But I want to ask you something, how is it possible that there are some (few) sellers, also known enough here on the forum, that are able to offer a more or less wide range of tea products from organic or low pesticide tea garden garden, whether it's Japanese green teas rather than Taiwanese oolong teas or pu-erh Chinese teas, and other vendors (the majority) that offer a more or less wide range of tea, but that none of these comes from organic or low pesticide tea garden garden.
It would seem then, that they are only two potential solutions, or the first lie, or seconds do not want to/can not offer such products.
In Japan and Taiwan it may be easier as both are modern countries, where people have access to good education and are wealthy enough to care about those issues, and chances are higher that when something that is offered as organic is indeed so. Nevertheless, if you look at the Fukushima power plant scandal, you still see that there is still much lacking in regards to environmental issues and transparency.
In China though - you can just hope that organic is organic indeed. There is a higher chance that when leaves from Pu Erh teas come from wild trees in far off gardens that they are indeed organic. But there is no real control. With boutique teas there is a higher chance that individual vendors and producers have more personal control over this. But teas will still go through factories to process. There is a higher chance that a producer, or vendor (if it his production) can find a factory whose standards of hygiene might be higher. But there is no guarantee.
In any of the larger factory teas there just is no guarantee at all. A vendor might visit a factory, but just cannot control the finished product, or guarantee that leaves are indeed from organic gardens. Often you cannot even trust that when a tea is labeled from a particular area, that leaves from that area are indeed used, and not only a small percentage, and the remainder from wherever the leaves were cheap.
In any of the stages of production there might be insects crawling into the leaves, a worker might smoke a cigarette while sorting the leaves, or chew on some sunflower seeds. Don't forget - China might be booming, but it still is a developing country with glaring discrepancies of wealth distribution and access to education. Hours are long and labor is cheap.
Just look how Pu Erh's are produced there. People are hired by farmers to pick the leaves, the leaves are left in the open to dry, transported to factories, where they are stored again in large heaps in warehouses. How can you stop a beetle or a fly getting in the the leaves, or some dirt getting mixed in?
Part of the charm of Chinese teas is that many teas are still hand processed in the traditional way, and not industrially processed.
Anyhow, while there are some Chinese teas that carry the label of organic, all we can do is hoping that this indeed so, as there is no real functioning government enforcement as in Europe (and even there are regular scandals of producers cheating).
The largest market of Chinese teas is not Europe, where there is a high awareness of environmental issues and the advantages of organically produced food, but in China itself, and neighboring countries where there still is little awareness of such issues. It will take time. Also in Europe it took time. When i was a child in the 1970's also in Europe very few people talked about things like "organic".
While these issues are beginning to be discussed in Asia, we are still quite far away from having the necessary regulations and enforcement, or even wide enough awareness in the society to issue such demands on the governments here. People here have more pressing issues - things that people in Europe take for granted nowadays are still luxury in many parts of Asia, such as free education, access to proper health care, etc. Nobody can blame people here if their priorities are somewhat different than in developed countries.
