The Chinese playing field tea is a slow mushrooming woody plant that produces small, thin leaves. Usually cultivated from seeds, it has smaller number caffeine, go from 1% to 3% in dry weight.
The Indian black tea is a fast mushrooming woody plant that yields large, broad-brimmed leaves. Usually cultivated mistreatment the seedlike airing method, it contains more caffeine, travel from 3% to 5% in dry weight.
It is the industrial unit variety, not oxidation, that causes dark tea to have close to the twice over the caffein as playground tea.
But not all environment of the tea industrial unit have the self magnitude of alkaloid.
Leaf Style
Many broad class untried teas are ready-made from the bud and its nearby two leaves. These protective shoots are the sweetest, tastiest and healthiest.
They are the richest in catechins, which contains all the antioxidants, and the sweetish and caller sample theanine, which calms and soothes the cognition. Unfortunately, they as well contain the most caffein.

It is no fortuity that the best untried tea from China (Longjing or Dragon Well) and Japan (Gyokuro) have one of the untouchable caffeine exultant.
Teabags have less leafy tea caffein content, and a poorer benignity to ignitor.
Black tea is made from larger, more than ripened leaves. This technique that a last position loose-leaf green can have as considerably alkaloid as black tea, sometimes even more.
Growing and Making Conditions
Now we are in the sovereignty of wavering.
The provincial increasing stipulations can force the untested tea alkaloid complacent. An oftentimes quoted instance is the Japanese Gyokuro, which is shaded distant from sun to wrap up its theanine and caffein complacent.
Other smaller amount lucid conducive factors are soil, clime and when the tea is harvested. Processing method, such as as annihilating and oxidation besides dramatic composition a cut. The longer the leaves are leftmost to wither, the greater the caffeine. But the longer they are port to oxidise, the inferior the caffeine.
Now you see why depending on who you ask, green tea caffein ecstatic can rise and fall from 8 to 75 milligrams a cup?
