Sea grape
Coccoloba uvifera · Polygonaceae · also known as Uva de playa, Uva caleta, Baygrape
The fruit of the salt-tolerant tree that lines Caribbean and Gulf beaches — hanging clusters of green-to-purple grapes with a single big seed, thin sweet-tart flesh, and a jelly so beloved it defines Bahamian and Floridian summers.

The sea grape tree is a coastline engineer — its salt- and wind-tolerant roots hold beach dunes together, so many are legally protected, and picking the fruit for jelly is a beloved, sometimes bureaucratic, summer tradition.

How to select & store
Picking a ripe one
Choose clusters where the grapes have turned fully purple or reddish and give slightly — they ripen unevenly, so the sweetest are the darkest. Green fruit is astringent and best left for the tree or the jelly pot.
Storing it
A day or two once ripe — the thin-fleshed fruit softens fast. Traditionally the harvest is picked ripe-purple and turned into jelly or wine within a day; the seeds are large, so yields favor preserving.
Practical uses
🍽️ Culinary
- Sea grape jelly — the Bahamian and South Florida classic, prized for its rosy color and beach nostalgia
- Eaten fresh off the cluster, spitting the big seed
- Wine, vinegar, and cordials from the ripe fruit
- Occasionally stewed into sauces and syrups
🌿 Health & traditional
- Bark and roots used in Caribbean folk medicine; the fruit valued mainly as food
🎎 Cultural
- The tree is a coastal guardian — planted and protected for dune stabilization and shade on tropical beaches
- In Florida it's a protected native, and gathering the grapes for jelly is a cherished summer ritual
Eating sea grape: what to know
What regular consumption looks like
Sea 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, Sea 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.

Walk almost any Caribbean or Gulf beach and you’ll pass the tree without knowing it feeds you: broad, leathery, salt-blasted leaves and, in late summer, dangling clusters of grapes that ripen from green to deep purple. The sea grape is the beach’s own fruit — a coastline guardian that stabilizes dunes and, as a bonus, makes one of the region’s most nostalgic jellies.
A grape only in shape
Botanically it’s no relative of the wine grape — it’s in the buckwheat family — but the resemblance is close enough for the name to stick. Each fruit is thin-fleshed around an oversized seed, sweet-tart and lightly astringent, ripening unevenly along the cluster so the darkest grapes are the sweetest. Eaten fresh, it’s a spit-the-seed beach nibble in the same spirit as the Southern muscadine.
Jelly is the point
Because the flesh is thin and the seeds large, the sea grape’s true calling is the preserving pot. Sea grape jelly — rosy, tart-sweet, and faintly wild — is a Bahamian and South Florida institution, sold at roadside stands and made in home kitchens from grapes gathered the same morning. The ripe fruit also ferments into country wine and vinegar. The big seeds that frustrate fresh eating simply strain out.
Protected on the beach
The tree’s ecological job complicates the harvest in the nicest way: because sea grapes anchor dunes and shelter shorelines, they’re often protected — a Florida native you may need permission to prune, even as generations gather the fallen fruit for jelly. It’s a fruit inseparable from its place, tasting, unavoidably, of summer at the shore. For another tough, beautiful coastal-and-desert fruit, see the prickly pear.
