Luckily, my foil wrapped tea bag wasn’t cardboardy, so I assume it is an error of Nordqvist advent calendar.

Anyway, honestly it surprised me it is a black tea, because I haven’t paid enough attention to it. And it was very sweet when dry, when brewed… it was quite floral (as pears can be), quite creamy and vanilla for sure. The pear flavour itself, not the florality; isn’t much present. Which is a shame, as it could be much better, if that fruit flavour would be much more distinctive. Sadly, this way it is black tea with floral notes and creamy vanilla for me
