How coffee actually gets from origin to your Sydney café

The espresso sitting in front of you has travelled further than you probably think.

Before it was ground, tamped, and extracted through 9 bars of pressure in a Surry Hills café, that coffee was a cherry on a tree — possibly in Ethiopia, Colombia, Guatemala, or Indonesia. Between the tree and your cup, it passed through a dozen pairs of hands, crossed at least one ocean, and was transformed multiple times.

Most of that journey is invisible. Here's what it actually looks like.

Step 1: Growing

Coffee grows within a band roughly 25 degrees either side of the equator — the coffee belt. The plant needs altitude, consistent rainfall, and the right temperature range. Most of the world's best specialty coffee comes from smallholder farms, often at elevations above 1,500 metres, where the cooler temperatures slow the cherry's development and allow more complex sugars to accumulate.

The variety of coffee plant matters too. Heirloom Ethiopian varieties taste completely different to Bourbon or Caturra varieties grown in Latin America. Gesha — originally from Ethiopia, now grown extensively in Panama — has become one of the most sought-after and expensive varieties in the specialty market.

Step 2: Harvesting

Most specialty coffee is hand-picked. That sounds romantic, but it's more specifically about precision — harvesters select only ripe cherries (typically bright red or yellow, depending on variety), leaving unripe ones on the branch. This selective picking, versus strip-harvesting entire branches at once, makes an enormous difference to cup quality.

A skilled picker might harvest 100kg of cherries in a day. It takes roughly 2,000 hand-picked cherries to produce 500g of roasted coffee.

Step 3: Processing

This is the step most people don't know about, and arguably the one with the biggest impact on flavour after origin itself.

Processing is how the seed (the coffee bean) is removed from the fruit. The three main methods are washed, natural, and honey. In a washed process, the cherry's outer fruit is stripped mechanically and the beans are fermented in water to remove the remaining mucilage — this produces clean, bright, origin-forward flavours. In a natural process, the whole cherry is dried on raised beds in the sun, with the bean fermenting inside the fruit — this produces heavier body, more fruit character, and often wine-like complexity. Honey process sits in between, with varying amounts of mucilage left on the bean during drying.

More recently, anaerobic fermentation — where beans ferment in sealed tanks — has produced some extraordinary and unusual flavour profiles, particularly from Colombian producers.

Step 4: Milling and grading

Once processed and dried to the right moisture content, the beans are milled to remove their parchment layer, sorted by size and density, and graded for defects. High-grade specialty lots are hand-sorted as well as machine-sorted.

This is also where Q-grading happens — certified tasters evaluate samples and assign scores. Only lots scoring 80+ qualify as specialty grade. Those lots are then separated and priced accordingly.

Step 5: Export and import

Green (unroasted) coffee is packed into jute or grain-pro bags and shipped via container. The journey from Ethiopia to Sydney takes several weeks. Temperature and humidity during transit can affect quality — specialty importers monitor this carefully, and some use climate-controlled containers for particularly delicate lots.

In Australia, importers manage customs clearance and warehouse the green coffee. Roasters source from importers, or increasingly, direct from farms or cooperatives through direct trade relationships. Direct trade typically means higher prices to the farmer, more transparency in the chain, and earlier access to exceptional lots.

Step 6: Roasting

Green coffee is dense, grassy-smelling, and essentially undrinkable. The roaster's job is to apply heat in a carefully controlled way to develop the hundreds of aromatic compounds that make coffee taste like coffee.

The roast profile — how fast the temperature rises, when the bean 'cracks' (a physical transformation), and how long it's held at various temperatures — determines the final character of the coffee. Roasters develop profiles over multiple batches, tasting constantly, adjusting until the coffee expresses what they want it to express.

Specialty roasters typically roast lighter than commercial operations. Lighter roasts preserve more of the origin's character; darker roasts develop roast flavours that can mask the raw material. At Black Market Coffee, every lot gets its own profile developed from scratch.

Step 7: The café

The café is the last translation point. A coffee that's been grown, processed, transported, and roasted beautifully can still be wrecked by stale beans, poor grinder calibration, wrong water temperature, or inconsistent technique. This is why specialty roasters like us don't just drop off beans and disappear — we work with wholesale partners on dialling in, equipment maintenance, and ongoing training.

The next time you taste something interesting in your espresso — a hint of apricot, a flicker of dark chocolate, something bright and acidic you can't quite name — that's the whole chain working. Every step got you there.
