Midnight Bloom Coffee

Circasia Galaxy Hops Mossto Gesha

Mon, 01 Sep 2025 11:00:00 -0800

Edwin Noreña is one of a handful of Colombian producers treating fermentation as a controllable variable rather than a step to get through. This lot is the clearest example of that on our roster, and probably the most divisive coffee we sell.

What was done to it

The cherry goes through carbonic maceration twice, sealed in a tank flooded with CO₂, where fermentation runs without oxygen and produces a different set of acids and esters than an open-air ferment would. Between those two stages it’s dosed with mossto: the concentrated juice pressed from coffee mucilage, in this case infused with Galaxy hops.

If you want to understand what natural processing does, drink this next to the Aricha washed lot. Same country, similar altitude, heirloom varieties in both. Almost everything separating them in the cup comes down to what happened in the first week after picking.

Raised beds, and why they matter

Natural process means the cherry dries whole, fruit still attached, and the seed takes on flavour from the pulp fermenting around it. Done badly this produces mould, over-ferment, and a cup that tastes like compost. Done well it produces the most intensely fruited coffee on earth.

Adorsi Washed Kurume

Mon, 01 Sep 2025 11:00:00 -0800

This is the coffee we hand people who say they don’t like light roasts. It is about as classical as Yirgacheffe gets, and it makes the argument for washed Ethiopian coffee better than any explanation would.

Kurume, and the grading

Kurume is one of the heirloom varietal groups found across the Yirgacheffe area: small, dense beans, typically cupping with more floral and citrus character than the larger-seeded types. Grade 1 is the top of the Ethiopian scale, meaning almost no defects in a 300-gram sample. That matters more than it sounds: a handful of defective beans is enough to drag a whole batch toward the muddy end.

Ubuto Washing Station

Mon, 01 Sep 2025 11:00:00 -0800

Burundi is landlocked, small, and sits in the shadow of Rwanda and Ethiopia in almost every conversation about East African coffee. The coffee itself deserves much better than that, and this lot is the case in point.

Double washing

Standard washed processing ferments the seed once to break down the mucilage, then rinses. Double washing, common in Burundi and Rwanda, runs a second, shorter soak in clean water after the first ferment, typically overnight.

Mbale Mountain Harvest

Mon, 01 Sep 2025 11:00:00 -0800

Uganda exports more coffee than almost anywhere in Africa, and the overwhelming majority of it is robusta headed for instant coffee and cheap blends. The arabica grown on the Mount Elgon slopes around Mbale is a completely different proposition and still trades at a discount largely because of the country’s reputation.

That’s a sourcing opportunity, and this is the lot that proves it.

Growing on a volcano

Mount Elgon is an extinct shield volcano on the Kenyan border, with deep volcanic soils and reliable rainfall. Farms sit high. High enough that the cherry ripens slowly, which concentrates sugars in the seed. The coffee is washed on raised beds by smallholder groups organised into an organic-certified cooperative structure.

Farmgate means the price was negotiated with the producer at her farm rather than set by an exporter working from the commodity market. For a smallholder in Cajamarca that difference is substantial, and it’s the main reason we buy Peruvian coffee this way even though it’s more work than the alternative.

Why Peru is underrated

Peruvian coffee has a reputation for being pleasant and unremarkable: the coffee you put in a blend to add body without adding a point of view. That reputation comes from decades of the country’s crop being sold as anonymous organic bulk.

Ecuador produces almost no coffee by regional standards. The country consumes most of what it grows and exports a rounding error compared to Colombia next door. What does leave tends to be very good, because the only producers bothering with the export paperwork are the ones with something worth exporting.

Sidra, and anaerobic washing

Sidra is the interesting half of this lot. It’s a relatively recent Ecuadorian variety, generally understood to descend from a Bourbon–Typica cross with Ethiopian landrace material somewhere in its history. It produces a cup much closer to a Gesha than its parentage suggests, at a fraction of a Gesha’s price.

Juan Peña

Mon, 01 Sep 2025 11:00:00 -0800

The counterpoint to the Pichincha lot: same country, no fermentation tricks at all. Juan Peña picks ripe, pulps promptly, ferments in open tanks, and dries on raised beds. It’s the process almost everyone used before anaerobic tanks became fashionable, executed carefully.

Saraguro

Saraguro sits in Loja province near the Peruvian border, an Indigenous Kichwa highland region better known for textiles than for coffee. Farms are small and high, and coffee is generally one crop among several rather than a monoculture.

Roasting

Sun, 19 Jul 2026 10:00:00 -0800

“Medium roast” is close to meaningless. It describes a colour, and colour is the thing about a roast that tells you least. Two batches can finish at identical surface colour and taste nothing alike, because what matters is the path the bean took to get there and how long it spent in each stage.

A roast curve carries that information. So we publish ours, along with the aggregate numbers from every batch we have logged.

A Darker Roast, On Purpose

Tue, 14 Jul 2026 16:00:00 -0800

Almost everything on our roster is roasted light to medium, because that’s what keeps origin character in the cup. So this is the exception, and it’s worth writing up because it shows what the roast alone can do.

A customer asked for something specific: low acidity, and an espresso that pulls creamy. Not a flaw to hide, just a preference. That request points in one direction, and it isn’t our usual one.

Roasting on Vashon Island

Wed, 10 Sep 2025 08:00:00 -0800

What running a roastery on an island near Seattle changes about the work, from ferry logistics to how long we spend on a profile.

Why We Only Roast Single-Origin Coffee

Every batch we roast is one lot. What that buys, what it costs, and why we’re not planning to blend.

About

Mon, 01 Sep 2025 11:00:00 -0800

Midnight Bloom is a small-batch coffee roastery on Vashon Island. Technically Maury Island, which is joined to Vashon by an isthmus narrow enough that nobody local bothers with the distinction.

It is small. There’s no café, no storefront, and no wholesale programme of any size. Coffee is roasted to order, packed, and taken on the ferry.

Why the site looks like this

Most roaster websites are shops with a blog bolted on. This one is closer to the reverse: a working notebook that happens to have a link to where you can buy the coffee.

Brewing

Mon, 01 Sep 2025 11:00:00 -0800

There are four variables that matter: ratio, grind, temperature, and time. Almost every brewing problem is one of them being wrong, and almost every brewing guide tells you to adjust all four at once.

Change one thing at a time. Write down what you changed. That’s the entire method.

Starting points by method

These are places to start, not rules. Once a coffee is dialled in, the numbers for that coffee matter more than the numbers here.

Understanding Geisha Coffee

Sat, 30 Aug 2025 14:00:00 -0800

Geisha is the variety people mean when they talk about a coffee that tastes like tea and costs like wine. Most of the reputation is deserved. Some of it is auction theatre. Here is what’s underneath it.

Where it comes from

The variety, spelled Geisha or Gesha depending on who is selling it, originated in the Gori Gesha forest in Ethiopia, where it grew wild before anyone was propagating it deliberately. It is genetically distinct from most other arabica varieties, and that distinctiveness is the reason it keeps its character across very different growing regions. A Gesha grown in Panama still tastes recognisably like Gesha.

What a Roasting Day Actually Looks Like

Thu, 28 Aug 2025 16:00:00 -0800

Roasting looks like a craft from the outside and mostly feels like process control from the inside.

Before anything is hot

The first decision is which lots to run and in what order. This isn’t arbitrary. The drum carries heat between batches, so you sequence from lighter profiles up to darker ones rather than trying to drag temperature back down mid-session.

Then the green gets checked. Moisture content should sit around 10–12%; anything higher and the drying phase needs extending or the batch will finish uneven. Density matters too, because dense high-grown coffee absorbs heat differently from softer lowland beans, and the same profile applied to both produces two different results.

Coffee After Dark, Without Wrecking Your Sleep

Fri, 15 Aug 2025 22:30:00 -0800

Given the name, we get asked about evening coffee fairly often. The answer is less about beans than about pharmacokinetics.

The half-life problem

Caffeine’s half-life in most adults is five to six hours, though the range across individuals is wide. Genetics, liver enzyme activity, hormonal contraceptives, and smoking all shift it, and the spread runs from about two hours to over nine.

Take the middle of that range. A strong cup at 9 pm still has roughly half its caffeine circulating at 3 am, and a quarter at 9 am the next morning. That’s why “I can fall asleep after coffee” and “coffee doesn’t affect my sleep” are different claims. Sleep onset is often fine; what degrades is slow-wave sleep, and you don’t perceive that directly. You just feel unaccountably flat the next day.
