Grinding fresh roasted coffee isn't set by a manual — it's set by how many hours have passed since first crack. If you grabbed a bag on Saturday at the Marché de l'Abattoir, exit from the Manufakture car park, Anderlecht, you're holding the freshest coffee in Brussels: roasted by Golden in the open air, a few hours ago. And Sunday morning, in the machine, it runs slow, it gurgles, it spits an overly foamy crema. It isn't faulty. It's breathing.
Why grinding fresh roasted coffee chokes your espresso
Fire leaves carbon dioxide inside the beans. For days, the coffee lets it go slowly — that's degassing. Supermarket coffee, weeks old, lost its gas long ago; that's why it runs obediently, without soul. Ours, roasted on the weekend, keeps that gas alive. The moment you grind, the bean's surface bursts open: one study shows ground coffee can lose up to 75% of its CO₂ in 90 seconds. That gas fights the water in the portafilter. That's why the espresso chokes — not because you failed, but because you bought coffee still warm from the market.
Grinding fresh roasted coffee: coarse at first, finer by the day
The rule is simple, and your hands can feel it. For the first 3-4 days after roasting, set the grinder coarser than instinct tells you — let the water pass between gas-swollen beans. As the coffee rests and degasses, tighten it gradually, a little finer each day. Around day 5-7 the lot enters its golden window: the gas has settled, the flavours have set, and the setting turns stable. Don't toss those first "failed" shots — they're your map. Every pour tells you where the coffee sits in its own rhythm.
Cezve and filter: same gas, different patience
In a cezve, fresh gas pushes the foam over the rim sooner — pull the pot off the flame faster in the early days. On filter, you'll see the bed "bloom" more violently; pour in two stages and give it 40 seconds to breathe. Same coffee, same week — just different patience.
The market and grinding coffee roasted on a Saturday
Here's the difference no webshop can give you: with us, the roast date isn't a label — it's the day you were there. The weekend sky wrote the lot's profile — a Saturday with a north wind roasts differently from a heavy, humid Sunday. The beans felt that weather, and they carry it into your cup. Adjusting your grinder for fresh roasted coffee isn't tweaking a technical parameter. It's listening to a lot that will never come back.
Buy the coffee as whole beans, grind at home, right before extraction. That's how you catch the aromas before they flee into the air. And we're at the market only on Saturday and Sunday — for as long as Golden's fire burns.
Come with your grind questions. We'll tell you which day each lot is on and how to grind it to catch it at its peak. Small lots go fast — those who know, know.
Brut. Sauvage. Imprévisible.
