Why should wine be decanted before drinking?

Decanting wine is usually done to separate the wine from the brittle, bitter sediment that has formed at the bottom of the bottle due to aging, commonly known as "rebottle". At the same time, decanting can also allow the wine to come into contact with the air. After the wine "breathes", the tannins are fully oxidized, the surface odors and odors evaporate and dissipate, the floral and fruity aroma of the wine itself gradually comes out, and the taste becomes more complex and mellow. and suppleness.

Not all wines need to be decanted before drinking. Young, firm, full-bodied wines with heavy tannins need to be decanted. These wines are more expensive because of their bulky structure and ability to age. In addition, wines that have been matured for more than five years also need to be decanted because sediment may form. Those lighter-bodied wines do not need to be decanted. For example, most white wines can be drunk immediately after opening the bottle. Generally speaking, rosé wine, champagne and other sparkling wines do not need to be decanted.
