I had been thinking about, in which I could fill Gewürzdose the powder - but this question has quickly superfluous. The so-called "aroma bags", in which the vanilla powder is, and closes perfectly airtight (better even than my protein bags!).
And most important, the taste is "fresh" and "pleasant" - just vanilla and no synthetic flavor, which can be harmful to health. Only the "real" brings many positive attributes with it.
Since I could not notice any drawbacks: 5/5 stars - buy recommendation!
