Europe produces around 60-65% of the world's wine. That's a lot of bottles of wine. Last year, Europe produced more than 20 billion bottles of wine. While France continues to dominate wine production, its share has decreased noticeably – from around 40% to around 30% of European production over the past century. Italy's share has been more stable, at around 25-30%. 

Both countries are producing less wine than in their 1970s heyday, unlike Spain, which has a reputation for producing high-end wines at a lower price point than France and Italy, in part explaining its popularity. While Italy, Spain, and Portugal exported around half or more than half of their production, most countries kept their bottles in the local market. Romania, for example, exported a mere 5% of its wine last year.
