a cooked-cabbage, rubber-boot, or old rubber odour. It occurs in wines that are made from grapes in very hot regions. Often these grapes are harvested with low acidity and high pH. It has been nick-named the Fresno odour from its occurence in that region after Prohibition in the 1930's in America.
You don't want this in your wine. When the sulphur in old whites starts to break down, you get the smell of old tires or rubber gloves. You are likely thinking, "How can cat pee be good and rubber is bad?"
An odor similar to braked car tires on pavement.
