With the French press method, Coffee is brewed by placing the coffee and water together, stirring it and leaving to brew for a few minutes, then depressing the plunger to trap the coffee grounds at the bottom of the beaker. Excessive (6 cups a day) consumption of unfiltered coffee has been associated with an increase in cholesterol. However, there does not appear to be an association of increased risk of coronary heart disease with coffee consumption.
Because the coffee grounds remain in direct contact with the brewing water and the grounds are filtered from the water via a mesh instead of a paper filter, coffee brewed with the French press captures more of the coffee's flavour and essential oils, which would become trapped in a traditional drip brew machine's paper filters. French pressed coffee is usually stronger and thicker and has more sediment than drip-brewed coffee. Because the used grounds remain in the drink after brewing, French pressed coffee left to stand can become bitter. "A typical half-liter French press is considered expired after 20 minutes."
