What coffee for French press?

For a French press, favour coffees with a full body and a medium to medium-dark roast: Brazil, Sumatra, Colombia, Central American honeys. Coarse grind like sea salt, ratio 60-65 g/L, 4-minute steep. The sweet spot is a sweet, chocolaty, low-acid profile; very floral or bright coffees underperform in a long immersion.

The French press — or plunger pot — is the simplest immersion method: coffee is fully soaked for 4 minutes, then a metal mesh filters out most of the grounds. Unlike a paper filter that catches oils and fines, the French press lets both through — hence its signature dense body, oily mouthfeel and the 'coffee soup' texture regulars cherish. That texture favours coffees with natural body and roundness: Brazil (Cerrado, Sul de Minas), wet-hulled Sumatra Mandheling, Colombian Nariño or Huila, Costa Rican honey, Guatemalan Huehuetenango. A floral washed Ethiopian Yirgacheffe, by contrast, can feel shy in a press, its citrus notes muted by the fatty texture.

The ideal roast is medium to medium-dark. Long immersion fully extracts sugars developed during roasting (caramelisation, advanced Maillard), giving press coffee its signature dark chocolate, hazelnut and molasses character. A light roast turns grassy and under-developed, because four minutes of coarse-grind immersion cannot extract a light bean fully. A dark roast, conversely, drifts into burnt territory at that time.

Grind is the most critical variable. It should be coarse — think sea salt or granulated sugar. Too fine, and the grounds slip past the mesh, leaving sludge at the bottom and pushing the brew into over-extraction and bitterness. Too coarse, and the cup turns weak and watery. A blade grinder is disqualified: it produces a chaotic particle distribution that makes extraction erratic. A burr grinder — manual or electric — from 150-200 € onward is plenty.

Recommended ratio is 60 to 65 g/L — 30 to 32 g for the standard 500 ml press. Steep 4 minutes, plunge slowly, then decant immediately into a carafe or cup. Leaving coffee in contact with the grounds after plunging continues extraction and turns the cup bitter within minutes.
