What Is Decaf Coffee
What exactly is decaf coffee? Decaf coffee stands for decaffeinated coffee, of course. Its coffee that has virtually all of the caffeine removed from it. The three processes that remove the caffeine from the coffee bean are through the extraction of water, solvent and/or carbon dioxide. As for which method is best, lets take a look.
The two current methods of decaf coffee are the Swiss water method and carbon dioxide extraction method. The first process is called the Swiss water method. This method was invented in the 1970s. It uses only water and osmosis to remove the caffeine from the coffee beans. The coffee beans are soaked for many hours in water, which helps draw out the caffeine. The next step in this process is that the caffeine-rich water is pretreated through a pretreated charcoal bed to remove the caffeine.
The carbon dioxide method is probably the healthiest method for caffeine removal because its able to remove caffeine without any harsh chemicals or solvents. Another benefit to the CO2 extraction method is that it tends to keep its infamous flavor profile and aroma. Both the Swiss water method and CO2 extraction method do lose some of the volatile coffee oils, but at the end of the day, theyre chemical-free, which is a big plus.
How Much Caffeine In Decaf Espresso
Some people drink espressos every day and wonder how much caffeine they are consuming with their decaffeinated beans. To find out just how addicting it can feel when deprived for too long, we researched online sources on this subject to see what information was available. Most Starbucks cups contain about 100 milligrams each ounce or 30-45 mg per fluid oz . A grande at Starbucks contains 300 mg, which means two shots! This will depend on whether your preference is an Americano vs. Espresso, but both have about double the typical consumption from regular. So how much caffeine in decaf espresso? The amount of caffeine in different types of coffee varies widely due to how the coffee is prepared, including such variables as roast date, source/variety of bean, bean blend, and type of preparation method. In general, though, caffeinated coffee offers between 70-150 milligrams per eight-ounce cup. Decaf coffee contains 520 mg per eight-oz cup, and herbal ‘coffee’ has around 23 mg per eight-oz cup.
How Decaf Coffee Is Made: Processing And Roasting
Its helpful for decaffeinated coffee drinkers to understand how decaf coffee is made. When we raise this question, it is regarding the decaffeination process and not how to brew a cup of decaf coffee. There are different processing methods used to extract the caffeine from harvested green coffee beans.

Who Should Choose Decaf Over Regular Coffee
Theres a lot of individual variability when it comes to tolerance for caffeine. For some people, one cup of coffee can be excessive, while others may feel fine with more.
While individual tolerance may vary, healthy adults should avoid over 400 mg of caffeine per day. This is roughly the equivalent of four cups of coffee.
Increased consumption can lead to increased blood pressure and lack of sleep, which can increase the risk of heart disease and stroke .
Excess caffeine may also overwhelm the central nervous system, cause restlessness, anxiety, digestive problems, heart arrhythmia, or trouble sleeping in sensitive individuals.
People who are very sensitive to caffeine may want to limit their intake of regular coffee or switch over to decaf or tea.
Those with certain medical conditions may also require caffeine-restricted diets. This includes people who are taking prescription medications that can interact with caffeine .
Additionally, pregnant and breastfeeding women are advised to limit their caffeine intake. Children, adolescents, and individuals diagnosed with anxiety or who have trouble sleeping are advised to do so as well (
How Decaf Coffee Is Made
Caffeine is removed from coffee beans while they are green. Green coffee beans are beans that have been harvested, removed from the fruit and dried but have not yet been roasted. Once green coffee beans are ready for decaffeination there are a few different methods for removing caffeine in use today. Solvent-based methods use chemicals like Ethyl acetate or Methylene chloride to remove caffeine while the Swiss Water® process requires just water, time and temperature.

Is Decaf Coffee Good Or Bad For Health
This is a broad question with many factors to consider. One important factor is how sensitive you are to caffeine in general. To explore deeper, we all possess this specific enzyme called CYP1A2, which essentially dictates how well we metabolize caffeine. For instance, if you metabolize caffeine more slowly, you will be impacted more intensely by caffeine than someone who metabolizes caffeine faster. How well you metabolize caffeine dictates how much caffeine you can consume and tolerate.
Another rather fascinating perspective to decaf coffee when compared to caffeinated coffee is that it wont affect the chemical called adenosine in your nervous system. Adenosine helps modulate your sleeping and waking cycles. When youre awake throughout the day, adenosine accumulates in the brain. As the day carries on, you begin to feel drowsy and sleepy, thus sending signals throughout our body that its time for rest and recovery. When you consume caffeine, it binds to adenosine receptors. This binding results in your brain not detecting adenosine, thus keeping brain activity engaged and alert. This is why you hear how caffeine consumption can disrupt our circadian rhythms.
One last aspect of decaf coffee to consider is that when it comes to coffee enemas, decaf coffee isnt nearly as effective for the enema because the caffeine, theophylline and theobromine are what stimulate the relaxation of smooth muscles, causing dilation of blood vessels and bile ducts.

Is decaf coffee harmful to health? Decaffeinated coffee, or decaf, is similar in taste and appearance to regular coffee but contains very little caffeine. There is no evidence to suggest that drinking decaf is bad for a persons health, and it may even share some of the health benefits of regular coffee.
How Is Decaffeinated Coffee Made
Coffee = caffeine. Caffeine = energy boost.
But not everyone who drinks coffee likes the effect of caffeine on their day-to-day existence or simply due to health reasons are unable to consume.
These people luckily have an option in the form of decaffeinated coffee. But what does this mean? And how do they remove caffeine from coffee?
Lets start off by confirmed that, yes, coffee does contain a good amount of caffeine, but contrary to what you thought coffee actually has less caffeine that tea.
But thats not exactly correct, yes, tea has more caffeine in an unbrewed dry leaf form on average. But coffee has more in a brewed form.
On average a cup of tea provides 40mg vs 105mg in the average cup of drip coffee, so just over 2 ¼ cups of tea equal the caffeine boost of an average cup of coffee.
Granted this doesnt take into account the beans, length of brew time and a few other key factors, its at least a solid indication of the differences between the two hot drinks.
So if we have to get rid of this theoretical average of 105mg per cup of drip coffee, how are we going to go about it?

What Are The Health Benefits Of Drinking Decaf Coffee
There are several reasons why people may choose to drink decaf coffee. First, many of the antioxidants are preserved despite the decaffeination process. Therefore, a lot of the health benefits of drinking caffeinated coffee remain intact even if the caffeine itself has been removed.
Some people decide to drink decaf coffee to illuminate the side effects of drinking caffeine regularly. Caffeine can overwhelm the nervous system. This can create digestive issues, anxiety, and restlessness.
Furthermore, if caffeine is disrupting your sleep at night, you may want to switch to decaf coffee instead.
Finally, understand that decaffeinated coffee still contains small amounts of caffeine. No procedure is perfect and a cup of decaffeinated coffee may still have a few milligrams of caffeine. If you see coffee labeled as decaf, approximately 97 percent of the original caffeine content was removed.
This means that decaf coffee may still have two to three mg of caffeine present. Decaf coffee from coffee shops could have more caffeine present.

Are The Methods Used To Decaffeinate Coffee Bad For Me
Many of us drink coffee on a daily basis, but not everyone wants the caffeine boost that goes with it. These days decaf options are everywhere, even in posh coffees and with rare bean varieties, but many people are concerned that the methods used to remove the caffeine could be bad for our health.
Coffee naturally contains caffeine so to make decaf youve got to take the caffeine out of the coffee bean. The difficulty is removing the caffeine without removing all the flavour, which is why decaf has historically developed a bad reputation for the quality of its taste.
There are three main ways to decaffeinate coffee and they all start with the green, or unroasted, coffee bean. The first step is to get the caffeine out and this is usually done by soaking the beans in water which allows the caffeine, along with lots of the flavour, to dissolve out.
At this point chemical solvents – methylene chloride or ethyl acetate – can be used to remove the caffeine from the water. This can be done either by adding the solvent to the coffee/water mix or by removing the water from the beans, and then adding the solvent to it .
In either case, the solvent with its dissolved caffeine is then removed from the water. At this point the flavours remaining in the water need to be returned to the beans, and thats done by evaporating the water away to leave the flavours behind.
Your Complete Guide To How Decaffeinated Tea Is Produced
Caffeine occurs naturally in tea. For tea to be considered decaffeinated, the caffeine has to be removed. The tea industry uses 3 main methods to remove caffeine from tea leaves. Tea makers choose either the Carbon Dioxide, Ethyl Acetate or Methylene Chloride method. The method you prefer is a personal decision.
First, an important distinction. Decaffeinated tea and caffeine-free tea are not the same. Decaffeinated tea is made from actual tea leaves. All of the caffeine can never be removed from tea leaves and a small amount of caffeine remains, usually under 2%.
Meanwhile, caffeine-free teas are not made with actual tea leaves and do not contain any caffeine. The teas are herbal and include such varieties as chamomile, mint, hibiscus, rooibos and the like. Herbal teas really are 100% caffeine-free because they are made with herbs, spices and similar items and do not contain any actual tea leaves.
In the US, federal regulations dictate that decaffeinated products must have less than 2.5% caffeine. Most decaffeinated teas contain less than this amount.
Tea is more delicate than coffee so caffeine removal has to be done with caution. Since tea companies do not put the decaffeination method on the package, it can be difficult to find out. At teadog.com, we have obtained this information and included the decaffeination method for every tea we offer.

Does Decaffeinated Coffee Have Risks
While experts agree that the Swiss Water Process and liquid carbon dioxide dont introduce any health risks, methylene chloride is controversial in some coffee circles.
When inhaled in small doses it can cause coughing, wheezing, and shortness of breath. At higher doses, it can cause headache, confusion, nausea, vomiting, dizziness, and fatigue, and has been found to cause liver and lung cancer in animals.
In 1999, however, the FDA concluded that the trace amounts you get in decaf coffee are too minuscule to affect your health. The agency strictly limits its presence to no more than 10 parts per million, or 0.001 percent, of the final product.
Coffee producers will sometimes say that beans decaffeinated with ethyl acetate are naturally decaffeinated because the compound is naturally found in some produce. But as with methylene chloride, the ethyl acetate is typically produced synthetically and carries some risks at high doses.
The bottom line, Ristenpart says, is that the solvents used in the decaffeination process today are much safer than they used to be, and they are generally found on beans only in trace amounts.
The Directsolvent Based Process
In this method of decaffeination the beans are steamed for about 30 minutes in order to open their pores. Once the coffee beans are receptive to a solvent, they are repeatedly rinsed with either methylene chloride or ethyl acetate for about 10 hours to remove the caffeine. The caffeine-laden solvent is then drained away and the beans are steamed again to remove any residual solvent.
Most of the time the solvent of choice in this method is ethyl acetate, so youll often see it referred to as The Natural Decaffeination Method or The Ethyl Acetate Method.
Typically, if a process is not named for a decaffeinated coffee, it has been treated by either the direct or indirect solvent methods.

Which Decaf Should You Choose
Experts say you shouldnt be concerned about the chemicals used in the decaffeination process. But if you are looking to minimize your exposure, you might want to know which decaffeination method was used on a particular bag.
This may be more challenging to find out than you think, Ristenpart says, because there are no specific labeling rules that require disclosing exactly how coffee was decaffeinated.
If consumers want to be sure that synthetic solvents werent used to decaffeinate, they should look for the organic seal, says Charlotte Vallaeys, Consumer Reports senior policy analyst and food-label expert. That seal prohibits not only pesticides, but chemical solvents during processing, too.
If your beans are not organic, ask your supplier which method was used, either in person if youre buying local or over the phone. If it used the solvent process, there are probably trace amounts of chemical residue on the beans.

A Short Explanation Of Swp
This particular method of decaffeination is different from what weve so far seen in that it does not directly or indirectly add chemicals to extract the caffeine. Rather, it relies entirely on two concepts, namely solubility and osmosis, to decaffeinate coffee beans.
It begins by soaking a batch of beans in very hot water in order to dissolve the caffeine. The water is then drawn off and passed through an activated charcoal filter. The porosity of this filter is sized to only capture larger caffeine molecules, while allowing smaller oil and flavor molecules to pass through it.
Consequently we end up with beans with no caffeine and no flavor in one tank, and caffeine-free flavor charged water in another tank.
And heres where the magic happens. The flavorless caffeine-free beans are discarded, but the flavor rich water is reused to remove the caffeine from a fresh batch of coffee beans.
Since this water already is saturated with flavor ingredients the flavors in this fresh batch cant dissolve only caffeine moves from the coffee beans to the water. So the result is decaffeination without a massive loss of flavor.
Coffees decaffeinated by this method are always labeled as SWISS WATER Decaf.
This method is almost exclusively used for decaffeination of organic coffee.
Coffee decaffeinated using the environment-friendly Swiss Water Process undergoes regular caffeine level audits to ensure compliance to 99.9% caffeine-free.
