What is "plonk"?

Plonk is a derogatory and informal term used to describe wine that is considered to be of low quality and taste. It is typically used to refer to inexpensive wines that are mass-produced and lack any distinctive or complex flavors. Plonk is often associated with wines that are made from low-quality grapes, have been overproduced in large quantities, and have not been aged for a long time. These wines are often characterized by a lack of depth, balance, and complexity, and are generally not considered to be enjoyable to drink by wine enthusiasts. The term "plonk" is often used to convey a sense of disdain or contempt for the wine being referred to, and is sometimes used humorously to describe any wine that is perceived to be of low quality, regardless of its actual price or origin.
