around 300 mg
but it depends how the coffee was brewed
3 cups of coffee is really too much for me to handle.
It all depends on the roast. The darker the roast, the less caffeine. It is that simple.
A french roast has less caffeine than a medium roast. Just look at the coffee can label. It will tell you what roast it is.
Managed a Starbucks owned Seattle's Best Cafe' for 3 years
Cup of coffee depending on size has 90-150 mg
Instant coffee depending on size has 60-80 mg
or instant would have 180mg-240mg
