O.N.E. Coconut Water HK$24 for 330ml, Nature's Village
Made with young, green coconuts from the Philippines, this drink packs 60 calories per packet and 'super-hydrating electrolytes' - 670mg of potassium, 60mg of sodium and 25mg of magnesium. PepsiCo has a majority stake in O.N.E, a company started by two master's degree students in Brazil.Verdict: weak coconut taste; drinking water would be just as satisfying.
Chi Coconut Water HK$24 for 330ml, Just Green
Produced in Thailand and packed in Germany for a London company, this drink seems to contain the least nutrition of the three: 25 calories per pack, 210mg of potassium, 17mg of sodium and 12mg of magnesium. Verdict: the strongest natural taste of the three, but still can't beat fresh coconut water.
H2Coco Pure Coconut Water HK$16 for 330ml, City'super
This is made with Australian coconuts - with added ascorbic acid (vitamin C). For some reason, it seems even 100 per cent natural coconut water varies in nutritional composition: this contains 85 calories per pack, 735mg of potassium, 66mg of sodium and 40mg of magnesium. Verdict: also lacks natural coconut flavour; slighty sappy taste.
