On June 8, social media was inundated with hashtag #roséallday social media posts with the celebration of National Rosé Day. The popularity of Rosé, however, is not contained to just one day — more like all year, experts say. According to data from Chicago-based SPINS, wine sales (non-liquor store) are up 2.3 percent year-over-year with Rosé leading the category's growth, up 13.3 percent to reach a $704.9 million annual market.

Certain other wine types represent a greater dollar volume than Rosé, such as red wine (up 1.4 percent to $5.7 billion), white wine (up 0.5 percent to $4.2 billion), and sparkling wine (up 7.3 percent to $1 billion), but Rosé's got them all beat in terms of dollar gains with an additional $82.6 million in sales compared with the prior year.

As temperatures climb in summer months, so do Rosé sales. Based on SPINS data, the wine varietal’s sales ascended to a peak of $66.1 million in sales over just four weeks (mid-June to mid-July 2018) representing a 17.8 percent growth over the same period in the prior year.

"Rosé is said to be the oldest type of wine but has become more popular lately, thanks in part to a strong social media presence," said Irina Mazur, president of product intelligence at SPINS, in a statement. "Will Rosé's popularity continue? Only time will tell, and we are keeping a pulse on the alcohol market to discover the latest adult-beverage trends and where the market is heading."
