You definitely shouldn’t be allowed to hide it like that, no. Unfortunately, they can (Dutch source).

The nutritional information does however state that there’s sugar. Even though the ingredient list does not.

Added sugar, that is. A lot of tea bags contain ‘aroma’, according to the ingredient list. However, this ‘aroma’ can be 60-70% sugar.

I can’t really find a source for it, but I remember the EU banning plastic in tea bags quite recently, a few years ago at most. Here in the Netherlands, a lot of tea bags contain(ed) plastic as some kind of sealant.

Also, a lot of tea contains sugar, for no good reason whatsoever.

There’s a big difference between European brands though.

French and Italian cars, for example, are generally not that reliable. However, BMW’s (German) are known to be quite reliable. Same goes for Volvo.
