What you are actually paying for

Every so often someone lines up two bags of coffee — one from a supermarket, one from a roaster whose name is written small on the label — and asks, reasonably, whether the second one is a con.

It is a fair question. The answer is not a defence of high prices. It is arithmetic, and most of it happens long before anyone roasts anything.

Start with the floor, not the ceiling

Commodity coffee is priced against a global benchmark that moves with weather, currency and speculation, and has spent much of the last two decades below what it costs a smallholder to grow it. When a supermarket bag is cheap, that price has to come from somewhere. It usually comes from the farm.

So the suspicious number in the comparison is not the expensive bag. It is the cheap one.

Why good coffee is expensive to grow

Cheap coffee is grown where coffee is easy to grow: flat, warm, open land, planted with one thing, harvested in one pass — increasingly by machine, which strips a branch of everything on it.

That is the problem. Coffee cherries on a single branch do not ripen together. A machine pass takes the ripe, the green and the overripe in the same bucket, and the cup afterwards tastes like an average of all three.

Coffee that tastes like something is usually grown the other way round:

• At altitude. Cooler nights slow ripening. Slower ripening concentrates sugars and acids. It also means fewer harvests and lower yields.
• Under shade, among other plants. A monoculture grows volume. A mixed system grows soil, shade, insects and fungi — and, incidentally, better fruit. The plant is doing more work under mild stress, and the fruit is better for it.
• By hand, selectively. Pickers walk the same tree several times across a season, taking only what is ripe. On a slope. In humidity. It is hard physical work, and it is the single largest cost in a bag of good coffee.

Then there is variety. Some plants simply give less. A low-yielding cultivar that is fussy about disease and climate will always cost more per kilo than a robust workhorse, for the same reason a low-yield vineyard costs more than a high-yield one. Nobody is being greedy; there is just less of it.

Processing, and where the money starts to get strange

After picking, the fruit has to be turned into a dry green seed. The classical methods — washed, natural, honey — are ways of harnessing what the cherry already contains.

Newer methods go further: controlled fermentations, temperature-managed tanks, added time, added measurement. These cost money twice. Once directly — tanks, thermometers, labour, spoiled lots — and once indirectly, in the years of trial and failure it took to arrive at a repeatable result. Someone paid for those failures.

It is worth being honest about what this buys. Careful processing can reveal a coffee. Aggressive processing can overwrite it, until the flavour in the cup belongs more to the fermentation than to the farm. Both are sold at high prices. Only one is really about origin, and knowing which you prefer is a legitimate taste, not a moral position.

There is a wine parallel here that holds up reasonably well: mass blends at one end, single vineyards at the other, and somewhere off to the side a whole category of interventionist winemaking that people either love or find exhausting. Coffee now has all three.

Rarity does the rest

Even with no unusual processing at all, some lots are small, excellent and wanted by everyone. A few dozen bags, a competition score, and buyers bidding against each other — the price is not a story about ethics or marketing, it is supply and demand behaving exactly as you would expect.

Perspective helps. A celebrated bottle of wine can cost several hundred euros and give you five glasses. The most sought-after coffee in the world, bought as beans, gives you dozens of cups for a fraction of that. Whatever else specialty coffee is, it remains an unusually cheap way to taste the top of a category.

Fair trade and specialty trade are not the same thing

These get conflated constantly, so it is worth separating them.

Fair trade certification sets a minimum price and a small premium above the commodity benchmark, and adds standards on labour and organisation. It was designed as a floor under a broken market, and as a floor it does real work: it protects growers when prices collapse. But it is a floor, not a ladder. The minimum is calculated against commodity coffee, not against what it costs to grow something exceptional, and in many origins it still does not reach a living income. Certification also costs money to obtain and maintain, which excludes many of the smallest producers — including plenty who farm well.

Critically, fair trade pays for compliance, not for quality. A certified lot and an outstanding certified lot fetch the same certified minimum.

Specialty trade works from the other end. Price is negotiated per lot, against cup quality, and typically lands well above both the commodity price and the fair trade minimum — often several multiples of it. That difference is the incentive: a farmer who invests in selective picking, in drying beds, in slower fermentation, gets paid more for the result rather than for holding a certificate.

Neither model is automatically honest. Specialty pricing can be opaque; a high shelf price does not prove a high farm gate price. The questions worth asking a roaster are simple ones, and good roasters answer them without flinching: who grew it, what was paid for it, and how many times have you bought from them.

What this means for the bag on your shelf

None of this obliges anyone to drink expensive coffee. An honest, well-roasted daily coffee at a sane price is a good thing, and drinking one is not a failure of taste.

But when the price gap appears, it is worth reading in the right direction. The expensive bag is expensive because someone climbed a hill several times to pick it ripe, and was paid enough to do it again next year. The cheap bag is cheap because most of those costs were pushed somewhere out of sight.

That is the whole of it. Pay attention to which one you are holding.
