When it comes to popular tea brands in Singapore, few names stand out quite like Koi Thé. Known for their consistent quality, smooth brews, and wide range of flavours, they have long been a favourite among tea lovers here. Their drinks have an almost cult-like following, with fans eagerly waiting to see what seasonal flavours or special editions they might release next. This time, there’s an exciting deal that makes it even easier to enjoy their beverages without stretching the wallet too much. From 16 August 2025 onward, fans of Koi Thé’s Buckwheat Series can enjoy 10% off, but only when ordering via GrabFood.
Now, if you are someone who hasn’t yet tried their Buckwheat Series, this promotion is the perfect excuse to give it a go. The Buckwheat Series is not just another range of bubble tea; it is one of the healthier options in Koi Thé’s line-up, appealing to those who want something flavourful yet lighter. Buckwheat itself has been praised for its nutty, roasted profile, and when paired with tea, it delivers a warm, comforting, and slightly earthy taste that is refreshingly different from the usual sweetened milk teas.
Why this deal is worth trying
Promotions like these are not just about saving money, though the 10% discount is definitely a nice perk. It’s also about giving people a reason to try something new or indulge in a favourite drink a little more often. For regular fans of the Buckwheat Series, that small saving adds up if they’re ordering frequently. For new customers, it lowers the barrier to trying something they may not have otherwise considered.
Ordering on GrabFood also means convenience. Instead of queuing at an outlet during peak hours, customers can have their favourite Koi Thé drinks delivered straight to their doorsteps. This is especially useful on busy workdays or lazy weekends when heading out might not be on the agenda. Promotions that tie into delivery platforms like GrabFood make indulgence more accessible and appealing.
A healthier indulgence
One of the reasons this particular deal stands out is the fact that the Buckwheat Series is often seen as a healthier choice compared to sugar-heavy milk teas or fruit teas. Buckwheat is naturally caffeine-free, and when combined into drinks, it brings a roasted, tea-like flavour that is both soothing and unique. For people who might be cutting back on sugar or caffeine but still crave a tasty beverage, these drinks are an excellent compromise.
Additionally, buckwheat is associated with health benefits such as being rich in fibre, containing antioxidants, and supporting digestion. While it’s important to note that Koi Thé’s drinks are made for enjoyment and not marketed as health supplements, it doesn’t hurt that this range leans towards the lighter side. This makes the promotion appealing to both health-conscious individuals and those simply curious about different tea options.
Why Koi Thé promotions are always a big deal
Koi Thé rarely disappoints with their promotions. They tend to create deals that genuinely benefit their customers rather than offering something insignificant. This 10% discount might sound modest at first glance, but considering the premium reputation and consistent quality of Koi Thé drinks, it’s a worthwhile saving. Loyal fans know that Koi Thé drinks are priced fairly, reflecting the quality of the ingredients and craftsmanship, so even a small discount makes the deal much more attractive.
On top of that, the exclusivity of this promotion being on GrabFood makes it more exciting. It gives customers the feeling that they are getting a special, app-only deal rather than a standard in-store discount. It also incentivises people who may not use GrabFood often to consider trying it for the convenience and added perks.
Perfect for gatherings and sharing
Another aspect that makes this promotion appealing is how it suits group orders. Imagine having friends over or planning a casual family gathering. With GrabFood, you can order a variety of drinks from Koi Thé, including options from the Buckwheat Series at a discounted price. That small saving across multiple drinks can make a noticeable difference in the total bill, allowing more people to enjoy premium tea drinks without overspending.
A chance to explore different flavours
The Buckwheat Series isn’t just one drink; it often comes in several variations, such as buckwheat tea, milk tea versions, or even iced and hot options. This promotion is a great opportunity to explore the range without feeling guilty about the cost. For adventurous drinkers, it’s the right time to mix up the usual order and discover something new.
If someone usually sticks to the classic milk tea or golden oolong, this promotion might encourage them to try the roasted nuttiness of buckwheat instead. It’s these little pushes from promotions that expand people’s tastes and make their tea-drinking experience more exciting.
Why you shouldn’t miss this
In Singapore, deals like these don’t stick around forever. While the promotion starts on 16 August 2025 and continues “onward,” it’s clearly while stocks last. That means if the demand shoots up—and with Koi Thé’s popularity, it almost certainly will—there’s no guarantee how long the promotion will be active. Those who want to make the most of the 10% discount should act early rather than waiting weeks to try it.
Furthermore, it’s not every day that one of Singapore’s leading tea chains offers deals tied to healthier beverage options. It’s common to see discounts on milk teas or seasonal flavours, but the Buckwheat Series promotion feels unique in the sense that it promotes mindful indulgence.
Final thoughts
Koi Thé continues to impress with how they keep customers engaged through special promotions like these. By pairing their Buckwheat Series with a 10% discount on GrabFood, they’re making premium tea drinks more accessible and encouraging people to explore healthier choices.
For those who already love the roasted and nutty charm of buckwheat tea, this is an easy chance to save while indulging more often. For those who have yet to try it, this deal lowers the risk and cost, giving them the perfect opportunity to discover why so many fans swear by it.
With convenience, flavour, and savings rolled into one, this is definitely a promotion worth checking out. So the next time the craving for a comforting cup of tea strikes, why not take advantage of this deal and have a Buckwheat Series drink delivered right to the doorstep?
