the normal flavor progression is:
*START,, sweet with massive fruity aroma, bright color
*gravity below 1.020 most of the sweet is gone, some aroma gone and the wine is carbonated .. bitter flavors start to dominate
*gravity below ,, 1.000 sweet is gone, fruity aroma decreased and a yeast taste/smell dominates, bitter flavor from CO
2 dominates the mouth
*a month after racking ,, 90% plus of yeast has settled and bitter carbonation notes decreasing, fruity aroma is easier to pick out but significantly weaker than raw juice, We rack again
*six months after racking ,, the wine is mostly clear, yeast taste/ smell is gone, carbonation is reduced or not detected, fruity aroma can be emphasized by adding a bit of sugar
*bottle ,, sugar and acid were balanced and are pleasing, fruity aroma ranges from weak to strong depending on process, yeast flavors gone, if air exposure is excessive it is developing a burn note in the back of the throat
*well aged or high temperature storage ,, color is turning brown, becoming hard to identify fruit aroma
and they taste a bit rotten, nothing crazy but like a strong hint, this smell developes with in like 2 days of the fermenting beginning and thats the taste i end up with after fermenting, does this rotten taste / smell convert to something better and go away with aging?
rotten? as unusual fruity note,, you had poor quality fruit at the start or a mold infection
rotten? as egg ,, frequently a stressed yeast from a high temperature fast fermentation or lack of nutrients for healthy yeast
