Sarawak Liberica comes from Long Banga, a small Kelabit settlement near the Kalimantan border, reached by a two-hour flight in a light aircraft from Miri. The trees are a polyhybrid called Ragi, grown at around 500 metres. Our lot is sealed for thirty-six hours of anaerobic fermentation and then dried as a honey. The cup runs to manuka honey and a florality that is hard to name.
Almost nothing about that sentence is convenient. That is part of why the coffee exists at all.
Getting there
Long Banga sits in the Kelabit highlands, on the Sarawak side of the border with Kalimantan. There is no practical road. You fly from Miri in a light aircraft, about two hours, on a schedule that answers to weather rather than to a timetable.
The estate is a few hectares, at around 500 metres above sea level. Everything that leaves it leaves the same way it arrived, which sets a natural ceiling on how much coffee can ever come out of the place. Scarcity here is geography, not marketing. Where Liberica is sold, and how to recognise a single estate lot.
Five hundred metres is low for arabica and high for Liberica. Liberica is a lowland species by habit, comfortable in heat that arabica cannot survive, and it is rarely grown this far up. The effect is the familiar one at a smaller scale: cooler nights, slower ripening, a denser seed. We would not overstate it. Five hundred metres is not two thousand, and altitude is one variable among several. What altitude does to a coffee.
Ragi, which is not quite a cultivar
The trees are a polyhybrid called Ragi. Polyhybrid means an irregular cross of several Liberica varieties, and the genetics are not stable. One tree does not reliably give the same cup as the tree standing next to it.
In most agriculture that would be a defect. Uniformity is the whole point of a named cultivar. For a coffee sold by the lot rather than by the tonne, the variation reads differently. It is part of why the cup resists a tidy description, and part of why we are slow to print a fixed tasting note and treat the matter as settled.
Thirty-six hours sealed
The cherries are picked ripe and sealed in oxygen-free containers for thirty-six hours before pulping. Fermentation carries on without oxygen, which shifts which microbes are active and which acids and aromatic compounds they leave behind. Then the cherries are pulped and dried with the mucilage still on the bean, which is what honey processing means.
Anaerobic fermentation and honey drying are both amplifiers. Run either one carelessly and you get a muddled, boozy coffee that tastes of the process instead of the place. Run both, on a polyhybrid with unstable genetics, and the margin for error narrows further. Washed, natural and honey, compared.
The cup, and the ten minutes
Manuka honey first. Then a florality that is persistent and slightly strange, and does not resolve into anything you can easily name. Jasmine is close and wrong. It sits over a body heavier than any arabica you are likely to have drunk this week.
It changes as it cools. We give it ten minutes after pouring before tasting critically, because the cup at ninety seconds and the cup at twelve minutes are not making the same argument.
A starting point that works: 1:15, water at 92 °C, a step coarser than your filter default, around four minutes of contact on a V60. If it turns muddy, you have over-extracted. Coarsen and pull the temperature back.
This is not a coffee that flatters a first impression. It rewards a week of repeat brewing, which is an awkward thing to say about a 100g bag that pours about six cups.
What we can and cannot certify
The estate grows without synthetic inputs. It is not certified organic, because certification costs money and years that a few hectares in the Kelabit highlands cannot justify, and we would rather write that sentence than imply a certificate we do not hold. Organic by practice, and what it means.
Green coffee is screened before roasting at independent laboratories accredited to ISO/IEC 17025, for ochratoxin A, aflatoxins and pesticide residues. We publish the reports we hold on the pages of the coffees they cover, as each lot clears. The full standard is written down.
Sarawak Liberica Ragi is the anaerobic honey lot described here. The Malaysia Duo pairs it with the washed Taiping Liberica from Perak, which is the gentler introduction to the species and the more useful comparison. Same species, two islands, two processes. The case for Liberica, in long form.
The short answers
Where does Sarawak Liberica come from?
Long Banga, a small Kelabit settlement near the Sarawak border with Kalimantan, reached by a two-hour flight in a light aircraft from Miri. The estate is a few hectares, at around 500 metres.
What is Ragi coffee?
A Liberica polyhybrid, an irregular cross of several varieties with unstable genetics, so individual trees vary. In specialty coffee that variation is treated as character rather than as a fault.
What does Sarawak Liberica taste like?
Manuka honey, a persistent florality that is difficult to place, and a body heavier than arabica. It changes noticeably as it cools, so it is worth waiting ten minutes before judging it.
What is anaerobic honey processing?
The cherries are sealed in oxygen-free containers for thirty-six hours, then pulped and dried with the sticky mucilage still on the bean. It amplifies aromatics and sweetness, and punishes carelessness.
Is it organic?
Organic by practice, not certified. The estate grows without synthetic inputs but is too small to carry the cost of certification, and we state that plainly rather than implying a seal.
