Are crystal glass decanters really worthy of all the hype? Different decanters are required for different spirits – some spirits do not specifically need decanting and can be decanted in any kind of decanter. In terms of appearance, these decanters are simpler and have a stopper to prevent the flattening of the spirits. To remove the sediments and soften the tannins, it is necessary to let some wines breathe. Among these, red wines, vintage ports, and some white wines require crystal glass decanter. Also, there is no need of stoppers in wine decanters.
