Do you fall asleep in line at the cafe again after drinking coffee a few hours ago? Should you have an espresso, a flat white, or a brewed coffee? But the roast: light or dark?
If you're like me and you like your cup of coffee with an extra kick in the ass, you may be wondering: how much caffeine is in coffee? What type of coffee has the most caffeine?

Type of Bean
The best place to start our search is at the source. There are two main species of coffee plants that find their way to your cup: Arabica and Robusta.
In general, Arabica grains are considered to be of better quality than Robusta grains. Although Robusta plants are much easier to grow than Arabica, they have a strong bitter earthy taste. Arabica, on the other hand, is known for its sweet and fruity aromas.
Arabica may be the more popular of the two, however, Robusta is the clear winner in the caffeine competition. On average, Robusta beans have twice the caffeine content of Arabica beans.
Robusta is easy to find, as it is almost always the grain of choice for cheaper brands, ready for supermarkets. Although most artisan roasters use Arabica beans, you can find high-quality Robusta roasts with a little digging.
Type of Roast
There is a popular myth floating around that darker cakes have more caffeine than light-profile cakes. Unlike the Loch Ness monster myth, these roasts have no more caffeine than light roasts. Many coffee scientists say that lighter roasts have the highest amount of caffeine, but they are also wrong.
Beans for beans, both roasts have about the same amount of caffeine, although it is a little more complicated than that.
When the beans are fried, they lose some of their mass, so the dark fried beans, which have been cooked for a long time, weigh less than lightly fried beans. Therefore, a kilogram of the dark roast will have a little more beans than a kilogram of lighter roasted beans.
When preparing, if you measure your beans in volume, the light roast will produce a more caffeinated cup of coffee. However, if you measure by weight, then darker brewed coffee will have more caffeine. If you scratch your head right now, don't worry, this puzzle has confused me for a while.
Look at it this way: a cup of roasted coffee on a light profile will have more caffeine than a darker roasted cup, because the lighter the roasting, the heavier and denser the beans. Although the volume is the same, the light roast will have more mass.
If you measure 20 grams of each roast (dark and light), it will have more caffeine because it has more volume. Both weigh the same, but since the darker roasted beans are less dense, you'll have more of them.
Type Of Beverage
Decaffeinated coffee, espresso, drip - different coffee drinks contain different amounts of caffeine. It may seem like an 8 oz standard. The brewed coffee cup has less caffeine compared to espresso, but it actually doesn't.
The average 8 oz caffeine content. drip coffee is about 94.8 mg, while the caffeine content of an espresso drink is about 62.8 mg. There will be some ugly side effects of the unknown caffeine intake, so keep reading.
So, if we compare drinks with coffee, then drip coffee is the best choice; however, espresso has more caffeine by volume than brewed coffee. For every ounce, espresso has about 40-55 mg of caffeine. The caffeine content of dripping coffee is only 9-18 mg per ounce.
The caffeine content of a coffee drink also depends on the size of its portion. If you make your double espresso, you get either as much or more caffeine than you would with a regular cup of dripping coffee, however, you will need a little espresso to beat the dreaded 20 oz. Starbucks Venti.
Decaffeinated coffee still has small traces of caffeine, and instant coffee is subject to different levels of caffeine.
What Type Of Coffee Has The Most Caffeine?
So which coffee has the most caffeine? Well, that depends, there are a few options. These highly caffeinated grains have been designed to have large amounts of caffeine. Make sure you are aware of a safe amount of caffeine intake before consuming such coffee. The health benefits of coffee can be greatly increased.
A double shot of espresso will beat a standard-sized drip infusion any day of the week, but it can't beat any 10-drip infusion. Whether you want to ensure a high caffeine content, choose any of those made with Robusta coffee beans.
