> For reference, French wine in France can be had for 3 or 4 euros a 75 cl bottle.

This legend about french cheap wine is getting better and better everytime I hear it. 3-4€ is the low price for wine in a bottle. Some are decent, some are utter shit. But that's not "for good wine". That's entry level, which sometimes is decent.

I know some of the export wine is cooking-grade shit and people don't know the difference. But for people versed in wine in the US, the €3-4 bottles aren't going to cut it.

I don't know how it is in a WallMart in the US but in a French Carrefour there can be a 20 meter long aisle dedicated to wines and spirituous, possibly both sides of the aisle.

That's a huge selection covering all types of wine for as little as a few euros. Price is not a predictor of anything, there are both good and bad wines all over the place.

Wine is truly a commodity in France. There are very few people paying 10€ a bottle unless you're talking Champagne, that's not considered a wine.

I am french. I know the supermarkets, and still I frequently buy bottles above 10€. My demographic is not small, there are just many people that can't afford storage space for bottles and don't want to buy entry-level wine.
