What You Should Know about Tea

Tea is a drink made by steeping the leaves, buds or twigs of the Camelia sinensis plant for about five minutes.  What determines its color is on how it is fermented. The most fermented type is black tea, but fermentation stops on any tea when it is fully dried.

It has no calories, yet it contains loads of phytochemicals and methylxanthines, a chemical group, including caffeine (but much lower than coffee has).  It is why tea is considered a healthier alternative than coffee, especially for its loads of phytonutrients.

Hibiscus and green tea are two of the best antioxidant sources, which may elevate its level in the bloodstream in almost just an hour. But dandelion tea is what contains the most antioxidants among herbal teas.

Tea Information

Most teas come from Camellia sinensis, but there are so many types of teas – each with a distinct aroma, taste and color.  Just like coffee, each harvest changes because of rainfall, climate and other weather factors. It is also the reason tea coming from the same garden or plantation taste differently from year to year.  Also, a specific harvest may have a different character based on how the leaves are processed.

There are also several tea categories, including red, white, fermented, oolong, black and green. Categories refer to the level that the tea is fermented or oxidized.

When a tea is less oxidized, the lighter and gentler it will have regarding aroma and taste. Oppositely, those highly oxidized will result to an earthy fusion or a dark deep reddish brown color.

On the other hand, white teas will normally produce a pale or yellow green drink. However, there are also exceptions, such as in the case of gyokuro, which is the highest grade in green tea that will produce an intense flavor versus the toffee-like drink coming from the Sri Lankan black tea.

But then, it must be noted that infusions, such as linden or chamomile flower, are not real teas because they are not from the Camellia sinensis.
