NEVER BUY STEW MEAT. It's usually round steak (gluteus) which gets tough when you cook it unless you use meat tenderizer. Buy center blade chuck steaks and cut it up into large chunks as they shrink. CostCo has them. Safeway probably not. And why would you buy from meat counter that stinks?

Don't just toss everything into the instant pot. It doesn't brown which creates flavor. Brown the meat in the pot, then add the spices for a minute to let the "bloom". Water is fine but a dry red wine is so so much better.

At the very least buy the right meat and brown it. That will make all the difference.
