What Coffee Has the Most Caffeine?

This question is interesting. Most of us like to take coffee but don’t know how much caffeine they exactly contain. Have you ever thought of this?

When I started to think of it, I was baffled.

As you know, a lot of caffeine is bad for our health. But how much caffeine our body can tolerate? What type of coffee we should take?

Here I’ll answer all of these questions.

How much caffeine we can take per day?

If you are caffeine addicted then you should have knowledge of how much caffeine your body can tolerate per day.

Most persons can consume up to 400 milligrams (mg) of caffeine without experiencing negative effects. Equal to about four cups of coffee, ten cans of cola, or two “energy shot” drinks.

The FDA has warned that consuming caffeine in powder or liquid form can lead to overexposure. A single teaspoon of caffeine powder is equal to around twenty-eight cups of coffee. Caffeine in such large quantities is dangerous, perhaps fatal.

If you are pregnant or in the breastfeeding phase then you should take less than 200 mg of caffeine per day. Otherwise, it’ll have a bad impact on your newborn.

Which coffee contains how much caffeine?

The majority of cups of coffee that are 8 ounces (oz) contain between 80 and 100 milligrams (mg) of caffeine.

Caffeine content varies widely, however, depending on variables such as coffee variety, brewing technique, and manufacturer.

Based on the brewing process

We brew coffee in so many processes. But be aware, that those brewing methods can also vary in the amount of caffeine in coffee.

So let’s get to know…

Whether or not we are overdoing our daily caffeine dose depends a lot on how we brew the coffee:

Drip Coffee:

A cup of brewed coffee (24) contains approximately 70-140 mg of caffeine

Cold brew:

The caffeine content of a 12-ounce cup of cold brew coffee ranged from 153-238 milligrams in research conducted in 2017.


Approximately 63 milligrams of caffeine can be found in a single espresso shot that is 1 ounce in size.

Instant Coffee:

Caffeine levels in instant coffee are typically lower than those in brewed coffee.

Most ordinary instant coffee, enough for an 8-ounce cup, has roughly 62 milligrams of caffeine.

Decaffeinated coffee:

Though its name is decaffeinated, this one also contains some caffeine. To give you an idea, there are around 2 milligrams of caffeine in a standard 8-ounce cup of brewed decaf coffee.
