How to tell if a wine is faulty, has "turned", or may be undrinkable (oxidized or too old)?
- Off Color. Red wines will be faded. White wines will be darker than they should be.
- Cork Position. The cork has pushed out too far.
- Off Odor. Examples: moldy, wet cardboard, rotten eggs, burned, band-aid or antiseptic smell.
- Off Taste. Examples: astringent, vinegar, or unpleasant chemical.
