(NYPost) -Sacré bleu!

As many as 4 million bottles of cheap Spanish wine have been sneakily disguised as more superior French rosé, a sobering new report has found.

Up to 3.4 million liters of plonk was sold in bulk — and passed off as the real deal — with fake labels indicating the wine was “produced in France” and “bottled in France,” according to BBC News.

Shady producers also hid the true origin of boxed wine underneath packaging and beneath the handle.

The bogus blush was sussed out by investigators with France’s Directorate-General for Competition, Consumer Affairs and Fraud Control between 2016 and 2018.
