Decanting Sancerre isn’t necessary. But a younger Sancerre is one of the few white wines that does benefit from decanting! Because Sancerre is so complex, decanting the wine and allowing the oxygenation process to begin actually brings out the subtler flavors and makes for a more complex wine. Just don’t decant it too long before serving or you’ll lose some of that fresh acidity. No more than 30 minutes before serving.
