While not always a bad thing, an overly reductive wine can smell of a struck match

While not always a bad thing, an overly reductive wine can smell of a struck match

How:  When a winemaker limits the amount of oxygen a wine has exposure to, technically to preserve the fresh, fruit notes.

What to look for: In the presence of volatile sulphur compounds – mercaptans – there’ll be a whiff of rotten eggs (from hydrogen sulphide) rotten onion (disulphides) and canned corn or tomato sauce (dimethyl sulphides).  Also  a distinct aroma of rubber or a struck match.
