All Tea comes from the same plant (Camellia Sinensis), but the difference is in the processing. Green tea is dried, but not fermented. The shorter processing gives green tea a lighter flavor. It also helps keep all the beneficial chemicals intact, which is why green tea is so good for you. Green was given its name because the tea leaves retain most of their color; it is as close to the natural state of the Camellia Sinensis leaf as is possible. 

After being picked the leaves are immediately steamed or fired (heated.) The leaves are allowed to wither only slightly after picking and are then rolled and dried. This kills the fermentation enzymes so none takes place due to the stopping of any oxidation in the leaves. After withering, the leaves are pan fried or fired but not fermented preserving the nutrients and vitamins found in green tea. 

The last step is to roll the leaves and dry them one last time for its final shape. Many finer teas are still rolled and shaped by hand. This  subsequent rolling of the leaves allow the tea to fully release its aroma and taste that has made green tea the most popular tea in Asia. That is why the leaves are green, the liquor so light and the flavor so vegetal or mild

Don't expect green tea to taste like your regular tea. All the different kinds of green tea have different flavors, but they do have a taste in common. The flavor of green tea can be described as: fresh, light, green, or grassy. Some varieties of green tea have a bit of sweetness to them, and some are a little astringent. The health benefits of green tea are seemingly endless. Since the leaves are not fermented, the taste is pleasantly fresh and herbal.

Green tea is rapidly gaining popularity in the Western Culture due to its health benefits. It is high in nutrients, anti oxidants and minerals.  It has low caffeine.  Green Tea also contains Vitamin C, which helps strengthen our immune system and promote good health. It has fluoride, which helps strengthen our bones and prevent cavities by protecting our teeth. 

Green Tea should be appreciated for the subtler taste and light aroma and color.
