Or at least, tell me if there's an "established" name for it.
I was at a free tasting tonight, and one of the selections was Green & Red California Zinfandel. I wasn't really impressed, though it was a decent enough wine until the finish, when something put me off. In the finish, just after swallowing, I could detected something that I tried to explain to the gentleman pouring the wine, and I more or less said "at the risk of sounding like a complete savage, I'd describe the finish as "seafood"". He gave me a strange look, and took a sip, and then agreed! Yet he didn't know how to describe it either.
Basically though, it had a very discernable note of not quite fishyness, but more like the aroma of sea scallops or seaweed even. Maybe "seaweed" is the word I'm looking for?
Anyway, I thought I'd share. The tasting was worth going to despite this weird experience, however, as I was able to grab a case of 1996 Ch. Meyney at the store for $16.80 a bottle :)
