Christophe Happillon is a Maitre Ecallier, which is like a sommelier for seafood. Merroir is a similar concept to terroir, but applied to the ocean. Oysters feed on phytoplankton, which can affect the taste characteristics of bivalve. Each estuary has very different phytoplankton which leads to very different qualities.
