WINE An enological overview by Mike Diliberto
GRAPES INTO WINE
[Speaking about wine drinkers]“He does not have to know anything about the biochemistry of fermentation, any more than he needs to know the difference between an ohm and a watt in order to turn on a light. …The satisfaction to be had from wine increases greatly if one knows what it is, how and why one wine differs from another, the sequence of changes that take place as grapes become wine.”
- Philip M. Wagner
