Corvara groceries?

We are looking at an airbnb for 8 days in Covara. But find no data on groceries. We travel with back packs and by bus/train, no car. All we need is items like yogurt, bread, cheese, wine, coffee, some vegies... it is an easy walk to the "center" of corvara we are told.
We occasionally eat out but always at small, non gourmet, places. Knowledge?
We could take a bus to go grocery shopping if necessary.
