How to pick a ripe Green Coconut

How to pick

Pick the heaviest nut for its size and give it a gentle shake — a clear sloshing sound and real heft mean it is full of sweet water (a light, hollow-sounding nut has lost water or dried out). On a whole green coconut, look for a uniform green husk with a creamy-white top cap; gray skin means it is old, and avoid cracks or wet, moldy eyes. On a trimmed white 'diamond-cut' coconut, the cone should be clean uniform white with no pink, gray or brown tinge and the wrap dry and intact — any surface discoloration or mold around the eyes means it is going off. Both heft and the shake test are fine to do in-store; never try to cut or pierce it on the shelf.

Red flags

• A light nut with weak or no slosh — it has lost its water or dried out
• Gray husk on a whole nut, or pink/gray/brown discoloration on a trimmed white one — past its prime
• Fuzzy black, orange, or pink mold around the eyes or cut surfaces
• Cracks in the shell, or a sour, fermented smell — the water has spoiled
• Condensation and softening under the wrap on trimmed coconuts — accelerated spoilage

How to store

A whole green coconut keeps best refrigerated at about 37–43 °F (3–6 °C) and, thanks to the insulating husk, can hold for roughly 2–3 weeks — don't freeze it, and avoid the very coldest spot, which browns the skin and can sour the water. A trimmed or cellophane-wrapped white coconut is far more perishable: refrigerate and drink it within a few days to about a week. Once opened, drink the water promptly; exposed coconut water sours within a day or two even chilled.
