This method also is the most effective at helping the tea maintain its flavor profile and removing the caffeine content without altering any potential health benefits.
This method is nontoxic and generally more expensive, but it's the best at preserving the composition of the tea. Tea leaves are subjected to high pressure and high temperatures until the carbon dioxide reaches what is termed the super-critical state. At this point, the carbon dioxide transforms into a solvent and attracts the caffeine molecules in the leaves.
The flavor molecules within the leaves are larger than the carbon dioxide and caffeine molecules, which is why they are unaffected by this decaffeination method. Featuring a low toxicity and a lower cost than alternative methods, this is a popular process, although it is known to alter flavor profiles of tea. Tea leaves are soaked in ethyl acetate to remove the caffeine. After the caffeine is removed, it is near impossible to remove the ethyl acetate from the loose tea leaves.
This results in an altered flavor that is often described as having a chemical or bitter taste. This method is similar to that of ethyl acetate, but a different chemical is used to extract the caffeine.
Tea decaffeinated using this process maintains the natural flavor profile better than those decaffeinated using ethyl acetate 1. However, there can still be residual amounts of the methylene chloride, a chemical linked to cancer and birth defects. Some countries ban the importation of teas decaffeinated using this method and the European Union has placed limits on the allowable amounts of residual methylene chloride present in teas.
This method is more popularly used when it comes to decaffeinating coffee beans, but some tea brands use it for loose leaf teas as well. The tea leaves are soaked in water, which is then passed through a carbon filter to remove the caffeine. The water is then added back to the tea leaves to develop flavor. The water method often results in watery flavors and does not maintain the potency of breakfast black teas or other strong teas well.
One of the most common questions people ask before switching to decaf is whether or not they will still be able to reap the health benefits of tea. The decaffeination process removes not only caffeine, but also polyphenols and some antioxidants, meaning decaf may not be as potent as regular tea when it comes to health benefits.
That doesn't mean that decaf tea is a total waste of time or that it doesn't offer any health benefits at all. According to a study, flavanol content in decaf tea was anywhere from Antioxidant values were also lower, but were still present in large amounts.
So while there is a reduction in flavanol and antioxidant content, there is still enough present to offer potential health benefits 2.
The biggest benefit of decaf tea is that you can consume it at any time of the day, even in large quantities, without worrying about getting the jitters or having insomnia. You don't need to drink only decaf brews unless you have sensitivity to caffeine or another medical, religious or personal reason to take into account. You can mix it up with a decaf herbal blend before bed to help you sleep peacefully and a rejuvenating Darjeeling, Assam, Ceylon or white tea in the morning to jump start your day.
Drinking caffeine-free teas doesn't mean you have to sacrifice taste or aroma. You can still enjoy a variety of different tea blends, even if you are avoiding caffeine. Ginger tea is made by infusing the root of the ginger plant in hot water. No tea leaves are added to this tea recipe so you don't have to worry about any caffeine.
Spice up your ginger tea by adding a slice of lemon and a dash of honey to play off the spicy bite of the ginger root. Lemon ginger tea offers a balanced flavor that features spicy notes and smoother tangy notes. Just because you want to go caffeine free doesn't mean you have to give up your favorite English breakfast tea.
Thanks to creative tea masters, you can get your hands on a decaffeinated British Earl Grey tea by opting for a rooibos Earl Grey. Made from the red rooibos plant in South Africa, this Earl Grey is brewed using a red tea that doesn't contain any caffeine. It's still flavored with bergamot so you'll get that delicious citrusy flavor without the jittery feeling. Hibiscus tea is an herbal infusion that brews into a brilliant magenta color. The tea boasts a flavor similar to cranberries with sweet and tart notes.

Methylene Chloride: Using this method, caffeine is removed by soaking tea leaves in methylene chloride directly or indirectly, by soaking the water used to remove the caffeine in methylene chloride and then returning the water to the tea for re-absorption of flavors and oils. It is a decaffeination process by which the molecules of caffeine bond to molecules of methylene chloride. It is believed that methylene chloride is not the best possible and healthiest method of decaffeinating, although this process is noted for maintaining more of the original flavor of the tea than other methods.
It is forbidden to import teas treated this way in some countries. The solution also used as a solvent where caffeine is extracted in the same way as with methylene chloride processing. Loose tea and tea sachets on the other hand are being decaffeinated using the Carbon Dioxide method described below.
It is also known as a natural method of decaffeination that allows for retaining the tea flavours and health benefits. 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. The Carbon Dioxide, or CO2, method is used only by a few brands. Clipper Tea, from England, is perhaps the best known proponent of the CO2 method. Clipper is one of the very rare tea makers to produce an organic and CO2 decaffeinated tea.
Taylors of Harrogate uses it for their Decaf Breakfast, but not for their Yorkshire Decaf, and it is not organic. Actually, CO2 is the most natural of the three main decaffeination methods.
Carbon Dioxide gives sparkling water its bubbles. Because CO2 is a naturally occurring element, it is the most ecologically-friendly method because no chemical solvents are used. But it is more expensive to decaffeinate teas with this method. Tea makers that use CO2 believe the method best maintains the natural flavor of tea. It is not the most popular decaffeination method, partly because of the cost. In this method, tea leaves are combined with CO2 and brought to high temperature and high pressure.
At this point, caffeine molecules in the tea become attracted to the CO2 and then removed. Caffeine molecules are small and flavor molecules are larger, which means the tea taste remains. For this reason, CO2 decaffeinated teas are believed to have the best tea flavor.
Often, teas decaffeinated using ethyl acetate are called naturally decaffeinated. The term is used because ethyl acetate is naturally found in many fruits. But, it is also used in nail polish remover among other items. Although it does occur naturally, the ethyl acetate used to decaffeinated tea is chemically manufactured. Is the ethyl acetate process actually natural?
