavors in that coffee would be noticeably better one half of the year over the other. So the reason you no longer see that coffee you loved is because the optimal season has passed. For more on seasonality in coffees, see this blog post here.
-
Hopefully so. If it was a popular product or we receive customer requests, we will make every attempt to bring it back. However, please note that coffees from a certain producer may not taste the same year after year.
If you loved a coffee and no longer see it listed, shoot us an email and ask us what is similar. We’d be happy to provide a personal recommendation.
-
We aim for balance and completeness along with differentiation and distinction. You shouldn't need to be a professional coffee taster to tell the coffees a part, so, when we’re selecting coffees, we want them to be distinct from each other.
We avoid ”one-trick pony” type coffees, such as Ethiopians with great aroma but no body or acidity, or coffees with good aroma and acidity but lacking sweetness. These elements, which are often reflections of the growing conditions, are harmonized through good roasting.
And, obviously, defects — even subtle defects — influence our selection. Since we live and work at origin, we’re sensitive to coffee defects like “past crop”, pulpy, and naturals that border on over-ferment. With naturals, we’ll only carry these when great examples are available.
-
Our perspective on roasting is similar: we seek balance and distinction. To expect that a coffee is “best” when roasted to some pre-determined degree (i.e. only light roasting or only dark roasting) is analogous to thinking that each person would look best in the same outfit, or each coffee should be grown in the same way. We believe it’s our job to discover the roast degree which best highlights outstanding qualities in each coffee.
