Hard Kombucha Seltzer Exists and It's Pretty Delicious

July 10, 2019

By Jesse Bussard, July 10, 2019

The exact age of kombucha is unknown—estimates date it anywhere from 200 to 2,000 years old. Hard seltzer, on the other hand, has been on the alcoholic beverage scene for exactly one hot minute. Despite these chronological differences, however, a boozy kombucha and sour beer brewery in southwest Montana has deemed the two fit for marriage. 

Dean’s Zesty Booch, located in the scenic, growing town of Bozeman, claims to be the world’s first producer of hard kombucha seltzer. Unlike many more largely available seltzers, Dean's is made with real organic fruit. Each serving contains 108 or fewer calories and clocks in at a very sessionable 4.5% alcohol. Considering that DZB is literally in my backyard, I was excited about being the first to review a unique release. Of the three flavors I sampled, including Pineapple-Mango and Ginger-Lemon, the Blueberry Mojito was my favorite.

Appearance and Aroma

The hard kombucha seltzers come in tall, slim, 12-ounce aluminum cans. The word “ZESTY” emblazons the label over a white background along with details on the chosen flavor. Unlike its lighter-colored sister flavors, Blueberry Mojito pours a dark, yet translucent ruby hue out of the can. It's most likely meant to be consumed straight from the can, but when poured the liquid’s foam dissipates quickly, leaving a still-looking drink in my glass. As I swirl the seltzer, the strong aroma of berries and mint with a hint of lime zest come through.

I didn't used to be on the hard seltzer train, but Dean’s Zesty Booch has changed my mind.”


Blueberry Mojito is big on berry flavor. This fruitiness then transitions into a minty herbal taste with a tinge of lime and a crisp, clean finish. Like regular hard seltzers, it’s extremely refreshing and invigorating with a pronounced effervescence. Where this seltzer stands out, though, is the addition of a kombucha tartness, which lends an extra kick that a sour beer or kombucha-drinker like myself might find appealing. Put more simply, this stuff is just plain poundable while also being a palate-pleaser.


I didn't used to be on the hard seltzer train, but Dean’s Zesty Booch has changed my mind. My only complaint? I just wish it were more widely available, but unfortunately it will remain limited to the Big Sky State for the time being. Summer road trip?
