You can now taste some proper plonk at a popup wine bar called The Vinery.
Did you know that “plonk” is really Cockney Rhyming Slang? The rhyme is PLINKETY PLONK, which rhymes with vin Blanc. It also echoes the sound of wine pouring into a glass. Very clever.
It’s one of those Cockney slangs that you probably use without even knowing it’s Cockney Rhyming Slang.
