signs indicating a bottle of wine has been heat damaged.
- extreme acidity.
- tastes too alcoholic due to lack of other flavors (one dimensional).
- sometimes tastes bitter or sour.
- sometimes has a granular consistency (usually with older wines).
- swelled or cracked cork (often misshaped after removal).
after a trip out of the country i returned home to find that a bottle of wine had been heat damaged while in our apartment. you should be able to see the cork damage from the photo. =(
