23 Best Naturally Decaffeinated Tea Brands in 2022

If you’re as sensitive to caffeine as I am, even a small cup of tea before bed can have you tossing and turning all night. Many of the decaf tea options from the grocery are no good in my book because they use harsh chemicals during the decaffeination process. The most natural methods of decaffeination are Swiss Water and CO2 with the CO2 method being much more common. Unfortunately, the decaffeination method used is not required to be listed on product packaging in most countries including the US so you’re mostly in the dark when shopping to find naturally decaffeinated tea. I’ve dug through many brands sites and emailed countless others to find the brands and specific products that do use natural decaffeination techniques.

Naturally decaffeinated green tea is more common than black or white. Even some big manufacturers like Bigelow have begun to use CO2 decaffeination for their green teas.

There is only one water processed decaf tea brand on this list. Water processing is the preferred method for decaffeinating coffee naturally but the method doesn’t work as well for tea which is much more delicate than coffee–especially for the higher end loose leaf tea blends most of these brands sell. Water processed decaf tea is known to destroy a lot of the flavor in the tea and is commonly thought to taste “watered down.”

All of Stash Tea’s decaffeinated products call the process “naturally decaffeinated” but don’t mention the actual method used. Only the Early Grey product claims to use a “European process” which isn’t standard terminology from my research. I’m not quite sure what this method is but I’d imagine it is some variation of CO2 processing.

How is tea decaffeinated?

Ethyl Acetate

Ethyl acetate is a naturally occurring compound created from the fermentation of sugarcane. Although this technically makes it “natural,” for efficiency the ethyl acetate used commercially for decaffeination is entirely synthetic. Some people are concerned because ethyl acetate is also commonly used as industrial solvent and is even found in nail polish remover– not something you’d like to find in your morning tea or coffee!

The process involves soaking the leaves in ethyl acetate for about 24 hours to allow the caffeine molecules time to bond with the ethyl acetate. It’s the most common decaffeination method for both tea and coffee because it’s cheaper than water or CO2 processing at a mass scale.

Water processed

Water processing using the Swiss method is almost never used for tea. The method involves soaking the tea (or more commonly coffee) in hot water. Caffeine is soluble in water and will be stripped away from the tea with time. However, many of the important particles that give tea flavor and aroma are also water soluble and will also be stripped from the tea. The solution is to filter the water through a carbon block filter to create an flavor and aroma rich extract which is added to the next batch to preserve the flavor.

Swiss water processing is the most effective method for decaffeinating coffee and is preferred for being entirely chemical free. However, tea is too delicate to withstand hot water and degrades during the process. The Swiss water method virtually unused by tea manufacturers.

Carbon Dioxide

The gold standard of tea decaffeination techniques. It preserves the most flavor of any method while only using Carbon Dioxide, a naturally occurring molecule in the air you breathe. The process works a lot like the water processing method except using compressed CO2 as the soaking solution instead of water. Compressed CO2 is in a gaseous state and therefore less harsh on the tea leaves.
