Just because the red wine just taken out is bitter doesn't mean it must be fake wine, but it is probably not sober. Red wine needs to sober up first, otherwise it will be bitter.
The wine just taken out of the wine cabinet will produce a certain smell during storage because of insufficient oxidation and sediment of wine residue.
Before drinking, sober up with a sober-up device, ranging from half an hour to an hour. The better the wine, the more sober you need.
Sobering up is to make red wine fully contact with the air and accelerate the volatilization of odor.
