The "Organic" or "Organic" certificate, for example from JAS (Japanese Agricultural Standard) is very advantageous because it means that the tea has not been produced using pesticides, herbicides or other synthetic products. For cheap tea (well below 10 € for 100g) and for teas that do not come from Japan, we recommend to buy only organic tea. It is different for tea of very high quality, especially that from Japan, where agricultural practices in general are of very high quality. As a result, in the best green tea segment, the organic label is less relevant. Our kinesiological tests confirm this in many ways. In addition, there may be a "misleading effect" with the organic label. Organic plants must provide a much higher effort to draw nutrients from the earth and combat external attacks. Therefore, if this kind of plants are harvested two or three times a year (this is the case in the mid-range segment, or even more in the entry-level range), the tea becomes really nutrient-poor and therefore objectively low quality although labeled organic. From this observation it appears very clearly that the best organic tea comes from a plant that is exploited only once a year in non-depleted soil. In the case of Bio, the second crop is distinctly worse than the first one (bland, without energy and low in nutrients). Practical tip: Be sure to buy only organic tea harvested once a year. Otherwise, whatever the price or the marketing on this product, it will be of inferior quality. In places like China, India, Nepal, Africa and many Asian countries, the cheap segment is unfortunately very often synonymous with overproduction and standardization. So the teas are not only polluted but also come from very poor soils.
