The former wine and spirits editor for Bon Appetite magazine recommends this little gadget, and that was enough to make me want to give it a try. It clips around the neck of your wine bottle, and the Neodymium magnets help to aerate the wine and break down the harsh tannins, resulting in a smoother and more-balanced wine. It’s enough to elevate a plonk to a pleasure.
