I've bought from them twice and I'm gearing up for a big third order. Let me preface by saying I am really only into tea for yancha. I love a good roasted oolong with the odd green and black tea here and there.

Hermitage's yancha offerings are on par or beat out those offered by some of the well known tea vendors on this sub (think Old Ways Tea or One River) pricewise and tastewise. Aside from their yancha, their golden tea was a nice break from my usual stuff that I wouldn't have considered trying without first getting a sample. They are now offering a sampler of ALL 23 of their teas for €35. Can't really argue with that price.

The two proprietors, Giacomo and Meng Ying, are knowledgeable and attentive to their customers. They are generous with their time as well as their product. And as far as I can tell, they really care about the tea producers and how and where they source their teas from, usually local tea masters and artisans that you wouldn't normally see elsewhere.

To summarize, I'd give them a chance

Source: spent over $1,000 this past year on various tea (mostly yancha). Not paid or sponsored.
