Vinyl Taste

[jpy15026]

After about an hour a Riesling that I was excited about tasting (Covey Run) started to have a taste that I could only describe as vinyl...
The first glass (~ 4oz.) tasted very good, but a bit sweet and a very short, almost no finish. The second (4-5 oz.) is where I started to get this strong vinyl taste that I did not detect in the first glass. I’m trying to compare different Rieslings to find the one I like best, this is the first one I have tried. Do Rieslings have this taste; is this something common in Rieslings? Any clue on what this may be? I really made a conscience effort to really taste that first glass and I am sure it wasn’t in there. Has anyone had a vinyl taste in a Riesling out there?
Thanks in advance,
JPY
