Five methods, treated as small engineering problems. The slider scales the recipe; the prose scales nothing. Choose your method by mood and your ratio by mass — never by volume, which is a measurement masquerading as a guess.
A meditative practice popular with people who have not yet learned that meditation is mostly waiting.
The V60 is a useful exercise in noticing how many ways water can find to misbehave. Bloom for forty-five seconds, then pour in two stages with a short rest between — most of the variance in your cup lives in the first thirty seconds, which is its own small lesson.
Aim for a flat bed at the end. A high-walled bed means channeling; a deeply scooped bed means you stirred when you should have poured.
If the drawdown finishes before three minutes, the grind is too coarse. If it finishes after four, the grind is too fine, or the paper is plotting against you. Both are correctable and neither is a referendum on your character.
The most forgiving method on this page, and accordingly the most slandered. Coarse grind, hot water, four minutes, plunge — the technique is mostly in the patience.
The French press is what the rest of these methods would look like with all the contrivance subtracted. Coarse grind, water just off the boil, four minutes, a slow plunge. The mesh filter lets oils and fines through, which is why the body is fuller than paper-filtered methods and why some people slander the cup as muddy. Both descriptions are accurate; they are descriptions of the same thing.
Plunge slowly — twenty to thirty seconds. A forced plunge agitates the bed and pushes fines into the cup that the mesh would otherwise have caught on the way down.
Decant immediately. Coffee left sitting on the grounds continues to extract, and the second cup from the press is always meaningfully worse than the first — a small lesson in why batch sizing matters.
The brewing method that trades temperature for time. Most of the work is done by the calendar, which is the most reliable collaborator in the kitchen.
The trade is straightforward — temperature for time. Cold water extracts most of the same flavors hot water does, just selectively, and leaves behind a large fraction of the bitter compounds that hot extraction can't help producing. Coarse grind, otherwise filtration becomes a separate engineering problem.
Stir once at the start to wet all the grounds. Then walk away. Sixteen hours is the canonical figure; anywhere between twelve and eighteen produces something good.
The recipe is forgiving in a way the others on this page are not. The only wrong move is impatience, and even that produces something drinkable — just thinner. Filter through a fine mesh, then again through paper if you object to silt. Refrigerated, it keeps for about a week, though it rarely gets that long.
What happens when an aerospace engineer concludes that coffee, like everything else, is fundamentally a fluid-dynamics problem.
Inverted, because gravity should not be allowed to start the extraction before you do. Add coffee, add water, stir at thirty seconds, cap with a rinsed paper filter, then leave it alone for ninety more.
The flip is the only step that benefits from confidence. Hesitation here is how you discover that your countertop is not, in fact, level.
Plunge slowly — thirty seconds, give or take — and stop the moment you hear the hiss. Anything beyond that is bitter air, charged at the same gram price as the coffee.
The only brewing method where the equipment routinely costs more than the relationship that introduced you to it.
Eighteen in, thirty-six out, in roughly half a minute. Three numbers, and the rest is mechanical sympathy. Distribution and tamp do most of the work the recipe pretends to do — uneven puck, uneven extraction, no amount of ratio worship will save you.
First drops at eight seconds is the canonical sign of a well-prepared puck. Earlier is a channel; later is a brick.
If the shot tastes sour, grind finer. If it tastes bitter, grind coarser. If it tastes like neither and yet still wrong, the beans are old, which is also correctable, mostly by buying fresher beans.
