The amount of caffeine in a cup of coffee can vary quite a bit depending on several factors, but here are some general guidelines:
Standard 8 oz Cup of Brewed Coffee:
- Around 95 mg of caffeine on average
- Can range from 65-120 mg
Single Espresso Shot (1 oz):
- Around 63 mg of caffeine
Double Espresso Shot (2 oz):
- Around 125 mg of caffeine
8 oz Cup of Drip Coffee:
- Around 115-175 mg of caffeine
12 oz Cup of Brewed Coffee:
- Around 140-260 mg of caffeine
16 oz Grande Coffee from Starbucks:
- Around 310-350 mg of caffeine
The main factors that affect the caffeine content include:
Coffee Roast – Lighter roasts tend to be higher in caffeine than darker roasts.
Brew Method – Drip/filtered coffee has more caffeine than French press coffee.
Serving Size – The larger the serving, the more caffeine it contains.
Coffee Origin – Arabica beans tend to have slightly less caffeine than Robusta beans.
It’s also worth noting that caffeine amounts can vary quite a bit even among the same coffee drinks from the same café due to factors like batch, grind size, brew time, etc.
As a general rule of thumb, an 8oz cup of typical brewed coffee contains around 95mg of caffeine. But premium coffees like Death Wish can have as much as 700mg+ per 12oz cup.
