                                According to typical ready-to-drink protein shake manufacturing processes, the products are shelf-stable until opened due to aseptic packaging. However, the question remains: do Quest protein shakes need to be refrigerated, and what are the specific rules for storing them properly? The answer depends entirely on whether the bottle has been opened or not.
