Rainer Schmidt has acquired extensive knowledge about tea through travels to tea-growing regions as well as through trading, storing, and blending in the Speicherstadt. For the first time, over 150 tea varieties from around the world are explained and illustrated in such detail, including specific plantations and their size ratios. The growing regions are equipped with the most precise maps, and the harvest times for each region are presented in clear graphics. Many countries have centuries-old tea traditions and have even developed their own tea ceremonies. Furthermore, the correct purchase of tea, its storage, and the optimal preparation of all varieties are thoroughly described with abundant visual material. A comprehensive glossary explains all the terms related to the world of tea. Until 2006, he was established as a tea importer in the Speicherstadt, where he stored and traded tea.
