Ray,

Sadly, that book has not been written yet.

With a collection of books you can approach that, but it is hard if you stay in
English. Part of this is that there is a feeling by many that classical
ampelography is as much an art as it is science. This is not a universally held
belief, but I believe it is more common with English speakers, who generally
have a more empirical focus.

If ampelography were pure science, reliable dicotamous keys could be developed -
they haven't. Galet tried this, and published some. There have been other
attempts to develop computer keys using multivariate analysis. These have been
a little successful, but are difficult to use, and their reliability breaks down
without an experienced user.

Of course, the trend is to use genetic ampelography, which is more reliable, but
still not very accessable.

Sorry I can not be more helpful.
