Decaffeinated coffee has gained popularity among coffee drinkers. Its popularity is due to it being a great coffee alternative for those sensitive to coffee or those trying to reduce their coffee consumption. It is also the best alternative as it tastes, smells, and looks the same as regular coffee. 

Although decaf coffee has been stripped of its caffeine content, it is not caffeine-free but has a reduced amount of caffeine. To know more about what decaf coffee is, how it is made, how much caffeine is in a decaf cup of Joe, its possible side effects, and the different decaffeination processes, read along! 

What is Decaf Coffee?


Decaf coffee is the short form of decaffeinated coffee and is coffee that has been processed to remove at least 97% of its caffeine content.

For coffee to truly be decaffeinated, the caffeine content should have a maximum of 0.1 grams for every 100 grams of green beans. During the decaffeination process, additional chemicals are used to help in speeding up the process.

The additional chemicals we will discuss help minimize the loss of non caffeine compounds to preserve coffee's distinctive flavor, so you can still enjoy your decaf coffee like it is caffeinated.

Wondering if the decaffeination process is safe? Yes, it is! After the decaffeination process has taken place, the coffee beans are washed, steamed, and roasted at temperatures that ensure all the chemicals used evaporate.

The Decaffeination Methods Explained


There are several ways to remove caffeine from coffee beans. The most commonly used processes are the Swiss Water Process , Carbon Dioxide process, and using chemicals such as methylene chloride and ethyl acetate,

1. Swiss Water Process

In the Swiss Water Process of decaffeinating coffee, green coffee beans are soaked in hot water to dissolve the caffeine. Then caffeine is passed through a charcoal filter, which will be trapped in the filters as other flavor compounds pass through.

Caffeine is then flashed out with pure mountain water. The Swiss Water Process is a great decaffeination method that relies on osmosis to remove caffeine from green coffee beans.

2. Using Ethyl Acetate or Methylene Chloride Process

Another way to decaffeinate coffee is to dissolve caffeine content in beans by using ethyl acetate or methyl chloride. This process entails soaking green coffee beans in near-boiling water for about 10 hours.

Using Ethyl Acetate is considered a "natural" process because ethyl acetate occurs naturally in nature and helps ripen fruits such as apples. However, it is important to remember that other components, such as oils and other flavor elements, are extracted through this method.

3. Carbon Dioxide Process

To decaffeinate using the CO2 process, coffee is placed in a CO2 chamber where CO2 absorbs the caffeine in the beans. In this process, presoaked coffee beans are placed in an extraction vessel, and the extractor is filled with CO2 at a pressure of 1000 pounds per Square inch. Carbon dioxide acts as a solvent and dissolves the caffeine from the coffee beans. 

How much caffeine in Decaf Coffee?

How Much Caffeine is in Decaf Coffee?


Depending on the brew method and coffee types, you may see a cup of decaf containing 2 to 3 mg of caffeine. This is much lower than 65 to 115 mg in caffeinated coffee because decaffeination removes 97% of caffeine.

A 236 ml cup of decaf coffee contains 7 mg of caffeine, while a regular cup of coffee contains 70-40 mg. The two examples show that decaf coffee contains some bit of caffeine as it is impossible to remove all caffeine from coffee beans without affecting their flavor and other components.

What about espresso? You may be wondering how much caffeine in decaf Starbucks espresso contains; well, 1 oz decaf espresso contains between 4 mg of caffeine per shot.

Decaf Coffee and Flavor


The decaffeination method directly impacts the taste and smell of your cup of Joe, and you may notice a color change, while the taste and smell may become milder.

After harvesting green coffee beans and drying the beans, decaffeinating coffee begins with soaking unroasted coffee beans in water and other chemicals.

Is Decaf Coffee Caffeine Free?


When you are trying to reduce your caffeine intake, it is worth asking if decaf coffee is caffeine free. Well, decaf coffee has 97% of its caffeine content stripped off. The result is a brew containing about 6 mg of caffeine for every 8oz serving.

Are you trying to avoid caffeine? If you have any concerns, it would be best to get your doctor's opinion on drinking decaf coffee. Also, the FDA recommends that adults limit methyl chloride concentration in decaf coffee to no more than 10 ppm (parts per million).

If under medication or have caffeine sensitivity, it may be best not to drink coffee and decaffeinated coffee blends.

What is the Difference Between Decaf and Regular Coffee?


The difference between decaf and regular coffee is that decaf has been stripped of the caffeine that makes up the majority of its content. While decaf coffee is still a very popular choice for those minimizing their caffeine intake, it's certainly not for everyone because decaffeinated coffee lacks the same robust flavor.

Caffeine is a stimulant that can be consumed in small amounts but is also highly addictive. People with trouble sleeping or other health problems may want to avoid caffeine altogether.

You may argue that caffeine in coffee helps improve alertness and energy levels. However, too much caffeine can cause side effects, such as anxiety, insomnia, and irritability. It is the reason why decaf coffee is recommended for pregnant women because they are vulnerable and need to watch their caffeine intake. So it is a safe and easy fix when the pregnancy cravings kick in.

YOU ARE NOT BEING CLEAR ABOUT CAFFEINE CONTENT IN YOUR DECAF COFFEE. FOR EXAMPLE, THIS SITE SHOWS A PHOT0 OF A DOUBLE DARK CHOCLATE MOCA DECAF BAG HEADLINING “SWISS WATER PROCESS”. BUT THE BAG YOU JUST SENT ME DOES NOT SAY THIS. IT HAS BEEN OMITTED. WHY? SOME OTHER METHOD?. MY UNDERSTANDING IS THAT SWISS PROCESS IS MORE EFFECTIVE IN REMOVING CAFFEINE, WHICH IS DESIREABLE FOR ME. PLEASE ADVISE. JUST WHAT METHOD DO YOU IN FACT USE??
ALSO, THE LONG PARAGRAPHS ABOUT CAFFEINE SOUND LIKE THIRD PARTY INTERNET BABBLE, NOT SOMETHING YOU WROTE YOURSELF. STAY TRANSPARENT AND CLEAR IF YOU EXPECT US TO SEE LIFEBOOST AS A SUPERIOR COMPANY AND PRODUCTS THAT DESERVE THE PREMIUM PRICE YOU EXPECT. IF I HAVE TO QUESTION YOUR MOTIVES OR FORTHRIGHTNESS, I’M OUT.

Hi,

I purchased your decaf coffee last month. I would like to know if you add any chemicals during the decaf process or if it’s truly all natural, without any chemical ever being added during the entire process?

Thanks,
Aditi
