The re-known laboratory Sofia GmbH in Berlin analyses each batch of tea for residues of pesticides. Our teas are probed for 486 residues. The results of the analyses are printed on each package.
Over the years the measuring methods have been improved and instruments have become more precise and accurate. Today one can detect even traces of residues from the environment in organic teas. Take a look how much residues a First Flush in 1994 contained in comparison to a First Flush of 2010.
