Gong cha is marking its 20th anniversary with a month-long promotional push that peaks on Sept. 15, when the bubble tea chain gives away a limited-edition Birthday Boba Bottle free to any guest who orders its anniversary-exclusive Birthday Drink at participating U.S. locations — while supplies last. The chain operates nearly 2,200 stores across 32 international markets, giving the campaign significant reach for operators and franchisees watching LTO execution at scale.
The Birthday Drink
The limited-time Birthday Drink — available Sept. 6 through Sept. 15 only — layers mango foam over Strawberry Milk Tea and finishes with sprinkles. The accompanying Birthday Boba Bottle was produced in limited quantities with no planned restock after the anniversary window closes. Guests who miss the free Sept. 15 drop can purchase the bottle for $4.99 with any purchase, while supplies last. Scarcity mechanics like these have proven effective at driving same-day traffic spikes in the dispensed beverage segment, where customization and collectibles increasingly drive repeat visits.
The Sweepstakes
Gong cha is also running a party sweepstakes targeting consumers who turn 20 in 2026 — sharing a birth year with the brand. Three winners each receive a full store takeover at their nearest Gong cha location for up to 20 guests, a free drink for every attendee, birthday merchandise for the winner, and free Gong cha for a year. Winners are selected at random and announced Sept. 14 at 2 p.m. CT on Instagram. The promotion underscores how specialty beverage brands are leaning into experiential rewards alongside points-based loyalty to deepen consumer attachment — a trend c-store foodservice operators have noted as dispensed beverage programs compete more directly with QSR and café formats.
What Operators Should Watch
Jenn Leitner, Vice President of Brand & Marketing, The Americas for Gong cha, called the anniversary "a major milestone" and pointed to the combination of the Birthday Drink, the collectible bottle, and the sweepstakes as layered tactics designed to reward core fans while bringing in new trial. The brand's mobile app — available on iOS and Android — supports ahead-of-line ordering, beverage customization, and loyalty point accrual, keeping digital engagement central to the campaign.
For c-store retailers tracking the specialty tea and boba category, Gong cha's anniversary campaign illustrates how franchise beverage concepts are raising the bar on LTO complexity and collectible merchandise. With bubble tea expanding beyond mall and strip-center locations, convenience operators with made-to-order beverage programs face a more competitive dispensed-beverage landscape heading into fall.
