I find most countries which produce a range of a particular consumer food/beverage tend to export their lowest quality of that good in the largest quantities. Globally, it's relatively easy to find either Stella Artois, Heineken, Guinness, Corona, Fosters, Budweiser, Asahi, or Tsingtao wherever you go. They're not great. But each of their respective countries makes fantastic beer - they just drink it all domestically. Americans will say European beer is bad based on this, having never tasted proper Belgians. Europeans will say American cheese is shit, having never tasted Wisconsin's best cheeses. Because for the most part we don't export our best. Wine is a bit of a lemon market in the USA - there are some knowledgeable buyers but most buyers are laypeople who are faced with 200 options and no way to distinguish them other than price and country of origin. So if the only that that differentiates the wine at the time of purchase (not at the time of consumption), the optimal thing to do is to stock as much cheap wine as you can from each country but then price them all at different tiers. That way someone coming in for a $25 bottle of Spanish wine, finds a $25 bottle of Spanish wine to buy. Yes there are some discerning customers, but if you fail to cater to them you'll still sell a whole lot of wine to non-discerning customers.
