How Much Caffeine Is in a Cup of Coffee?
Share
If you’ve ever wondered how much caffeine is in a cup of coffee, you’re not alone. The caffeine content in your daily brew can vary depending on the type of coffee beans, brewing method, and serving size. Whether you enjoy a bold espresso, a smooth filter coffee, or a refreshing cold brew, understanding how caffeine affects your energy and focus can help you make the right choice for your daily cup of coffee.
Average Caffeine Content in a Cup of Coffee
A standard cup of brewed coffee (240ml / 8oz) typically contains between 70mg and 140mg of caffeine, though this can vary depending on how it’s prepared and the source of caffeine (Arabica or Robusta).
| Coffee Type | Serving Size | Average Caffeine (mg) |
|---|---|---|
| Brewed filter coffee | 240ml | 90–140mg |
| Espresso (single shot) | 30ml | 60–80mg |
| Americano | 240ml | 75–120mg |
| Instant coffee | 240ml | 30–90mg |
| Decaf coffee | 240ml | 2–5mg |

Factors That Affect Caffeine Levels
Several factors influence how much caffeine ends up in your cup — from ground coffee beans to hot water contact time. Here’s what to consider:
1. Coffee Bean Type
Not all coffee beans are created equal when it comes to caffeine:
-
Arabica beans generally contain less caffeine (around 0.8–1.4%).
-
Robusta beans usually contain 1.7–4% caffeine, making them ideal for those who like strong, full-bodied coffee drinks.
You can explore both varieties with our Arabica Blend Coffee or the robust India Cherry Coffee — both offering unique flavour profiles and varying amounts of caffeine.
2. Brewing Method
The brewing method determines how much caffeine is extracted from the ground coffee beans.
-
Espresso: Short extraction time but highly concentrated, giving a quick caffeine hit.
-
Filter coffee / pour-over: Uses hot water for longer contact, producing a balanced brew with moderate caffeine content.
-
Cold brew: Steeped slowly for hours, resulting in a smooth yet strong source of caffeine.
If you love cold brews, try our refreshing Savannah Ice Coffee for a smooth, highly caffeinated cup.
3. Roast Level
It’s a common myth that dark roasts contain more caffeine. In reality, lighter roasts retain slightly more caffeine, as dark roasting reduces bean density.

Caffeine in Different Coffee Drinks
The amount of caffeine in your cup can vary depending on how your favourite coffee drinks are prepared:
| Coffee Drink | Serving Size | Average Caffeine (mg) |
|---|---|---|
| Espresso (single shot) | 30ml | 60–80 |
| Americano | 240ml | 75–120 |
| Latte | 240ml | 60–120 |
| Cappuccino | 240ml | 70–110 |
| Filter Coffee | 240ml | 90–140 |
| Decaf Coffee | 240ml | 2–5 |
Looking for a gentler sip? Try our Swiss Water Decaf Blend Coffee or Colombian Sugar Cane Decaf Coffee — perfect for those who love coffee flavour without the additional caffeine.
Managing Your Daily Caffeine Intake
The NHS recommends that healthy adults limit caffeine intake to around 400mg per day — roughly the equivalent of 3–5 cups of brewed coffee, depending on strength.
If you love your cup of coffee but want to moderate the effect of caffeine, consider alternating between caffeinated and decaf coffee options. Pair a strong Forte Blend Coffee with a lighter Mexican Water Decaf Coffee for balance.
Summary: How Much Caffeine Is in a Cup of Coffee?
The caffeine content in your cup of coffee can vary depending on the type of coffee bean, brewing method, and roast level. On average, a standard cup contains 70–140mg of caffeine. Lighter roasts tend to have slightly more caffeine, while decaf coffee contains only trace amounts.
