Wilkendorf's is a fourth generation family-run tea house and is considered to be one of the best…read moretea houses in Germany. They have certainly spoiled me with regards to my tea; I have failed to find a tea shop with a selection nearly as good as theirs. They travel to India, China and Japan on a regular basis to choose their tea, which reflects itself in the quality of their assortment. Besides tea, they have a good selection of accessories; you can find anything from tea water thermometers to crockery. Highly recommended if you should ever visit Karlsruhe and like your tea. Very good Chinese and Japanese green teas, and Darjeelings. My favourite mixed tea is their 'Jubiläiumsmischung', the perfect breakfast tea.
