I fell in love with sumac after using it at a Persian restaurant. I had to ask what it was, and then I found that some of the international groceries in my area didn't carry it, so Amazon is the way to go. I tried Zamouri sumac first, which was amazing. I am trying to reduce my sodium intake, and its a good replacement for salt on popcorn as well as for its traditional uses on rice, etc. After finishing 4oz, I thought I'd look for a good deal in shakers and saw this. Sumac is sumac, right? This sumac is ok, but neither as tart nor as flavorful as Zamouri's, at least not the batch I got. I'll enjoy it, but do plan on getting my favorite next time.
