If you want to get some real delicious tea, you should visit the Amrumer Teekontor. Well... and if you are too far away for a direct visit, you still can order tea from afar via the internet. Great collection and wonderful flavours from heir house and homemage mixes. I love those teas
If you don't believe me... have a look here Amrumer Teekontor and order some for tasting. It sure is worth it and not even that expansive.
