Slow-Cooked Beef Roast with Red Wine Sauce

I made this one down at Dads for my family (hubby, son, daughter, son-in-law, nephew - his wife and daughter, my sister and Dad and also sent some along with the other things I fixed to a neighbour who has been in the hospital and her husband). Everyone who eats beef loved it. Almost everyone peeked in the slow cooker while I was cooking and said this smells great and oh is that little whole mushrooms. They devoured it at supper. Hubby said it was the best roast he's every had.
