According to international expert reviews: Decanting is suitable for all red wines and can help the wine deliver a better flavor.
Decanting time varies according to grape variety, production area, age, storage time in barrels and differences in terroir. In Europe, the red wine is usually opened 1 hour before the meal to let the red wine decanted. Most studies show that in general, young wine of around 3-7 years and more than 80% of red wine will require a decanting time of around 45-60mins using a traditional glass decanter.
If you wish to enjoy a red wine with full-bodied aroma, a mellow taste, complex layers and a lingering after-taste, the effect of aeration will be more obvious if you select red wines from grape varieties or growing regions with “strong tannins”. For example:Grape varieties such as Cabernet Sauvignon, Cabernet Franc, Syrah, Petite Sirah, Nebbiolo, ontepulciano, Malbec, Tempranillo, Sangiovese, Sagrantino; and growing regions such as Bordeaux, Burgundy, Rhone Valley, Barolo, Barbaresco, Rioja, Jumilla, Napa and Chianti.
