To detect a corcked wine ? Nothing more simple! It is enough to get back the cork of the bottle that you have just uncorked and just smell the part which was in touch with the wine.
If the latter smells slightly the cork, then the bottle is probably corcked. You can also serve the wine in a glass and smell it, or even taste it, because these methods also allow to locate the presence of cork.
Why a bottle is corked ?
The cork of corks come from barks of tree. If the tree in question is affected by this disease, it also affected the cork, as well as the bottle in which it is.
