Origin
Different species of Porphyra can be found in all oceans.
Appearance
The leaves are appetisingly bright red, you can easily spot this algae in the sea and taste it fresh. Nori has very delicate leaves that grow up to two metres.
Production
Nori is traditionally grown on ropes in Asia. The young, thin leaves are harvested after only a few weeks in the sea. Eruopean products come from wild harvests.
