Weeper
This actually doesn’t describe wine drinkers who get sentimental when they drink certain bottles. Rather, this refers to a bottle of wine that’s weeping or slowly leaking wine from the cork due to a small space around it. This could be the result of a faulty cork or because the bottle wasn’t stored on its side to keep the cork damp and therefore it dried and shrunk. A weeping wine isn’t necessarily spoiled, just as a weeping drinker isn’t necessarily maudlin.
