Four Peaks Brewing Co. Launches Sun Day Solar Seltzer

PHOENIX — Four Peaks Brewing Co., Arizona’s largest brewery, announced today the launch of Sun Day Solar Seltzer, a hard seltzer produced using clean, renewable energy from the Arizona sun. Packages featuring four flavors—Lime, Grapefruit, Tropical, and Prickly Pear—will begin hitting stores in Four Peaks’ distribution footprint this week.

“The Arizona sun kicks our ass so hard every summer, we figured it was time we got a little something back,” says Melissa Osborne, head innovation brewer at Four Peaks.

So last year, the Tempe-based brewery installed more than 500 solar panels on the roof of its 56,000-square-foot Wilson production facility, where a majority of its year-round beers are made.

“The panels can’t power everything we do at the brewery, but they’re still able to convert a huge chunk of the energy we use to clean, renewable sources. All of the energy we use to produce Sun Day comes from the Arizona sun,” Osborne says.

But solar energy isn’t the only thing that sets Sun Day apart. Unlike most hard seltzers, which are brewed with artificial flavoring, Sun Day’s fruit flavors (Lime, Grapefruit, Tropical, and Prickly Pear) come from real, all-natural fruit juices. The difference can be tasted as well as seen—Sun Day Lime, for instance, has a soft greenish hue, while Sun Day Prickly Pear is bright pink.

“This isn’t mass-produced, cookie-cutter seltzer,” says Osborne, who designed the recipe for all four Sun Day flavors. “It’s fresh, it’s bright, and it’s really flavorful.”

Sun Day is 4.0% ABV and 99 calories per can. It will be available in six-packs of the Lime flavor and in mixed 12-packs that contain all four varieties. Packages will be landing in stores throughout Four Peaks’ distribution footprint (which includes Arizona, California, Colorado, Hawaii, Nevada, New Mexico, Texas, and Utah) beginning this week.
