September is here, and KOI Thé Singapore is serving up a little something extra that’s bound to sweeten the month for bubble tea lovers. For those who can’t resist a cup of creamy milk tea or refreshing fruit tea, this promotion is well worth your attention. From 1 to 30 September 2025, KOI Thé Singapore is giving away free Coconut Jelly topping with every drink – and yes, it’s available at all outlets except Changi and Jewel Basement.
Now, if you’ve been a long-time fan of KOI, you’ll know that their toppings are more than just a sidekick. They’re what turn a simple tea into an indulgent treat. Coconut jelly, in particular, is light, chewy, and adds a tropical twist to any drink. Imagine sipping on a classic KOI milk tea with that little bite of sweetness – it elevates the drink completely. For regulars, this is the kind of upgrade that makes their usual order even more enjoyable, and for newcomers, it’s the perfect excuse to explore the menu and try out different combinations.
This offer is available exclusively to KOI members, and that’s where things get interesting. Becoming a KOI member is not only simple, but it also unlocks a range of perks that make each visit more rewarding. With a KOI Card, members can enjoy payment convenience, loyalty rewards, and special treats like this Coconut Jelly topping promotion. And don’t worry – getting started as a KOI member is as straightforward as it gets.
All that’s needed is to pick up a KOI Card at any outlet (except Changi Airport Terminal 3 and Jewel Changi outlets), download the “KOI Thé SG” app, and register the card. From there, payment can be made by simply presenting the card or flashing the QR code in the app. Even better, members can track redeemable rewards directly within the app. It’s an easy way to stay connected to ongoing promotions while ensuring they never miss out on special member benefits.
Why should people take advantage of this promotion?
-
A Little Extra Without the Cost
Coconut Jelly is usually an add-on that costs extra, but throughout September, it’s absolutely free. For those who regularly add toppings, this makes a noticeable difference over multiple visits. Think of it as KOI giving a little gift back to their loyal customers. -
Enhances the Drink Experience
One of the great things about KOI is the customisation options. Their drinks are delicious on their own, but the right topping can completely change the flavour and texture. Coconut Jelly adds that chewy bite with a subtle sweetness, pairing wonderfully with creamy teas, refreshing fruit blends, or even KOI’s signature golden bubble milk tea. -
Encourages Exploration of the Menu
With the topping included, it’s the ideal time to try out different drinks you may not normally consider. For instance, pairing Coconut Jelly with a Passion Fruit Green Tea or a Yakult Green Tea creates an interesting combination of tart and sweet. This promotion provides the perfect reason to experiment without worrying about extra costs. -
Membership Benefits Go Beyond This Promotion
Signing up as a KOI member doesn’t just unlock this September deal – it’s an entry into a whole series of perks. Members often get exclusive discounts, seasonal promotions, and first access to special menu items. If people visit KOI regularly, the membership pays off quickly. -
Convenience at the Counter
The KOI Card and app make transactions much smoother. Instead of fumbling with change or cards, members can simply scan and go. It also makes it easier to keep track of spending and rewards. For frequent customers, this small detail adds up to a more enjoyable experience every visit.
Where can this promotion be enjoyed?
The free Coconut Jelly topping can be redeemed at all KOI outlets across Singapore, with the exception of Changi Airport and Jewel Basement outlets. This means it’s widely available, whether someone’s craving KOI during a quick lunch break in town, after dinner with friends, or while strolling through a shopping mall. The accessibility makes it even more attractive – there’s always likely to be a KOI outlet nearby when the craving hits.
A treat for September
What makes promotions like these particularly appealing is how they add a bit of joy to everyday life. Bubble tea has become more than just a drink – it’s part of the lifestyle in Singapore. From students to office workers, KOI remains a go-to spot when people want to reward themselves or simply take a break. With a free topping on offer, there’s an extra incentive to stop by a KOI outlet this month.
For those who are not yet members, the promotion is also a nudge to join the KOI community. Becoming a member doesn’t just open the door to this freebie but ensures that they’ll continue to receive exclusive perks long after September ends. KOI has built its reputation on consistently delivering quality drinks, and their membership programme is a way of giving back to loyal customers.
So, whether someone is already a KOI enthusiast or just dipping their toes into the world of bubble tea, September is a brilliant time to enjoy more for less. Free Coconut Jelly may sound like a small treat, but when added to a KOI favourite, it creates an entirely new level of indulgence – all without spending an extra cent.
In short, if September needs a little pick-me-up, KOI Thé Singapore has the answer waiting in a chilled cup.
