AUSTIN, TX, August 7, 2026 — Long gone are the days when ready-to-drink (RTD) cocktails were limited to cloyingly sweet margaritas or boring, watered-down hard seltzers.
Today’s younger consumers want chaotic, intense flavor profiles that mimic the candy they ate as kids.
Seizing on this trend, party punch brand BeatBox Beverages has unleashed its latest sensory experiment: Xtreme Sour Black Cherry.
The limited-run flavor officially landed on store shelves nationwide on August 1, following a massive, sweaty debut among festival-goers at Lollapalooza.
According to the announcement on partner Anheuser-Busch’s newsroom, this high-acid liquid starts with a jammy cherry taste before hitting you with a punch of intense sourness.
It is packed in the brand’s signature resealable eco-carton, making it incredibly easy to toss into a backpack or cooler without worrying about broken glass.

Justin Fenchel, CEO and Co-Founder of BeatBox, noted that the product was born out of direct conversations with their core fanbase. “This launch is all about pushing flavor further and creating a taste experience that’s impossible to ignore,” Fenchel stated.
It is a smart play, honestly. In a market flooded with identical-tasting vodka sodas, standing out requires leaning into polarizing, bold niches that get people talking on TikTok.
It is hard to believe this brand started as a simple MBA project at UT Austin back in 2011. Most people first saw them on Shark Tank back in 2014, where they landed a pivotal investment.

Since then, the growth trajectory has been borderline absurd. Let us look at the raw numbers:
- Massive Retail Footprint: BeatBox is now distributed across all 50 states at more than 140,000 retail locations.
- Explosive Revenues: The brand generated over $350 million in retail sales in 2025 across total U.S. multi-outlet plus convenience (MULC) channels.
- Industry Leader: According to data from Circana, this represents a massive growth rate of nearly 50% year-over-year, making it one of the fastest-growing RTD brands in the country.

The backing of Anheuser-Busch has certainly helped grease the wheels of their massive distribution machine.
While the beer giant keeps its focus on legacy brands like Michelob ULTRA and Bud Light, its distribution network has allowed insurgent brands like BeatBox to scale at a breakneck pace.
Xtreme Sour Black Cherry will be available nationwide while supplies last.

Just make sure your stomach can handle the acid before you buy a whole case.
