Burmese grape
Baccaurea ramiflora · Phyllanthaceae · also known as Mafai, Lotka, Leteku, Rambai (loosely)
Not a grape at all but a trunk-fruiting relative of rambai — clusters of pink-to-crimson berries whose translucent white segments taste sweet-sour like a mild mangosteen. A monsoon treat from Assam to the Mekong, rarely seen beyond it.

The Burmese grape earns its trade name by looking the part in clusters, but it's a Phyllanthaceae — a close cousin of rambai and the otaheite gooseberry, not a vine grape at all.
When it's in season, by region
| Region | Peak months |
|---|---|
| South Asia | Jun–Aug (Assam, Bengal) with the monsoon |
| Southeast Asia | May–Jul (Thailand, Laos) |
How to select & store
Picking a ripe one
Choose full clusters of plump berries with taut skin, colored deep pink to crimson (yellow-pink ones are sourer). A gentle give and a fresh, sweet smell mean ready; wrinkled or leaking fruit has turned.
Storing it
Two or three days at room temperature, up to a week refrigerated on the cluster. Sour surplus goes to wine, pickle, and preserves — much as its cousin rambai does.
Practical uses
🍽️ Culinary
- Eaten fresh — squeeze the segments from the thin skin, spit the seeds
- Sour types made into wine, vinegar, and pickle in Assam and the Mekong
- Juices and cooling drinks in the monsoon months
- Jams and stewed relishes from the tarter fruit
🌿 Health & traditional
- Bark, root, and fruit used in Ayurvedic and Southeast Asian folk medicine for skin and digestion
🎎 Cultural
- Leteku in Assam, mafai in Thailand, lotka in Bengal — a beloved seasonal fruit that changes name at every border
- Cauliflorous, fruiting in ropes from trunk and branches like its Baccaurea relatives
Eating burmese grape: what to know
What regular consumption looks like
Burmese grape is a nutritious everyday fruit, best enjoyed as part of a varied diet. Its pigments and polyphenols are antioxidants that population studies associate with heart health, though that reflects overall diet rather than any single fruit.
Sensible amounts
A typical fruit serving is roughly a handful, one medium fruit, or about 80 g, and two or more varied fruit servings a day is a sensible everyday pattern.
Evidence & conditions
As a whole fruit, Burmese grape contributes fibre, vitamins, and beneficial plant compounds, but it has not been shown to treat or prevent any specific condition — so it is best enjoyed as part of a healthy diet rather than as a remedy.

The Burmese grape keeps its promise only in silhouette: hung in ropes of pink-to-crimson berries, it looks convincingly grape-like, but split one open and the truth is tropical — translucent white segments clinging to flat seeds, sweet-sour and melting, closer to a mild mangosteen than to anything off a vine.
Rambai’s louder sibling
Botanically this is a Baccaurea, the same genus as rambai, and the family traits show: cauliflorous fruiting straight from trunk and old wood, thin skins you pinch and squeeze, a monsoon-timed glut that villages take personally. Where rambai stays gentle, the Burmese grape swings wider — the reddest fruit is honey-sweet, the palest is sharp enough for the wine barrel.
A fruit with a passport of names
Follow it across the map and it changes identity: leteku in Assam, lotka in Bengal, mafai in Thailand, mak fai in Laos. That linguistic trail marks how thoroughly local it is — grown in dooryards and forest edges, eaten fresh the week it’s picked, and almost never exported because the soft fruit won’t survive the trip.
Beyond the fresh handful
Sweet clusters are snacking fruit, pure and simple — pinch, squeeze, spit. The sour ones become the interesting stuff: rice-and-fruit wines in Assam and the Mekong, tangy pickles, cooling monsoon juices. If you like the eating rhythm of lanzones, this is the same pop-and-spit pleasure in a redder skin.
