Average Caffeine Content in a Cup of Coffee

A standard cup of brewed coffee (240 ml / 8 oz) typically contains 70–140 mg of caffeine, although this can vary based on the type of coffee bean, how it's brewed, and even how finely it's ground.

Here’s a breakdown of common coffee types and their average caffeine content:

Factors That Affect Caffeine Levels

Several factors affect caffeine content in your cup:

1. Type of Coffee Beans

• Arabica beans generally contain less caffeine than Robusta — if you’re after a more moderate kick, Arabica is a great choice.

• Robusta beans pack more caffeine, so for a strong, powerful brew consider a robust bean.

2. Brewing Method

How you brew your coffee directly affects how much caffeine is extracted from the ground coffee beans:

• Espresso: Short extraction time, but very concentrated — great for a fast boost.

• Filter / Pour-over: Longer contact with water temperature at the right point, delivering moderate caffeine.

• Cold Brew: Steeped for hours, often yielding a smooth but potent caffeine-rich result.

3. Roast Level

Counterintuitively, light roast coffees typically retain slightly more caffeine than darker roasts, because darker roasting reduces bean density. For a roast that balances flavor and caffeine, try our Blonde Roast Coffee Beans. If you want something richer and more intense, go for French Roast Coffee.

• Espresso (single shot, 30 ml): ~60–80 mg

• Americano (8 oz): ~75–120 mg

• Latte (8 oz): ~60–120 mg

• Cappuccino (8 oz): ~70–110 mg

• Filter Coffee (8 oz): ~90–140 mg

Managing Your Daily Caffeine Intake

Health experts often recommend that healthy adults limit caffeine intake to about 400 mg per day, although this depends on how strong your coffee is and how large your servings are.

If you want to moderate your caffeine intake while still enjoying great coffee, try rotating between a high-caffeine roast and a decaf. For example, pair our French Roast Coffee for your morning brew with Decaf Peru Coffee for a gentler second cup.
