Theme - Tea oxidation

„Although green tea does not raise the metabolic rate enough to produce immediate weight loss, a green tea extract containing polyphenols and caffeine has been shown to induce thermogenesis and stimulate fat oxidation, boosting the metabolic rate 4% without increasing the heart rate.“

„Ripened or aged raw pu-erh has occasionally been mistakenly categorised as a subcategory of black tea due to the dark red colour of its leaves and liquor. However, pu-erh in both its ripened and aged forms has undergone secondary oxidization and fermentation caused both by organisms growing in the tea and free-radical oxidation, thus making it a unique type of tea. This divergence in production style not only makes the flavour and texture of pu-erh tea different but also results in a rather different chemical makeup to resulting brewed liquor.“

„Unlike green tea produced in china which is dried with hot air after the pan-frying stage to completely kill enzyme activity, leaves used in the production of pu-erh are only pan-fried and thus a small amount of enyzmes are left which contribute a minor amount of oxidation to the leaves during sun-drying“
