ONE COFFEE. TWO WAYS IN.

Quảng Trị, Vietnam · Natural Process

This Excelsa takes two paths: our roast for your brewer, or green beans for your own roaster. Natural processing dries the fruit around the seed before it’s removed. Origin, process and roast all help shape the cup.

WHAT MIGHT YOU FIND IN THE CUP?

Naomi Joe production-roast notes are coming. Roasting it yourself? Your roast and brewing choices will shape what you discover.

OKAY, BUT WHAT IS EXCELSA?

01

NOT ARABICA. NOT ROBUSTA.

Excelsa is currently treated as its own species, Coffea dewevrei. Older sources often grouped it with Liberica. Another part of coffee’s family to explore.

02

A RARE FIND.

Excelsa has a much smaller commercial presence than arabica or robusta. It’s a coffee many people haven’t had the chance to try.

03

WHAT ABOUT CAFFEINE?

Some tested Excelsa coffees have shown lower caffeine levels. We haven’t lab-tested this lot, so we’re not putting a number on it. This is not decaf.

04

WHY ARE RESEARCHERS INTERESTED?

As coffee-growing conditions change, researchers are studying Excelsa’s potential to give growers more options.

A little more about the name and the research

Naming and classification

Excelsa is currently treated as Coffea dewevrei. Older sources often placed it under Liberica. Botanical naming changes as researchers refine their understanding, so historical descriptions can use a different classification.

Explore Kew’s Excelsa and Liberica research and the 2025 genetic research.

Caffeine: what we can say

Some tested Excelsa coffees have shown lower caffeine levels. Those results are not a measurement of this Quảng Trị lot. We haven’t lab-tested it and are not assigning a caffeine-reduction percentage. This coffee is not decaf.

Climate: potential, not a guarantee

Excelsa is being studied as part of a more diverse future for coffee. That interest does not establish that this particular coffee is drought-proof, disease-proof or has a smaller environmental footprint. We are not claiming quantified water, carbon or other environmental savings for this lot.
