1. Sediment in French Press Coffee: An In-Depth Look

Sediment refers to the gritty coffee particles that end up in the cup when brewing with a French press. 

The metal filter allows more sediment to pass through versus paper filters.

Research by the American Society for Brewing Chemists showed sediment levels were 75% higher in French press coffee compared to drip on average.

Why Sediment is a Drawback

  • Texture – Sediment can make the coffee feel gritty or sludgy rather than smooth.
  • Taste – While some argue sediment enhances flavor, it can also cause over-extraction bitterness if the grounds keep brewing.
  • Appearance – Sediment clouds the coffee and takes away from its visual appeal.
  • Health – Compounds in sediment may increase cholesterol, however small amounts in moderation are unlikely to pose risks.
