Wine and Variables

[Thomas]

If I understand your question, you believe there is a recipe for making good wine, and there is.

Good wine is produced from good grapes, which rely on a good year and good growing practices in the vineyard. You cannot produce good wine from inferior grapes.

Of course, good can also be a subjective matter, but not to those of us who spend our lives earning a living from wine. And those who would make wine from a recipe are cooks not winemakers.
