In the Western wine blogosphere, there's a stir about prices, but unlike our reality, it's all because of low prices.

A bottle of wine "Trebbiano — Pinot Grigio" (Puglia I.G.T. category) in a supermarket in France for €0.54.
This amount includes VAT (€0.09) and excise tax (€0.031); thus, the price excluding taxes and the retailer's markup (if any) is €0.42 — only slightly more than the cost of the glass bottle itself and other components.
There are also logistics costs, etc.

This is, of course, not a systematic and permanent price, but rather a factor of overproduction.
The winery decided to cash in somehow rather than sit on the wine material any longer.
Such are the realities (this applies not only to Italy, by the way).
