Generally, these products are used more for reds than they are for white for a variety of reasons- but that doesn’t mean you can’t use them on your whites! Reds are typically served at room temperature, and stand to benefit a lot from being decanted and aerated. These devices are designed to be used at room temperature and are great at adding a little oxygen before hitting your glass. While they can be used on whites, users may run into some difficulties when it comes to storing it in the refrigerator to keep it cool. There is a little bit of debate whether these devices that run off of batteries can be stored in the refrigerator. We find it prudent to err on the side of caution, and perhaps invest in a vacuum sealer to keep whites cool and fresh without possibly damaging your device.
