If you’re someone who finds joy in discovering sweet little perks throughout the month, here’s a delightful one that might just make your August a lot more satisfying – especially if you’re a milk tea fan. KOI Thé, a brand beloved by bubble tea enthusiasts across Singapore, is rolling out an exclusive treat this August 2025. For a limited time, KOI members are entitled to a free upsize for their Red Bean Purple Rice Milk Tea, and honestly, it’s one of those things too good to miss.
Let’s unpack why this seemingly simple promotion is worth paying attention to – and why even those who aren’t yet members might want to jump on board.
Why KOI Thé’s August Promotion Deserves Attention
First off, KOI Thé is no stranger to creating beverages that strike a perfect balance between indulgent, refreshing, and satisfying. Their Red Bean Purple Rice Milk Tea is especially unique – a creamy, rich milk tea blended with chewy purple rice and subtly sweet red beans. It’s not your everyday bubble tea. It’s a dessert-like treat in a cup, offering not only flavour but texture and nourishment.
Now, imagine getting this satisfying beverage in a larger size without any additional cost. That’s exactly what this promotion is about.
This is not just about saving a few dollars – though that’s a welcome bonus, of course. It’s about enhancing the entire bubble tea experience. That extra volume means more sips of goodness, more enjoyment of the chewy grains, and more time to unwind with your favourite drink. It’s an offer that appeals both to the tastebuds and the wallet – a winning combination.
Exclusivity Adds Value
Let’s be honest – part of what makes any promotion feel special is its exclusivity. KOI Thé is offering this perk only to KOI members. That immediately adds an air of privilege to the deal. It’s a little ‘thank you’ from them to loyal patrons, which makes long-time fans feel appreciated. For those who haven’t yet joined, it presents a clear incentive.
Memberships are free to sign up for, so there’s essentially no downside. By signing up, one opens the door to future rewards, early access promotions, and other member-only privileges – not just this free upsize in August.
Furthermore, the promotion runs across almost all KOI Thé outlets, making it incredibly accessible – with the exception of the Changi and Jewel Basement outlets. So for most Singaporeans, it’s just a quick visit to their nearest branch.
Great for First-Timers and Regulars
If you’re already a KOI regular, then you probably don’t need much convincing. But if you’re someone who’s heard of KOI Thé but never tried it, this could be the ideal introduction. Their Red Bean Purple Rice Milk Tea is distinctive, combining the creamy satisfaction of milk tea with the wholesomeness of grains and legumes – almost reminiscent of a Taiwanese dessert.
That free upsize gives first-timers a little extra to enjoy, which is always appreciated when exploring new tastes. It also gives regular customers a reason to indulge again – perhaps even more frequently during the month.
Making the Most of the Deal
Here’s the catch – and it’s a minor one. The offer is limited to one voucher per member for the entire promotion period. That means no multiple redemptions, so you’ll want to make your visit count. Plan to enjoy it on a day when you’ve got time to savour it, perhaps with a friend or after a long day at work.
What makes the deal extra appealing is that there’s no purchase minimum, upselling, or fine print requiring you to buy other items. Simply walk in, present your voucher, and get that delicious upsize, hassle-free.
Beyond the Drink – The KOI Member Advantage
It’s worth noting that KOI Thé’s member system isn’t only useful for this August promotion. Members often get early access to new drinks, seasonal items, birthday perks, and even the occasional surprise discount. So if you’re someone who enjoys keeping up with what’s new and what’s next in the world of milk tea, it makes perfect sense to register.
The KOI card is digital, meaning it’s easy to sign up and manage via their app. With this, you’ll never miss an offer – and you’ll always have access to your loyalty perks right at your fingertips.
Perfect for August’s Mood
August in Singapore typically sits at that transitional space between summer vibes and pre-festive season calm. People are looking for little comforts – whether it’s a cold, creamy beverage during a humid day or a small treat to lift the workweek. KOI Thé’s Red Bean Purple Rice Milk Tea fits perfectly into this vibe.
It’s also a good way to treat oneself without spending too much. These moments of indulgence don’t need to be extravagant – sometimes, it’s just about stretching your dollar a little further, getting a bit more of what you love.
Don’t Miss Out – Make August a Little Sweeter
Free upsizes may sound like a simple gesture, but for those who enjoy milk tea – or those looking to try something comforting and unique – this is the kind of everyday luxury that brings joy without guilt. KOI Thé has earned their name in Singapore’s vibrant beverage scene by delivering quality and consistency, and this member promotion is another example of them rewarding loyalty in a meaningful way.
If you’ve been a KOI fan for years, take advantage of this offer to enjoy more of what you love. If you’re new to the scene, this is a great opportunity to see what the buzz is about – and to do so with a bit of extra value.
And if you aren’t a member yet? Signing up takes just a moment, and it opens the door to this month’s deal and many more down the road.
