Myth : There Is A Breed Of Decaffeinated Coffee Plants
Nope. Genetically speaking, caffeine is in all 100+ species of coffea, though the levels of caffeine vary somewhat. For instance, theres about twice as much caffeine in Coffea Robusta as there is in Coffea Arabica. However, the reason Peets exclusively selects Arabica coffee due to its superior flavor, not lower caffeine content.
The Caffeine Content In A Cup Of Coffee
So, how much caffeine is there in a cup of Joe?
Answer it depends on the type of coffee youre drinking. To give you an idea:6
- Brewed coffee contains 95 to 200mg of caffeine
- Espresso coffee contains 47 to 75mg of caffeine
- Instant coffee contains 27 to 173mg of caffeine
- Latte coffee contains 63 to 175mg of caffeine
What Is Decaffeinated Coffee
coffee, otherwise known as decaffeinated, is not just regular coffee, but cold coffee.
But dont let this name fool you. This decaffeinated coffee is not completely decaffeinated but contains much less caffeine than regular coffee. The lower amount of caffeine can be a bit confusing.
Because the Food and Drug Administration doesnt have strict regulations on decaffeinated coffee, its hard to know exactly how much caffeine youre getting in each cup. Additionally, the quality of its processing can affect caffeine levels, which is why one brand of coffee may cause you to quit caffeine, while another brand may cause you to peak quickly.
What we do know is that decaffeination usually removes about 97% of the caffeine, and on average decaffeinated coffee contains 3 mg of caffeine per cup compared to regular coffee which contains 85 mg in a cup which is a lot if you are sensitive to caffeine.

The Coffee With The Least Caffeine
Most associate espresso with a high level of caffeine due to how intense and bitter it is, so it may come as a surprise to you that espresso is the least caffeinated of all the different types of coffee beverages.
However, the only reason that espresso contains the least amount of caffeine is because of its small size. A typical single espresso is only around 25ml .
Unless you live in Italy, youre probably more used to a large mug of filter coffee. Because of the amount of ground coffee used to make an entire mug, filter coffee contains a much higher caffeine content.
For a typical 250ml cup of filter coffee, you need around 15g of ground coffee. For a single espresso, that figure is just 8g . Less coffee, less caffeine.
Its a little unfair to compare a 25ml beverage with one thats ten times its size. The correct approach is to compare the two beverages in terms of their caffeine concentration by volume.
| Beverage | |
|---|---|
| 0.4mg | 12mg |
Looking at the table, we can see that espresso has a caffeine concentration thats 4.5 times higher than filter coffee.
In order to achieve the same caffeine content as a 250ml cup of filter coffee, you would only need a 55ml serving of espresso.
And if you were to drink 250ml of espresso, youd consume a whopping 450mg of caffeine, which is more than the daily recommended intake.
So what can we conclude?
From a beverage serving perspective, because espresso is served in small volumes, it contains less caffeine than filter coffee.
Why Use Decaffeinated Coffee
Caffeine stimulates the central nervous system, increases the heart rate, constricts the blood vessels, and increases blood pressure. Those who can tolerate caffeine become more alert, more attentive, and more focused.
However, if you have too much caffeine or if you are intolerant to caffeine, the effect can turn negative: tremors, sweating as well as racing heart and stomach problems can result. Everyone with high blood pressure, heart problems, and sensitive stomachs can therefore be advised to use decaffeinated coffee!

These Chemicals Can Cause Major Health Issues
Methylene chloride is not a mild chemical. Dr. Rashimi Byakodi points to the way inhalation exposure irritates the nose, throat, and affects the nervous system.
“It’s believed to temporarily slow down our central nervous system,” says Dr. Ava Williams.
Perhaps most frighteningly, Dr. Byakodi says, “Methylene chloride is a possible mutagen and is reasonably anticipated to be a human carcinogen.”
Chemicals aside, even just the process of decaffeination can be problematic. “Some studies have shown a potential risk for triggering rheumatoid arthritis,” says Dr. Olivia Audrey.
Dr. Williams adds that the process has been found to increase fatty acids that can affect metabolic syndrome and increase the risk of heart disease.
These chemicals can affect your nervous system, cause rheumatoid arthritis, and even present a cancer risk.

How Much Caffeine Is In Coffee Vs Decaf
The average 8oz cup of coffee contains 95mg of caffeine, although the amount of caffeine can range from a minimum of 70mg to a high of 165mg.
As for decaf, the average 8oz cup contains 7mg of caffeine, with a range of 3mg to 15.8 mg.
Why is there such a range when it comes to the amount of caffeine in your coffee? It mainly depends on two factors: the roast and brew method.
Lets start with how the roasting process affects caffeine levels. All roasted coffee beans contain the same amount of caffeine, but when a bean is roasted, its density changes. The longer a bean roasts, the darker its color gets, the lighter its weight becomes, and the larger its size gets.
This means that the caffeine difference in a cup of coffee comes down to whether youre measuring your beans by volume or weight.
If measuring by volume using a coffee bean scoop, the light roast beans are smaller and denser, resulting in more beans per scoop. Conversely, a scoop of the dark roast beans, which are larger, will result in fewer beans per scoop. Because caffeine levels remain the same despite roasting time, the scoop with more beans will have more caffeine.
On the other hand, if youre measuring coffee beans by weight using a scale, the dark roast beans will provide the more caffeinated brew. As we discussed, the dark roast beans weigh less, therefore it takes more dark roast beans than light roast to reach the desired weight.

Does Decaf Coffee Taste Different
When you remove caffeine from coffee, you also remove some of the bitterness.
“It does taste slightly different,” Mr Demelis explains.
“It’s a smoother drink and easier on the palate but you’re not going to get the kick that you normally get from a coffee with caffeine.”
There are plenty of variables that affect a cup’s taste just like regular coffee.
Another factor is the process used. Coffee decaffeinated with chemical solvents will often have a distinctive flavour that Mr Wolff describes as “medicinal” or “tinny”.
“On the flip side, when we move to the non-solvent styles, we tend to get the coffees that show origin characteristics,” he says.

The Difference Between Decaf And Regular Coffee Explained
Coffee is one of the most popular beverages in the world. And many people enjoy drinking coffee due to its flavors and caffeine content.
But some people work around the clock to limit caffeine intake for health and personal preference reasons. It is the reason behind the rapid switch from regular coffee to decaffeinated counterpart.
So, what is the main difference between decaf and regular coffee? Decaf coffee has about 7mg of caffeine in a single cup, and regular coffee has at least 70mg of caffeine in a single cup.
This article provides further differences between decaf and regular coffee in a tabular form. Letâs find that out together below:
Is Decaf Coffee Bad For You
After all the warnings about coffee, it can be easy to assume that decaffeinated coffee is a healthy drink you can drink all day. But its not always that simple. Decaffeinated coffee is usually made from the same stuff as regular coffee. Most of the times, thats beans.
The coffee beans are processed in a little bit different way than regular beans, but theyre still beans that were once part of a plant. Yes it is bad for you, but not as bad as you think. After all, decaf coffee is not quite the same as the regular stuff.
The good news is, if you drink decaf all the time, your body will eventually get used to it and will adjust to its lower caffeine content. The bad news is, if you stop drinking decaf, your heart may not be able to adjust and the coffee will slowly poison your body
However, the use of methylene chloride in the decaffeination process has raised some concern among members of the coffee community as well as some consumers.

Why Does Decaf Coffee Still Have Caffeine In It
This has to do with how caffeine is removed from green coffee beans. Even though there is a thorough process used to extract as much caffeine from coffee beans as possible, it is difficult to get every milligram of caffeine out of every coffee bean. Therefore, decaf coffee still has trace amounts of caffeine present. You should know the exact number based on the nutrition facts of the coffee brand.
There’s Caffeine In My Decaf
In the study, published in the Journal of Analytical Toxicology, researchers set out to find out how much caffeine is likely to be found in popular decaffeinated coffees.
Researchers purchased 10 16-ounce decaffeinated cups of drip coffee from coffee shops and restaurants and analyzed them for caffeine content.
They found all but one — decaffeinated Folgers Instant, purchased at a Krystal fast-food restaurant — contained caffeine. The caffeine content ranged from 8.6 milligrams to 13.9 milligrams.
That’s about a tenth of the caffeine found in an 8-ounce cup of regular drip-brewed coffee, which contains about 85 milligrams of caffeine.
Next, researchers tested several samples of decaffeinated espresso shots and decaf brewed coffee from the same Starbucks location to determine if caffeine content varied in the same drinks from the same location.
The results showed that the caffeine content of the decaffeinated espresso shots varied widely — from 3 to nearly 16 milligrams the caffeine content of the decaf brewed coffee ranged from 12 to 13.4 milligrams per 16-ounce serving.
Researchers say even though the caffeine content of decaffeinated coffees is low, people could develop a dependence on them.

Recent Developed Decaffeination Process
After the Roselius process had stopped, coffee beans have been decaffeinated in the newly developed process which is safer for your health.
- Solvent-based processes: include the indirect solvent process and direct solvent process
- Non-solvent-based processes: include the Swiss water process and carbon dioxide process.
From here you might as well wonder what the differences are among the 4 types of decaffeinating processes. The truth is their differences rest in the solvent agent.
How Big A Deal A Little Caffeine Actually Is
The thing is, a few milligrams of caffeine is probably not enough to affect the majority of people, neurologist and sleep medicine specialist Ajay Sampat, M.D., assistant clinical professor at UC Davis Health, tells SELF. When its such a small amount, most people are probably not going to experience noticeable effects. Of course, this depends on a few factors, Dr. Sampat explains, like caffeine sensitivity and caffeine tolerance . Those of us who are mildly or moderately sensitive to caffeine and/or consume caffeine regularly are unlikely to be affected by the small amount of caffeine in decaf. And this is most of us.
But that doesnt mean the caffeine in decaf is a nonissue to everybody. For the minority of people who are really caffeine sensitive, even that small amount can be a lot, Dr. Sampat says. Some people are naturally highly sensitive to caffeine. So if youve ever noticed negative side effects of caffeinea quickening heart rate or feeling jittery, anxious, nauseous, or restless, per the U.S. National Library of Medicineafter a cup of decaf , you may well be caffeine-sensitive. Thats why the FDA advises that if you react strongly to caffeine in a negative way, you may want to avoid beverages altogether.

Is There Any Coffee That Is 100% Decaf
No decaf coffee process can claim 100% of caffeine removal, but Swiss Water certified decaf beans are 99.9% caffeine free, which is pretty darn close. Decaffeinated instant coffee will have come from beans that have gone through one of these same processes so it may still have a little caffeine in it.
Lets not forget that caffeine is not only found in coffee, but also other foods and drinks, so if youre trying to avoid caffeine at all costs, you need to take a look at your entire diet.

The Truth About How Much Caffeine Is In Your Decaf Coffee
Drinking coffee comes with a range of health perks, from liver protection to reduced risks of diabetes and heart disease. And if youd rather score its benefits without the jittery shakes, is the best way to go.
You may have heard theres actually some caffeine in decaf coffee, and its true. But it would take quite a few cups to make you feel like youve had the real thing.
The usually removes 94 to 98 percent of caffeine from a coffee bean, according to Mental Floss. While the U.S. Food and Drug Administration doesnt have any regulations around what can be called decaf, the baseline is typically a coffee thats had about 97 percent of its caffeine removed, spokeswoman Deborah Kotz told HuffPost.
The average 16-ounce, caffeinated coffee has 188 milligrams of caffeine, while the average 16-ounce decaf has 9.4 milligrams, according to a 2006 study from the University of Florida. Researchers say youd need to drink five to 10 cups of decaf in order to feel its effects.
Caffeine content in decaf coffee varies based on the type of beans used and the way theyre decaffeinated. Decaf coffee beans are usually made via one of three methods, which use either water, chemicals or carbon dioxide to draw caffeine out of the beans.
The University of Florida study found cups of decaf can range widely in caffeine content, and its rare to find a coffee thats completely decaffeinated.

The Swiss Water Decaffeination Process
Its a chemical free process for decaffeinating coffee, and uses two natural concepts to remove the caffeine: solubility and osmosis.
Coffee beans are soaked in a very hot Green Coffee Extract solution, or GCE for short, which dissolves the caffeine in the beans and migrates it into the GCE. The caffeine-rich GCE is then filtered through carbon filters which removes the caffeine but not the flavour. The beans are then re-soaked in the caffeine-free GCE to replace the flavour back into the beans.
How much caffeine is there in Swiss Water decaf coffee? The result is not only coffee that tastes very close to regular coffee, but its also 99.9% caffeine free. The Swiss Water Process is our first method of choice for decaffeinating coffee.
The Difficulty In Maintaining The Quality Of Decaf Coffee
Moreover, decaf coffee beans are really difficult to roast, unlike normal beans, they are less likely to respond consistently in the roasting machine meaning that it is hard to control their roasting process.
The normal coffee beans have a green color, and they will turn darker and is easy to control the process, yet the decaf coffee beans are already brown after the decaffeinating process. Therefore, the roasting process may pass a bit longer since they have less moisture content, and are prone to burn.
The decaffeinating process itself is also difficult because it is hard to maintain their original concentration of sensory character and flavor during the separating process. Understanding this will be a helpful assistant for you to choose your decaf coffee more carefully because the different type of roasting method has a different impact on the coffee flavor as well.
Whats more, the decaffeinating process has taken out and damaged a lot of flavor compounds or sensory characters that make coffee taste, so it is important to choose roasted coffee carefully, or you can look for a particular type of decaffeinating process. This way you can easily pick a suitable decaf coffee for your own preferences.

How Decaffeination Works
There are three key methods for removing caffeine from regular coffee beans: The most common uses a chemical solvent, another uses liquid carbon dioxide , and the last simply uses water.
All take green, unroasted coffee beans, soak or steam them until the caffeine is dissolved or their pores are opened, and then extract the caffeine.
While the CO2 and water methods are considered chemical-free, the solvent method relies on synthetic chemicals such as ethyl acetate and methylene chloride .
The Swiss Water Process tends to produce the most flavorful coffee, Ristenpart says, because its good at removing caffeine and without stripping other flavorful compounds from the beans. But its also more expensive and difficult to produce at scale. For this reason, Ristenpart says, youll typically find it used on higher-end coffees, such as Blue Bottle.
None of these methods scrubs the bean of caffeine completely. While the Food and Drug Administration requires that at least 97 percent of caffeine be removed, some decaffeinated coffees can still contain between 3 and 12 mg of caffeine per cup.
