Wine flavors and aromas

[girlperson1]

I had read somewhere on the Internet that during the fermentation process, esters are produced which account for the various flavors and aromas that we preceive in wine. Different species of yeast will yield different esters.

These esters are "interpreted" by our brain. There really isn't chocolate in wine, but an ester can be present which will give the wine a chocolate aroma, the very same ester that will give chocolate it's own aroma as well. Yeast can be your friend!!
