Following on from a previous mention on the Vit D/Cod Liver Oil thread about my green tea tasting "fishy"lately. I found this interesting explanation.
From a site called Tea Crossing.
Does Your Green Tea Taste Fishy? Why & What to Do - Tea Crossing
Talks about Dimethyl sulfide (DMS). "Both seaweed and some forms of marine life contain dimethylsulfoniopropionate (DMSP). DMSP creates DMS when broken down by bacteria, creating the fishy smell. DMS is found in Japanese green tea as well".
