There is something completely off about the flavor. We usually purchase this exact item from Costco, and have compared the two bags side-by-side. We could tell immediately after opening this bag that the smell was off, and after mixing it with water like usual, the flavor was also different and unappetizing. We received the shipment in December 2020, and the expiration date is May 2021, which seems too soon. It might be that this brand has a shorter shelf life than they claim. I would stick to ordering this from another source.
