The article says that yeast and drosophila are symbionts. The yeast makes all the eatery smells to attract the flies which then disperse it around the vineyard.
I had wondered why the yeasts put out so many different esters but now it's pretty obvious. The way we try to limit it is to minimize the amount of ammonium / amino acids (DAP, YAN etc) in the wort but as mutant yeasts don't emit esters, then surely it is only a matter of time before large distillers use GM yeast which give a purer alcohol and turbo manufacturers as well.
