Understanding French Press Coffee

Across the long history of coffee, people have developed many brewing tools to make delicious coffee more conveniently - and the French press is one of them. Also known as a press pot, it consists of a heat-resistant glass carafe and a metal filter screen. The French press is one of the simplest brewers around, but sludge and sediment problems crop up constantly in use. Here are our tips for dealing with them.

When brewing with a French press, there will always be some coffee grounds - and even if no granular particles remain, fine powder residue will still make the coffee cloudy. Look carefully at the bottom of the cup after drinking and you will see sediment like fine mud. The causes are coffee ground too fine, or pressing the plunger down too quickly, which stirs grounds back into the liquid.

Three Methods to Remove Coffee Grounds

To combat the grounds a French press produces, try three things:

First, choose a coarser grind. If you grind your own coffee, simply adjust the setting coarser. Larger particles will be caught by the filter screen instead of slipping into the coffee below.

Second, control your pressing speed. Press slowly and steadily - pressing too quickly flushes grounds back up into the coffee liquid.

Third, invest in a quality grinder. Every grinder produces some fines, but a good one minimizes them dramatically.

French Press Coffee Making Steps

Step 1: Remove the filter rod from the French press.

Step 2: Add 20 grams of freshly roasted, ground coffee.

Step 3: Slowly pour hot water over the grounds.

Step 4: Do not fill it too full - stop about half a centimeter below the handle, making sure all the grounds are submerged.

Step 5: Let it sit and start timing for about 40 seconds.

Step 6 (when time is up): Use a spoon to stir quickly in a circle.

Step 7: After stirring, a fine brown foam will appear on the surface.

Step 8: Gently cover with the lid (do not press the rod down yet) and let it sit for another minute.

Step 9: When time is up, hold the lid with one hand and slowly, steadily press the rod down with the other.

Step 10: Pour out the coffee immediately, and a fragrant cup is ready.

French Press Coffee Bean Brand Recommendations

FrontStreet Coffee's roasted single-origin beans work beautifully in a French press, with full guarantees in both brand and quality and suitability across many brew methods. Better still, the value is outstanding: a half-pound 227-gram package costs only about 80-90 yuan. At 300ml per cup with a coffee-to-water ratio of 1:15, one package makes 11 cups - about 8-9 yuan per cup, extremely cost-effective compared to coffee shops that often charge tens of yuan per cup.

FrontStreet Coffee is a roastery with a small shop but a diverse range of bean varieties, where you can find both famous and lesser-known origins, along with online ordering services.

FrontStreet Coffee Recommendation

Because the French press is a full-immersion brewer, grind choice matters enormously: FrontStreet Coffee recommends a coarse-sugar grind (about setting 10.5 on an EK43s electric grinder, or 26 clicks on a hand grinder - closer to small gravel than fine sand), a 1:15 ratio (15g of coffee to 225g of water), water around 90°C, and a 4-minute steep. Too fine a grind lets fines slip through the metal mesh and fill your cup with sediment; if you do grind finer for more layered flavors, shorten the steep to avoid over-extraction.

For a low-acid, crema-rich black coffee, FrontStreet Coffee's PWN Golden Mandheling is the top pick - one of Asia's most famous specialty coffees, sorted three times by hand plus once by machine, medium-dark roasted to show rich spice, caramel, cedar, and dark chocolate aromas with a mellow body and good oiliness. If you prefer fragrance over body, the Strawberry Sugar Geisha blend - Costa Rican honey-process coffee blended with Panamanian washed Geisha - releases rose, citrus, grape, and dried blueberry aromas in the press, and turns to strawberry-soft-candy notes with milk.
