How much coffee is too much?

According to the Mayo Clinic and the USFDA, about 400 milligrams of caffeine a day. While the amount of caffeine in coffee ranges, that’s about four to five cups of brewed coffee or three to six espressos.

If you can only safely drink a few cups of coffee a day, you better make sure it’s something special. Something like Saint Frank Coffee, expertly sourced and carefully roasted in San Francisco.
