Part One covered why Costa Rican coffee tastes the way it does, Part Two how to read the grade and region on the bag, and Part Three how Costa Ricans actually brew it. This part is about the step between the farm and your bag, because Costa Rica changed it more than any other origin.
For most of the twentieth century a Costa Rican farmer sold cherry to a large mill, where it was processed alongside hundreds of other farms' fruit and lost its identity on the way. In the early 2000s families started installing their own wet mills and managing drying themselves. That is the micromill movement, and it inverted the economics: instead of selling anonymous cherry, a small producer could sell a traceable microlot under their own name, control every processing decision, and keep the premium. Coffee Review calls it the backbone of the country's specialty profile, and it is why so many Costa Rican bags name a mill rather than a co-op.
Controlling your own processing is also what makes honey coffees possible, and this is the part worth knowing at the shelf. Honey process means the fruit's sticky mucilage is left on the seed during drying rather than washed off, and the colour names — white, yellow, red, black — are a scale of how much stays on. The more mucilage left, the slower the dry and the more fruit intensity you get in the cup. Black honey sits at the far end.
Costa Rica grows across eight regions from about 1,200 to over 2,000 metres, and Tarrazú scored highest in Coffee Review's 2025 report, with the citrus, floral, crisp-structured profile the region is known for. Worth knowing that the producer base has roughly halved in a decade, to around 25,000 — the ones who remain are largely quality-focused specialists.
A Fellow Espresso Series 1 failed after two days and four shots with a boiler fill error, and the 69-comment thread turned into the question actually worth asking: what happens when a $1,500 machine is sealed and proprietary rather than an E61 you can fix with brass fittings. The dissent matters too — other owners report months of trouble-free daily use, and Fellow has replaced failed machines quickly.
An r/pourover thread laid out the whole water ladder rung by rung with real prices — tap, filter pitchers, ZeroWater, mineral drops, RO systems, TDS pens — and the maintenance each one actually demands. The most-upvoted answer, in a sub full of people mixing their own minerals, was tap water.
Heat suppresses perceived sweetness and flattens flavour separation, so a brew that reads bitter at its hottest and turns sweet a few minutes later is behaving normally rather than badly. The fixes the thread converges on cost nothing: brew into a carafe, choose ceramic over a steel travel mug, and swirl the cup.
One part coffee to two parts milk — half steamed, half foam — with the milk pulled off the heat at the top of the SCA's 50–70°C range before texturing. The counterintuitive part is the coffee: a moka pot or a strong French press rather than a pour-over, because a paper filter strips out exactly the body a cappuccino is built on.
The frequency most guides leave out: daily brewers want a light clean weekly and a deep clean every one to two months, while anyone pulling espresso or running dark, oily beans needs one or two deep cleans a month. Stale oil on the burrs is among the least-suspected reasons a cup slowly goes flat.
Brew hot straight onto ice at a 1:10 ratio, counting the ice as part of the water budget rather than as garnish — that is the number improvised versions miss, and why they come out watery. Three minutes start to finish against cold brew's twelve hours, and it keeps the aromatics a long steep strips away.
Two limited releases built around Coffea excelsa, a species almost nobody outside the trade has tasted: a Quang Tri single origin from Vietnam given a 120-hour anaerobic fermentation and a 30-day slow dry, on sale since 18 August, and Beyond Arabica, an excelsa-and-robusta blend landing 1 September. It is a rare mainstream roaster saying out loud that robusta belongs in specialty.
South India Coffee Company runs a 30-hectare estate in Karnataka and maintains a "Living Germplasm Garden" studying 14 coffee species and hybrids, including excelsa, liberica and four species native to the Western Ghats, hunting for heat- and disease-tolerant varieties. It is a concrete answer to what happens to coffee as it gets hotter, and it names a farm rather than a trend.
Lala skirted South Point on the Big Island on 15 August as a category 1 storm, and while the island avoided a direct hit, the Kaʻū district took the worst of the flooding. As lawmakers approved $6 million in emergency funds, Rep. Chris Todd said the storm "destroyed thousands of coffee plants that washed away down south on the eve of the annual harvest."
Thanks for reading ☕
Three things this week cost nothing: let the cup cool before you judge it, swirl it, and check when you last cleaned your burrs. The water ladder is worth reading precisely because its top answer is the cheapest one. If it was useful, forward this to a coffee-obsessed friend. See you next Thursday.
