Sea Grapes
Also known as: Lato (Filipino name) · Ar-arosep (Ilocano name) · Green caviar (trade name) · Latok (Malaysian name)
Definition
Sea grapes (Caulerpa lentillifera), called lato or ar-arosep in the Philippines, is a species of green seaweed from coastal regions of the Asia-Pacific consisting of upright branches bearing glossy green beads. One of the favored edible Caulerpa species for its soft, succulent texture, it is traditionally eaten in Southeast Asian, Oceanian, and East Asian cuisines — and it was first commercially cultivated in the Philippines in the 1950s, decades ahead of other countries. Filipino kitchens serve it fresh as a salad of ocean-briny “caviar” with tomatoes, onions, and vinegar. (Wikipedia)

Examples and Analogies
- Ocean Caviar on a Branch: Each pearl bursts with salty juice between the teeth, a vegetarian stand-in for the luxury of fish roe at sari-sari-store prices.
- The Seaweed That Paved the Way: Philippine growers were farming sea grapes in the 1950s before most of Asia thought of seaweed as agriculture — the barangay fishpond’s quiet head start.
Usage Scenarios
1. Coastal Farming Plots
Families in seaweed-growing areas tend shallow sandy-bottom plots of lato, harvesting bunches for wet markets and restaurants.
2. Fresh Salad Preparation
A cook rinses lato briefly in clean seawater or brine, tosses it with sliced tomato, onion, and a vinegar-calamansi dressing, and serves it immediately as an appetizer.
Strategies
- Harvest in the cool morning and deliver the same day, since sea grapes lose their pop within hours of picking.
- Rotate harvest patches and keep water quality high, as the crop absorbs and reflects the cleanliness of its grow-out area.
Security and Safety Measures
- Source only from clean, tested coastal waters — as filter-feeding-like macroalgae, sea grapes can carry heavy metals and contamination from polluted bays.
- Never serve spoiled or slimy batches; fresh lato should be glossy and firm, and food-spoilage on wet produce is fast at tropical temperatures.
Historical Context
Coastal peoples around the Asia-Pacific have gathered sea grapes from wild beds for generations, but the Philippines holds the distinction of first cultivating Caulerpa lentillifera commercially in the 1950s, an innovation that later spread to Japan and across the region. As Filipino seaweed culture diversified from gathering to farming, lato remained the fresh-market star — sold heaped in basins at wet markets and championed by chefs as a native “superfood” salad.

Challenges and Controversies
Water Pollution Exposure
Because the crop is eaten raw, outbreaks of contamination are traced to coastal water quality, putting the burden of safety on farm siting and monitoring.
Habitat and Tenure Conflicts
Expanding sea grape and seaweed farms compete for shallow coastal space with mangrove restoration, fishing grounds, and foreshore tenure disputes.
