Sea Grapes FAQs

Sea Grapes Information

What are sea grapes & where do you find it?

Sea Grapes are part of the broad seaweed family and are known scientifically as “Caulerpa lentillifera“. Other names for it include green caviar seaweed or Umibudo. This delicious seaweed is traditionally found in the waters of Okinawa (Japan) but it has since spread to other parts of the world where tropical temperatures are common. Due to advanced farming and dehydration technology we’re able to grow sea grapes year round and pack the green caviar with a shelf life of 12 months, making it possible to ship this delicacy directly to you to enjoy at home!

How do you prepare green caviar sea grapes?

We have a dedicated page showing you exactly how to prepare and eat sea grapes here. The short version: Umibudo is served uncooked. Take the dehydrated umibudo (sea grapes) out of their bag and refresh them in iced water for two to five minutes for the small green berries to firm. The longer you leave the seagrapes in the iced water the less salt it will have. Serve condiments separately and simply dip the sea grapes into condiments. If condiments or sauces are poured over the umibudo, they’ll will lose their popping texture.

You can create many varieties of dishes with these beautiful sea grapes.

How many sea grapes will I receive?

Each pack of sea grapes contains 3.5oz/100g dehydrated sea grapes –  you can not eat the sea grapes right of the pack in their dehydrated state, you’ll have to steep them in fresh water for a few minutes first. You’ll see them come back to life right in front of your eyes, increasing in size and weight five-fold!

In total, once ready to eat and soaked, you’ll have around 1 pound/500g of fresh sea grapes.

Please store the sea grapes in their original packaging or in a closed bag/jar in a dry and cool place, avoid direct sunlight. Room temperature is great for sea grapes as they’re a tropical seaweed that loves warm conditions.

Use before expiration date which is at least 6 months after purchase – the best before date is 12 months from production.

Our sea grapes are harvested on a regular basis, so be assured that you’re receiving the freshest seaweed.
