Coffee gets us out of bed in the morning. Pure and simple. The reason? Caffeine in Coffee. We can’t seem to get enough of the stuff, particularly when we’re feeling tired and groggy and need an extra boost. But what do we really know about it? How much Caffeine in Coffee is there? What even is it?

What are the effects of Caffeine? And should we limit our Caffeine consumption? These questions and many more will be answered in this article. Discover more with The Kent and Sussex Tea and Coffee Company. What is Caffeine?

What is Caffeine?

Caffeine, known scientifically as trimethylxanthine, is a naturally occurring chemical stimulant found in around 60 plants. This includes of course Caffeine in Tea leaves and, of course, Coffee beans. It is technically classified as a drug - though, thankfully, it is legal and, for the most, safe.

Nevertheless, overconsumption can, like most drugs, lead to side effects - so be wary of the amount of Caffeine you consume. The effects of Caffeine, especially Caffeine in Coffee, include stimulating the brain. It is also medically useful to stimulate the heart while likewise serving as a mild diuretic.

Most people, however, enjoy it in their morning brew to start the day off. Caffeine works by blocking adenosine, a neurotransmitter that relaxes the brain. In essence, by blocking adenosine, Caffeine has the opposite effect. It makes us feel more alert and less tired. Caffeine in a cup of Coffee

Caffeine in a Cup of Coffee

There is no one answer to the question “how much Caffeine in a cup of Coffee?”. Indeed, it depends on a multitude of factors. Amounts of Caffeine differ, for example, depending on the type of Coffee (Flat White, Espresso Shots etc.), type of Coffee beans (Arabica or Robusta beans), roast style (medium-light, dark etc.) and serving size.

Examining these factors individually and in depth, we’ll find that Caffeine content when it comes to different types of Coffee can vary significantly. Below is a table showing a few popular types of Coffee and how much Caffeine, on average, each one contains:

Caffeine Levels in a Cup of Coffee

Filter Coffee (8 oz cup) 95-200 mg
Espresso (Single Shot) 75 mg
Latte (8 oz cup) 65-175 mg
Cappuccino (8 oz cup) 75-180 mg
Flat White (8 oz cup) 75-150 mg


When it comes to beans, there are two types. Arabica beans, which come from the Coffea arabica plant, account for 75% of Coffee production. Robusta beans, which come from the Coffea canephora plant, account for 25%. Despite Arabica beans being, for the most, more popular, it is Robusta beans that contain the most Caffeine - 1.5% more to be specific.

What about Coffee roasts? Contrary to popular belief, Coffee roasts have less of an impact on Caffeine content than many might think. Some say that lighter roasts contain more Caffeine than darker roasts. This might be true on occasions, but its effect is minimal at best. Finally, we have serving size. This should hopefully speak for itself. The bigger the cup, the more Caffeine. It’s as simple as that. Instant Coffee

Caffeine in Instant Coffee

Instant Coffee is a type of Coffee made by either freeze-drying or spray-drying the beans. After a few other stages, this ultimately creates a powder that, after adding hot water, forms your morning cuppa with convenience in mind. It’s the brew of choice for those who wish not to waste too much time making their Coffee. But how much Caffeine in instant Coffee is there?

On average, Instant Coffee contains 93-95 milligrams of Caffeine per 8 oz cup. Indeed, it differs only minimally to that of filter Coffee. If you are like us, however, then your loyalties lie with the latter of the two choices.

Here at The Kent and Sussex Tea and Coffee Company, we stock only the best, which includes 80 types of Coffee. It’s also worth noting that we pack everything fresh to order, ensuring not only quality but also consistency. How Much Caffeine in Decaf?

How Much Caffeine in Decaf Coffee?

It’s a common misconception that Decaf Coffees are entirely Caffeine-free. All Coffee, be it a fully Caffeinated Coffee or, indeed, Decaffeinated Coffee, contains at least a small amount of this chemical compound. Despite the decaffeination process reducing the Caffeine in Coffee content significantly, there will always be some left over.

If you’re looking for as little Caffeine as possible, then it very much depends on the decaffeination method applied to the beans. The most widely used method uses Methylene chloride as a solvent to extract the Caffeine. Ultimately, it sees the removal of 96-97% of Caffeine in Coffee; however, we as a company steer clear from this method due to safety concerns.

An alternative is to use Ethyl Acetate, a natural chemical, as a solvent. This method, like using Methylene chloride, extracts 96-97% of the Caffeine content. But also like the Methylene chloride method, we don’t use Ethyl Acetate, either! The only two methods we use are the CO2 process and the Swiss Water process. The CO2 method, as its name suggests, uses Carbon Dioxide to extract the Caffeine.

It's the safest and most efficient way to decaffeinate Coffee beans. Not only does it preserve the flavour molecules, ensuring great taste with every cuppa, but also extracts 96-98% of the Caffeine. The Swiss Water process, on the other hand, quite literally uses hot water put through a carbon filter to extract both the Caffeine and flavour molecules.

The use of a carbon filter ensures that the smaller caffeine molecules are trapped while the larger flavour molecules can eventually be returned to the Coffee. This method extracts 94-96% of the Caffeine from our very own Decaffeinated Water Processed Coffee Beans. Where to Buy
