Good tea should be treated well. You need a good teapot, soft water and a little patience. The tea leaves, which have been carefully picked, unfold to release their aroma into the water, which shouldn't be too hot. The leaves need space. So they don't belong in a tea bag, a tea pincer of even worse a tea infuser. Tea needs to swim. It was von Grolman who in 1982 designed the world-renowed Mono Classic, the teapot of choice in the finer tea circles.
The rounded shape gives all the leaver the change to bond with the water. The lage rounded strainer offers them plenty of room. That is not possible in a tea infuser, is it? The tea creates a vacuum so it does not impact much flavour.
Mono offers a classic teapot for the QL lottery.
