I never knew it when growing up but Camellia Sinensis is a common
ornamental shrub in the deep South along the coast. Jim Jenn wrote: And I must say that I have been succesful here in South Coastal Texas for most of what I have tried Eeeh hawww!!! Maybe the climate here will be good. Has anyone had any success in a US southern (subtropical) climate? And where can I obtain seedlings? Do they need grafting? Very cool job you must have done to get such sweet nice leaves even as the tree was dying. Wonder if the tree grew for many years how your harvest would be? Jenn |

Thanks in advance, George George There was a Chinese study done that take the same leaves and process them differently for green tea white tea oolong tea red tea black tea and yellow tea Guess what they found? Among all of them, green tea is found to have the most similar chemical composition to fresh tea leaves. It is a fascinating study. Which tea is less processed is really a matter of definition. Length of time? Green tea. Amount of oxidation? Green tea Alteration of chemical composition? Green tea Amount of heat applied? White tea And so on... You can defined your own least processed tea ![]() Have fun! Julian http://www.amazing-green-tea.com |

Looking at pictures of them online, but not in a tea field, they look familiar, and I do know I have seen some flowering camellias, So if you know they have been around, and I am more southern than the majority of the southern states (so. Tx) Maybe I will have a good chance to at least grow one just for the sake of it. Yeah, I think it would be pretty cool to have a tea tree. and All of you thanks for the tips on the tea tree!!!

Yeah I think Julian is right.
But it doesn't mean that least processed tea is the best. You should take your own needs and body situation into concern. For example, if you have really weak stomach, then green tea or white tea is not for you, you should go into oolong and black. If you are sensitive to caffeine, then black tea and oolong tea wouldn't be good choices, you should take green tea or white tea. Tea is really complicated...even people grow up in tea culture wouldn't master tea easily... oneone |

There's no reason to expect more caffeine in a cup of black tea than you'll find in a cup of green tea. This issue has been ventilated many times on RFDT, and nobody has yet provided evidence for greater oxidation leading to more caffeine. /Lew --- Lew Perin / And yet they feel more stimulating. It might be the taste itself, or it might be other stimulants that IIRC are present in tea. This isn't a simple matter, in my opinion. I feel that it's not only a matter of how strong of a stimulating effect you get but also that the effect is different in nature. For instance, coffee and to a lesser extent, black tea, will make me feel jittery, but not an oolong or a green tea. Crystal meth is probably like coffee, but even more so. |

With black teas, you often have pulverized teabag assam and ceylon teas that will have a stronger effect perhaps because caffeine is more readily released from tea dust. I'll never get the same effect from a black tea with large leaves like golden Yunnan, even if you use the same weight of leaves and brew 10 times longer. But, I imagine, if you made green tea into dust, it'll be close if not the same. /Lew --- Lew Perin / |

All japanese teas I tried smell and taste fishy. I may be insane, but the way I figure, I don't want fishy flavor anywhere near my tea.. but I've heard gyokuro can be good. Can anyone tell me if gyokuro is also fishy? No matter.. what I'll do is take a cheapo young hyson tea from specialteas (I think) and put it into mortar & pulverize it to bits. And *then* report back! /Lew --- Lew Perin / http://www.panix.com/~perin/babelcarp.html |

Oxidation - the pc term for fermentation in tea - does NOT affect the theanine level. "Oxidation" as a process in tea is strictly the enzyme catalysed oxidation of catechins to theaflavins mediated via Polyphenol-oxidase or PPO. Theanine being an amino acid is unaffected by PPO. Fermentation is however a whole lot more than just oxidation, hence my preference for the former term, as it includes post oxidation condensation and polymerization of theaflavins into many species of thearubigins - none of which processes requires any oxygen - nor have any affect on theanine level. There is potentially a slight reduction in theanine level during firing (drying) due to Maillard reaction of amino acids with sugars - but this should equally affect green teas.
