So yes, this is yesterday Sonnentor Advent tea, which I just postponed because I didn’t wanted two caffeine-free teas and it just sounded as another herbal tea.
That said it is absolutely true it is another herbal tea. Nothing distinctive, mild, calming tea. Some sips were a bit bitter.
Too much acid in stomach? Maybe it can help, but why putting it in Advent Calendar? Maybe as a post-advent tea it would be better.
