Singaporeans love a good drink, especially when it comes with a little extra perk, and KOI Thé is certainly delivering just that this season. For those who appreciate a rich, creamy bubble tea or a refreshing cup of their signature milk teas, this latest KOI Thé promotion is one not to miss. From 1 October 2025 onward, KOI Thé is rolling out an exclusive treat for their members: a free upsize for Rice Milk Tea vouchers. This is a fantastic opportunity for both loyal KOI Thé enthusiasts and newcomers looking to explore their offerings.
What makes this promotion particularly appealing is its simplicity and accessibility. Any KOI Thé member can redeem the free upsize Rice Milk Tea voucher at nearly all KOI outlets across Singapore, with the exception of the Changi Airport Terminal 3 and Jewel Basement outlets. It’s a single voucher per member, so it’s perfect for an individual treat or a small indulgence without the hassle of complicated terms and conditions.
For those who haven’t yet joined KOI Thé’s membership programme, the process is straightforward and offers more than just this seasonal perk. Becoming a member not only opens the door to this free upsize but also provides ongoing access to exclusive rewards, promotions, and customised offers that are only available to registered members. For anyone who enjoys loyalty perks and being in the know about upcoming deals, KOI Thé’s membership system is a no-brainer.
Here’s how people can join KOI Thé’s membership and start enjoying these benefits:
Step 1: Purchase a KOI Card
To become a member, simply visit any KOI Thé outlet and purchase a KOI Card. These cards are available at all outlets except for Changi Airport Terminal 3 and Jewel Changi outlets. The KOI Card acts as a convenient, reloadable payment option that can also hold all rewards and vouchers.
Step 2: Register through the KOI Thé App
After acquiring the physical KOI Card, download the KOI Thé SG app. This app is the hub for all KOI Thé members and allows them to register their card, check rewards, and manage their balance seamlessly. Registration is quick and ensures that members can immediately access all the perks associated with their card.
Step 3: Payment and Redemption
When it comes time to enjoy a drink, members can either present their physical KOI Card or use the QR code under the “Balance” section in the app for payment. To redeem the free upsize Rice Milk Tea voucher, simply tap on the “Redeemable Rewards” section in the app to confirm the available vouchers. It’s a hassle-free system that avoids long queues and complicated redemption processes.
Why This Promotion is Worth It
There are a few key reasons why this KOI Thé promotion is a must-try. Firstly, the Rice Milk Tea itself is a fan favourite. Known for its smooth, creamy texture and perfectly balanced sweetness, it’s a drink that appeals to both long-time bubble tea enthusiasts and those just discovering the charm of milk teas. The opportunity to upsize it for free effectively doubles the enjoyment without doubling the cost, which is always a win for savvy shoppers.
Secondly, the promotion encourages trying something new for members who might usually stick to a standard order. An upsize can transform a regular treat into a full indulgence, ideal for sharing or enjoying over a longer period. It’s also a timely offer for the spooky season, adding a festive twist to the usual drink menu. With the Halloween season in full swing, indulging in a slightly bigger treat feels like a small celebration in itself.
For those considering joining KOI Thé for the first time, the value of membership extends beyond this single promotion. The KOI Thé SG app keeps members updated with exclusive offers, limited-time promotions, and special rewards. For a community of bubble tea lovers, being part of the KOI Thé membership programme can enhance the entire experience by ensuring they never miss out on deals or seasonal specials.
Additionally, the simplicity of the system makes it appealing for busy Singaporeans. There’s no need to carry cash or worry about forgetting a voucher. The app handles everything digitally, from payment to redemption, which means members can focus entirely on enjoying their drinks. The convenience factor, combined with the tangible benefit of a free upsize, creates a compelling reason to head down to KOI Thé sooner rather than later.
Beyond the individual reward, this promotion also encourages social sharing. Friends and colleagues can discuss their favourite flavours, and the upsize offers a perfect way to share a drink without any extra cost. It’s these little experiences—sampling new flavours, enjoying a larger drink, and sharing with others—that make the KOI Thé experience memorable.
The beauty of this promotion is that it’s flexible. Members can redeem the voucher at nearly every KOI outlet, making it easy to fit into any schedule or location. Whether stopping by during a lunch break, after work, or while meeting friends, the free upsize is always accessible.
Finally, this promotion reminds everyone that being part of a membership programme can yield immediate and enjoyable benefits. Sometimes loyalty programmes feel abstract or complicated, but KOI Thé keeps it tangible, simple, and rewarding. A free upsize on a beloved drink is a straightforward perk that makes membership feel worthwhile from day one.
In short, KOI Thé’s free upsize promotion for Rice Milk Tea vouchers is a brilliant seasonal treat that combines taste, convenience, and value. For anyone who enjoys milk tea—or is simply curious about why KOI Thé has such a loyal following—this is the perfect opportunity to indulge a little more without spending extra. With straightforward membership steps, app-based convenience, and the festive timing coinciding with the spooky season, it’s a promotion that makes sense for both long-time customers and newcomers alike.
So, whether they are a bubble tea aficionado or someone looking for a small, enjoyable treat during their day, KOI Thé’s promotion offers a chance to upgrade their usual drink effortlessly. Given the limited nature of the voucher per member and the broad accessibility across Singapore (excluding only the two airport outlets), it’s definitely a promotion worth planning for. Don’t miss the opportunity to enjoy a richer, more indulgent Rice Milk Tea experience this season with KOI Thé.
