Preheat the oven to 375°. Spray a large 9 x 13 x 2 inch baking pan with cooking spray.
Cut the bread into 1/2-inch cubes. Peel, core and slice the apples into 1-inch thick slices. Toss the apples with the apple cider vinegar.
If you want a deeper more yeasty and hoppy filling, you can soak the apple slices in 2 bottles of IPA beer for 2 hours at room temperature before making the brown betty. Just drain the beer, reserving 1/2 cup of it for the filling, and use the remaining beer for another recipe (like my rosemary cheese beer bread, my olive green onion beer bread or my pumpkin eclairs filled with chocolate beer pastry cream).
