Etymology 2
From WWI military slang, derived by alteration of French vin blanc (“white wine”)[1] by the law of Hobson-Jobson. Recorded earliest in the playful rhyming slang form plinketty-plonk.[2] Possibly influenced by the sound of wine being poured into a glass.
Noun
plonk (uncountable)
- (uncountable, UK, Ireland, Commonwealth, informal) Cheap or inferior everyday wine.
1998, Pierre Spahni, Swiss Wine Market Report, page 95:The third category of wines is highly unattractive as these may only be sold as generic wines (white, red or rosé), without reference to any geographical location. Only surplus plonk and cooking wine would aspire to fall in this segment, which can be blended with any other wine - to any extent.
2003, Joan del Monte, Plonk Goes the Weasel, page 201:Diesel took a large swallow out of the glass of red wine. He spluttered, choked, and spilled wine down one leg of his fawn colored pants. “My God,” he gasped, when he could speak. “What is that crap?”
“Why cheap red wine,” Ford displayed the label. “You know. Plonk.”

- Given the results reported in this chapter, one obvious solution to the ‘plonk paradox’ (why cheap wine tastes good on holiday but terrible at home) would be to try and recapture some of these sensory impressions in one′s own living room, in order to enhance the flavour/pleasantness of the wine-drinking experience (and turn that horrible tasting wine into something that tastes really rather nice), and to elucidate the respective contributions of contextual effects on hedonic ratings.
