Mid-Autumn Festival is often associated with mooncakes, family gatherings and the simple pleasure of sharing something sweet with the people who matter. This year, Rive Gauche is giving the traditional celebration a more contemporary dessert twist with its Seasonal Lunar Box, featuring a pair of beautifully crafted mousse cakes inspired by refreshing tea, citrus and tropical fruit flavours.

From 25 August to 11 September 2026, dessert lovers can enjoy 15% off the Seasonal Lunar Box from Rive Gauche, both in stores and online. For those planning to bring something different to a Mid-Autumn gathering, this seasonal offer could be worth a closer look.

The promotion also comes with an online discount code, RGMIDAUTUMN, making it easier for shoppers who prefer to place their orders online. However, there is an important date to remember: collection for the Seasonal Lunar Box begins from 28 August 2026.

A Modern Take On Mid-Autumn Desserts

Traditional Mid-Autumn celebrations have plenty of familiar flavours, but Rive Gauche is taking a different route with its seasonal mousse cakes. Rather than going for a conventional mooncake-style dessert, the Seasonal Lunar Box focuses on light, delicate flavours and layered textures.

The box brings together two mousse cake creations: Jasmine Tea Clementine and Passion Peach Exotic Fruit.

The Jasmine Tea Clementine option combines fragrant jasmine tea with bright clementine. The pairing offers a balance between the gentle floral character of jasmine tea and the lively citrus notes of clementine. It is the sort of flavour combination that may appeal to anyone who prefers desserts that are refreshing rather than overly rich.

The second creation, Passion Peach Exotic Fruit, takes a fruitier direction. It pairs luscious peach with vibrant passion fruit and tropical notes, giving the dessert a more colourful and refreshing profile.

Having two different flavours in the same seasonal box also makes it a convenient choice for sharing. Instead of having to choose just one dessert, there is an opportunity for family members or friends to try both and decide which flavour is their favourite.

Enjoy 15% Off During The Promotion Period

The main attraction of this Rive Gauche offer is straightforward: shoppers can enjoy 15% off the Seasonal Lunar Box from 25 August to 11 September 2026.

The discount is available through both Rive Gauche stores and its online channel. For online orders, shoppers can use the promotional code RGMIDAUTUMN when placing their order.

This is particularly useful for people who already have Mid-Autumn gatherings planned and are looking for a dessert to add to the table. Ordering online can also be a more convenient option for those who want to arrange their purchase ahead of time rather than making a last-minute trip to a store.

At the same time, those who prefer to browse in person can take advantage of the same 15% discount in stores.

It is worth remembering that the promotional period begins on 25 August, while collection starts from 28 August. This means shoppers should check the relevant collection arrangements when placing their order, especially if the dessert is intended for a particular gathering.

Why This Deal Is Worth Checking Out

There are plenty of reasons to consider this promotion, particularly if the usual Mid-Autumn treats are starting to feel a little predictable.

First, the Seasonal Lunar Box offers something that feels different from the traditional festive dessert selection. The combination of jasmine tea, clementine, peach and passion fruit gives the box a modern character while still fitting naturally into the idea of celebrating together.

Secondly, the two-flavour format makes it suitable for sharing. Mid-Autumn Festival is, after all, a time when people come together, and a dessert that can be divided among family or friends can make a gathering feel that little bit more special.

The 15% discount is another reason to take a look. Seasonal creations are usually available for a limited time, so a discount during the launch period gives dessert fans a chance to try the festive collection while paying less than the usual price.

It could also be a practical option for anyone looking for something to bring when visiting relatives, meeting friends or hosting a small get-together. A nicely presented seasonal dessert can work as a sharing treat without requiring much preparation.

A Dessert For Those Who Like Lighter Flavours

One of the more interesting aspects of this collection is the emphasis on flavour combinations rather than simply sweetness.

Jasmine tea and clementine create a pairing that sounds particularly appealing for those who enjoy floral and citrus notes. Meanwhile, the Passion Peach Exotic Fruit option brings together peach and passion fruit with tropical flavours for something more vibrant.

That variety means the box can cater to different preferences around the table. Someone who enjoys tea-inspired desserts can try the Jasmine Tea Clementine, while fruit lovers may naturally gravitate towards Passion Peach Exotic Fruit.

For Singapore’s warm weather, refreshing fruit-led desserts can also be especially tempting. A mousse cake with citrus and tropical fruit notes can make an appealing alternative to heavier desserts after a festive meal.

Planning A Mid-Autumn Gathering?

If there is already a family dinner or gathering in the calendar, this promotion is worth keeping in mind before the festive period gets busier.

The promotion runs until 11 September 2026, giving shoppers some time to plan. However, the Seasonal Lunar Box is a limited seasonal creation, and collection only begins from 28 August, so anyone hoping to enjoy it for a particular occasion should plan ahead.

The online option also means shoppers can arrange their order without necessarily having to make a special trip to a store. For those who prefer shopping physically, the offer is also available in Rive Gauche stores during the promotion period.

Before ordering, it is sensible to check the available collection details and any applicable terms directly with Rive Gauche, particularly if the box is needed for a specific date.

A Festive Treat With A Contemporary Twist

The Mid-Autumn Festival does not always have to be about sticking to the same flavours and traditions every year. Part of the fun is discovering new ways to enjoy the occasion, especially when sharing food with family and friends.

Rive Gauche’s Seasonal Lunar Box takes that idea and turns it into a modern mousse cake experience. With Jasmine Tea Clementine and Passion Peach Exotic Fruit in the box, there is a good mix of floral, citrus and tropical flavours to explore.

The 15% off promotion from 25 August to 11 September 2026, together with the online code RGMIDAUTUMN, makes the seasonal collection even more tempting for those who are already considering a festive dessert.

For anyone in Singapore who enjoys trying limited-time desserts, wants something different for a Mid-Autumn gathering or simply likes the idea of sharing a beautifully presented sweet treat, this Rive Gauche promotion is certainly one to consider. The key is to remember that collection starts on 28 August 2026, so planning ahead could make it easier to enjoy the Seasonal Lunar Box at the right time.
