When you use a decanter, trying to avoid pouring the sediment into your glass means you may inadvertently leave some of the wine behind. Or, if you try to pour all the wine out, the sediment may escape into your glass. When you use Spirale wine glasses, there is no need to plan ahead to separate sediment from your wine, either via decanting or filtering. Plus, some bottles of wine may surprise you with sediment. Be spontaneous and avoid the work of cleaning a decanter! Simply open, pour and enjoy — Spirale wine glasses have you covered.
