The wine is poured smoothly and slowly into the decanter, leaving the sediment at the bottom of the bottle. This process, known as decanting, is commonly referred to as "bottle changing". Therefore, rich red wine needs to "bottle change", meticulous red wine needs to be cautious; light age red wine needs to "wake up", aged red wine needs to be cautious and prudent.

Expanded Information

Sweet wines and full-bodied white wines. They have a wake-up time that typically takes more than an hour, such as French and Hungarian noble rot wines and German and Canadian ice wines. Full-bodied white wines, which are found in essentially every wine region around the world, are what make wines so complex.

A decanter is a glass or crystal vessel that is often used to "change" and "wake up" the wine. In the case of aged red wines, the tannins and pigments will form deposits over the years, which can be unsightly and slightly bitter in the glass. Therefore, after opening the bottle, the wine should in principle be poured smoothly and slowly into the decanter.

For shallow-aged red wines, by injecting the open time of the decanter (including the flow process when injecting), the wine can be exposed to a large area of air (the decanter's space and openings are larger), thus accelerating the softening of tannins, the full release of the closed aroma. This process is known as Breathing.
