Did you know the international tea industry classifies the tea in most tea bags as DUST? the lowest leaf grade quality. It is also called Fannings, fine grainy particles left over from the processing of the larger and broken leaf.
Loose leaf Tea contains far less caffeine than filtered coffee, but caffeine is regarded as integral to a quality cup of tea. White tea has minimal caffeine, less than Green, Green has less Oolong, and Oolong has less than Black. Many variables affect caffeine levels. On average, Black tea is about 50% to 60% less caffeine than filtered coffee, Green Tea around 70% less caffeine than coffee and White Tea around 90% less caffeine.
If you love (Tour de Tea!) tea and want to minimise your caffeine, pour out the first infusion after about 30 seconds and do another. Most of the caffeine exits the tea in the first 30 seconds. Herbal teas, Rooibos and Fruit Tisanes are all guaranteed caffeine free, and are high in anti-oxidants.
