Antioxidant benefits in other types of green tea

Green tea, which is the latest trend amongst many health conscious people, has many grades based on the usage, and the method of preparation. After knowing the various benefits of this wonder drink, and to get the full benefits of green tea, there originated a special variety of tea called ‘matcha’.

Matcha is a special type of powdered tea grown and produced in Japan. During ancient Japanese period, monks brought the idea of powdered tea, and this eventually evolved into the traditional chanoyu ceremony. The tradition of drinking powdered green teas is still a popular tradition in Japan even though the cultivation and production methods are very costly.

Matcha is produced from the same plant camellia sinensis. Only the process of producing matcha varies from regular green tea where the leaves are unfermented, steamed and dried, oolong tea where the leaves are partially fermented, and black tea which is fully fermented.

Camellia sinensis have varieties, and some of them produce better matcha than other varieties. The highest grade matcha come from one of three Japanese varieties (samidori, okumidori, and yabukita in Japanese)These three varieties of the tea plant have been explored, selected for, and grown in Japan for more than 900 years.

Matcha green tea powder is more powerful and packed with a tremendous amount of anti-oxidants (EPCG), phenols, vitamins, minerals, and amino acids.Check the nutritional and chemical composition of matcha here Matcha has 137 times the catechin (antioxidants) found in other green teas. Matcha stands topmost in the ORAC (1384) scale. Unlike, the usual steeped green teas brewed, matcha tea brewed without steeping has a full range of benefits and that is mainly because you consume the complete tealeaves. In steeped tea, more, that 50 % of the valuable antioxidants and minerals are lost along with the tea leaves making the drink less potent.

Ceremonial is the topmost grade available in the market. Only the top two tender leaves of the tea plant are plucked to prepare this grade of tea. This grade normally used to prepare the traditional Japanese drink. Many top sellers sell ceremonial grade matcha green tea powder. Each one varies in quality (the origin of the tea leaves) and cost. An analysis of cost is given in one of our reviews. Culinary is a lower grade. Here the rest of the leaves, buds, and stem are used to prepare the tea powder and because of this, it is usually less expensive. It is best used as an ingredient in food and/or beverages such as smoothies.
