Overview

Coffea eugenioides is one of the two parent species of Arabica, responsible for the natural sweetness, low bitterness, and gentle florality that define modern coffee. Today, it is cultivated by only a handful of farms worldwide, almost exclusively for conservation and small experimental releases.

Eugenioides Rey is a natural large-bean mutation grown at Coffea Diversa in Costa Rica. The mutation produces the largest beans of any known coffee species and an extraordinary ~52% natural peaberry yield—a biological anomaly rarely seen in coffee.

This is also the first honey-processed Eugenioides we have encountered, adding depth and texture while preserving the species’ defining softness. In the cup, Eugenioides Rey is more Arabica-like than any other coffee species we have tasted—immediately familiar yet unmistakably distinct, with exceptional sweetness, clarity, and elegance.

This release offers a rare opportunity to taste coffee at its genetic origin—ancestral, refined, and quietly remarkable.

Process & Roast Style

This lot is honey processed, preserving fruit sugars during drying to enhance sweetness and mouthfeel.

Roasted light, the profile is intentionally restrained to protect the species’ natural character — emphasizing clarity, gentle acidity, and a seamless, honeyed finish rather than roast influence.

Cup Profile

Expect a remarkably soft yet expressive cup, with flavors of sweet black plum, lime zest, cacao, and stevia-like sweetness. Acidity is bright but never sharp, carried by a velvety body and a long, lingering aftertaste.

This is not a loud or aggressive coffee. Its power lies in finesse, balance, and depth.

Who This Coffee Is For

Collectors and experienced drinkers exploring rare coffee species

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.

Kona Coffee FAQs-Roasting, Sourcing, and Shipping

Find answers to common questions about our 100% Kona coffees, roasting schedule, shipping times, and sourcing practices.

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.

We roast and fulfill all of our coffee orders in Hilo, Hawai'i.
We roast in small batches using a Diedrich IR12 roasting machine.

We source an array of the top specialty coffees worldwide that appeal to an array of different palates.

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.
