Halcyon Decaf is Balance Coffee’s single origin Guatemalan from the Rio Azul Cooperative in Huehuetenango, decaffeinated using the sugar cane ethyl acetate process. It is one of the more transparently tested decafs sold in the UK, with Balance publishing third party laboratory results for mould, mycotoxins, pesticides and heavy metals. The cup runs sweet and smooth: milk chocolate, soft caramel, and a quiet almond finish.
Sugar cane EA is the largest decaf method category in the Decaffeinate directory. Most of it is Colombian. Halcyon is a rare Guatemalan sugar cane EA on the list, which is the specific reason it warrants its own consideration rather than a Colombian alternative.
The sugar cane EA process, briefly
Green, unroasted beans are steamed at low pressure to open their pores. They are then bathed in a solution of water and ethyl acetate for around eight hours, with the solution replaced through the cycle. EA binds preferentially to caffeine molecules and pulls them out of the bean. A second steam evaporates residual solvent before the beans are dried and shipped to the roaster. Typical caffeine removal is 97 to 99 percent. Balance state Halcyon’s residual caffeine is below 0.3 percent of the original caffeine content, equivalent to trace levels.
The ethyl acetate used here is fermented from cane sugar, not synthesised from petrochemicals. That is the basis for the natural label. The functional effect on the bean is the same either way: EA is a solvent. Swiss Water specialists fairly point out the distinction. Where the cup actually lands is a question of lab results on the finished bean rather than process semantics, which is why Halcyon’s published testing carries more of the trust load than the natural framing.
What it tastes like
Chocolate, caramel and almond, in roughly that order of prominence. The chocolate is milk rather than dark. The caramel is soft and sweet rather than burnt. The almond sits in the finish rather than the opening. Body is medium and smooth. There is no fruit, no bright acidity, no top end aromatics that go astray during decaffeination.
The bias of the cup is towards comfort flavours, which makes it forgiving across brew methods. It pulls well as espresso, runs sweet through filter, and holds its shape under steamed milk in a flat white or latte. If you want a decaf that doubles up across a home setup without changing recipe per drink, this is one.
The lab testing claim
Balance test each batch of Halcyon for mould, mycotoxins (Ochratoxin A and Aflatoxin B1 specifically), pesticide residue, and heavy metals. The tests are run by a third party laboratory. Balance make the results available on request.
This is testing commissioned by Balance rather than an independent assessment carried out by Decaffeinate. The honest framing is that Balance publish more substantive lab data on their decaf than almost any other UK roaster, the laboratory has no commercial interest in the outcome, and the results are auditable by anyone who wants to look. If contaminant testing is the reason you are buying decaf, Halcyon is one of the few UK options where the evidence is on the table rather than only implied.
About Huehuetenango and Rio Azul
Huehuetenango sits in Guatemala’s north western highlands. Warm air drifting north from Mexico’s Tehuantepec plains keeps temperatures stable at altitude, with the Cuchumatanes mountain range providing additional shelter from Pacific winds. The microclimate lets growers cultivate coffee between 1,100 and 2,000 metres without the frost risk that would otherwise cap high altitude planting in Central America.
The Rio Azul Cooperative was founded in 1967 in Jacaltenango and has over 200 members. Varieties are Caturra, Bourbon and Catuai, all traditional arabicas rather than rust resistant hybrids. Beans are fully washed before the green is sent for decaffeination. The Guatemalan washed sweetness is what survives the EA process and shows up as the chocolate and caramel in the cup.
Who Halcyon is for
Buy Halcyon if you drink decaf daily, care what is in the cup beyond caffeine, and want published testing rather than a vague clean coffee claim. The sugar cane EA process preserves sweetness well, the origin is genuinely interesting, and the lab data is real.
Skip it if you want the cheapest decent decaf on the directory. Colombian sugar cane EA coffees from other UK roasters have typically retailed at around £12 to £14 with comparable processing standards, and Swiss Water alternatives sit in a similar range. Halcyon’s premium goes on the Guatemalan origin and the published testing. Both are valid reasons to pay it, if you value them.
