Green Tea First, some background on green tea: Green is chock full of antioxidants and other nutrients, thanks to chemical compounds found in the leaves called catechins. To maximize your exposure to catechins, and thus extract the greatest health benefits from your cup of tea, the whole buds and young leaves of most loose leaf teas are superior to broken leaf pieces, called fannings and dust, which are found in many bagged varieties. So why might loose leaf tea leaves be better? Catechins degrade over time. Tea bag tea may have been stored longer than the loose leaf green tea, which means fewer catechins present. Catechins concentrations are higher in the whole leaf than in the pieces and dust (because the greater surface area of the smaller pieces means more surface area is exposed to light and air, which results in faster loss of nutrients). These whole pieces are more likely to be found in loose leaf tea. Tea bags can absorb some catechins. This means you may lose more nutrients in the bag than you do if the leaf is loose. However, drinking green tea from tea bags can also have its advantages: Green tea in the tea bags is more likely to be dust and fannings and because of this, there is more interaction between the tea and the water (the smaller the tea leaf, the more surface area is exposed to the water, causing more infusion of the tea nutrients). Tea bag material varies with the tea company. Some tea bags are biodegradable and interfere less with tea brewing than others, and may also leach fewer nutrients out of the tea. Is your green tea organic? Drinking organic green tea ensures fewer chemicals and pesticides will make their way into your hot cup. How fresh is your tea? Catechins are lost the longer the green tea is stored. The fresher the leaf, the more nutrients will be present in the leaf. How are you storing your tea and how was it stored before it found its way to you? Tea should be stored in a sealed container as air tight as possible in a cool, dark place. The freshness issue, by the way, is not a concern for all teas. In fact, some teas improve with age, much like wine. But green teas benefits are more likely reaped with a fresher leaf. When checking for tea leaf freshness, keep the following guidelines in mind: Does the tea smell very green or does it smell smoky or even moldy? Generally, fresh green tea smells very green or refreshing, while the older stuff is likely to smell smoky, stale or moldy. Has your tea been stored near light, heat, moisture, or strong odors? Exposures to these things will cause tea leaves to degrade more quickly – so dont store your tea in glass canisters, over your stove, in your refrigerator, or with your spices. Have you checked the leaf color and tea taste? Light green colors suggest higher green tea quality than golden or brown colors. Also, the tea should also taste light, not bitter, when fresh.
