Great Eastern Sun has joined forces with a new Japanese-Chinese company cultivating Certified Organic Nori (Porphyra yezoensis) in the coastal waters off China to bring you better taste and higher quality at a lower cost with the guarantee of purity that only Organic Certification can bring. The Japanese partner is a long-established nori producer with more than 100 years experience growing and processing nori. Emerald Cove® Organic Toasted Sushi Nori is cultivated from certified organic nori spores gathered from the previous year's crop. The young plants are nurtured in protected aquatic beds free from pollutants until they are strong enough to be transferred to nets in shallow ocean waters. They never treat these nets with herbicides, pesticides, or fungicides, but instead remove invading pests by hand.
