Your Guide to How Much Caffeine Is in Coffee

It doesn’t matter if you slept like a baby or were up all night with one; most of us want to jump-start our mornings with a hot cup of coffee. Cradling a warm mug and smelling your freshly brewed pick-me-up is a morning ritual we look forward to. We crave that little (or large) jolt of energy and alertness.

But how much caffeine in coffee do you need to open your eyes in the morning? Turns out the type of coffee and its brewing method matters.

How Much Caffeine Is in Your Coffee?

From drip to French roast to cold brew, each brewing method has a different amount of extraction; this refers to how much caffeine is extracted from the coffee bean for your drink.

Coffee drinks that soak the beans like Turkish coffee are stronger than pour-over methods because the water has more time to absorb the coffee’s caffeine. Another factor that affects the caffeine content is the size of the grind. Finely ground coffee beans produce a more caffeinated coffee because they have a larger surface area overall and a higher extraction. Finally, the hotter the water used to brew, the more extraction and thus more caffeine your coffee will have.

Keurig Cup

75-150 mg caffeine per 8-ounce cup

Single-serve coffee makers like Keurig produce coffee that is slightly higher in caffeine than traditional coffee makers. That’s because those little pods can hold a large amount of coffee. Keurig machines can also produce hotter water than most coffee makers.

French Press

80-135 mg caffeine per 8-ounce cup

Hosting a bridal shower or friends’ brunch? Place a French press coffee maker on the table for delicious coffee and an elegant touch. Just don’t expect the guests to get too lively. French press coffee is low in caffeine because the grinds are so large. They have to be, otherwise, you’d be left with a cup full of coffee grounds.

Here’s everything you need to know about how to use a French press coffee maker.

Drip Coffee

165 mg caffeine per 8-ounce cup

A cup of regular drip coffee from a coffee maker hits the spot in the morning but won’t give you much caffeine compared with other methods. The water in coffee makers doesn’t get very hot, so less caffeine will be extracted. The coffee grinds for a traditional coffee maker are larger than other varieties, too. If a classic cup of coffee is all you need to wake up, be sure to invest in one of the best coffee makers.

If you’re feeling fancy, treat yourself to a pour-over coffee at home or from your local craft coffee shop. The coffee grinds in pour-over coffee are larger; otherwise, the water would pool in the grounds and never make its way down to your mug. Pour-over can give you more caffeine than drip because of the water temperature; it requires extra hot water to brew.

Cold Brew

155 mg caffeine per 8-ounce cup

The amount of caffeine in a glass of cold brew coffee will vary depending on how concentrated your brew is. Cold brew coffee uses coffee grounds soaked in water, which usually yields a high-caffeine drink. However, because they’re brewed in cold water, the extraction is much lower than in hot. Cold brew is usually diluted with water or milk, so the more dilute, the less caffeine per sip.
