Since I like Indian cooking, but often make the curry mixtures not my taste, is with me "much turmeric" just the most basic, which is blended with various other Sonnentor products.
Quality and taste of Kurkumas is certainly excellent, as far as I can say as an ambitious amateur cook.
That the can is only "half full" ("due to production" according to the label) no "ecological madness" is for me the following note:
It can be assumed that the machines just can not handle more weight per "unit" and "loose, lightweight items" then just fully fill the container unit, and "heavy" then leave corresponding amount of unused space.
That filling and packaging equipment is not "just so changed" can be, you should stop and consider, and probably be glad that we do not have 43 Sonnentor packaging sizes ... and then 25% may be paid for the product, because the manufacturing process is expensive.
