(TDB) - While interest in wine among younger consumers appears to be at an all-time high, and brands are being forced to wake up to the importance of engaging with the next generation of drinkers who will ultimately go on to shape the market, consumption in countries with a rich wine tradition like Italy, France and Germany is in decline and forecast to fall further over the next four years.

While Italy overtook France to become the world’s largest wine producer last year, at the same time domestic consumption fell to an all-time low. It’s a very different story in the US, which retained its crown last year as the world’s largest consumer of wine, with consumption slated to rise a further 2% between now and 2019 to 4.2 billion bottles per year.

Interestingly, millennial consumers are driving this growth, despite being increasingly lured to other drinks categories like craft beer and Bourbon, which seem more adept at speaking their language. Encouragingly, wine lovers in the US are adopting a ‘less is better’ philosophy, with sales of wine over $10 a bottle on the rise.

But while Americans may be forking out more on wine in general, boxed wine brand Franzia remains the world’s bestselling wine brand with a staggering 0.8% share of the total global market, according to Euromonitor. Consumption in China is picking up, with the country making an increasing impact on the global wine market. While exports are on the rise, imports grew by 37% in 2015 as the country’s thirst for wnes from all over the world develops.

Back home in the UK, Prosecco continues to dominate the headlines and sales, as the Italian sparkler is increasingly viewed as an everyday treat. But while the UK remains a key player on the global wine stage, it is not yet known how its decision to leave the European Union will affect trade.

With the powerhouses of the US and China dominating the global wine game last year, it’s unsurprising that the majority of brands in our top 10 hail from these two nations. But we’re keeping a close eye on Chile’s Concha y Toro, which is quietly but steadily rising to the top of the table with wines that outperform for their price points.
