In today's busy world, when we are looking for ways to enjoy a moment of peace and relaxation, tea has become a favorite companion for many of us. However, for some, the caffeine found in traditional tea can be a problem. Fortunately, there are alternatives, such as decaffeinated teas, that allow you to enjoy the taste of tea without having trouble falling asleep. Get inspired to enjoy long summer evenings with our selection of teas.

All teas, which come from the Camellia Sinensis plant, naturally contain caffeine. This substance acts as one of the many defense mechanisms that help us cope with a difficult work week. Even though tea leaves contain more caffeine per kilogram than coffee, we don't have to worry about overdose. It is unlikely that we would be able to drink a kilogram of tea at once. The amount of tea commonly consumed is much smaller. In fact, we would have to drink three cups of tea to contain the same amount of caffeine as one cup of coffee.

An interesting fact is that different parts of the tea leaves carry different amounts of caffeine. Most of the caffeine is found in the small buds of the tea plant. Green tea contains slightly less caffeine than these buds, while black tea has even less. In the preparation of black tea, the tea leaves are steeped for a longer time than in green tea, which complicates the matter somewhat. The process of decaffeination results in the almost complete removal of caffeine from the tea leaves.

However, it is important to note that beverages labeled as "teas" without caffeine are not actually true teas, but mixtures of herbs, flowers, spices, and dried fruits. If such a beverage is composed of only one species, such as mint , we call it tisane to make it clear that it is not a traditional tea from the tea plant.

Method of decaffeinating tea with carbon dioxide (CO2)

The method of decaffeination of tea using carbon dioxide (CO2) is a sophisticated way to remove caffeine from tea leaves without compromising their taste quality. This process uses CO2 at high pressure and temperature. Under these conditions, carbon dioxide acts as a liquid solvent, attracting caffeine and removing it from the tea. This leaves the aroma and flavors of the tea intact. This method combines technological advances with the preservation of the taste and quality of the tea, allowing us to enjoy the tea experience without excessive caffeine.

Decaffeination method with ethyl acetate

The ethyl acetate decaffeination method is a method of removing caffeine from the tea contained in our tea bags. In this process, the caffeine binds to ethyl acetate molecules, which are then removed. Our customers prefer this method for our tea bags.

There are two other decaffeination methods for hard coffee beans that are not suitable for fragile tea leaves. These are the water treatment method, also known as the "Swiss water method", and the methylene chloride method.

Many tea lovers believe that steeping their favorite caffeinated tea, pouring out the water, and then steeping it again will reduce the amount of caffeine in the cup. Unfortunately, this is a bit of an old myth. Studies show that tea releases caffeine in about 8 minutes. This method is not recommended because it dilutes the flavor of the tea.

No matter what your reason for drinking decaffeinated tea , whether it's a doctor's order or insomnia, you'll find teas you'll love at Harney & Sons.
