Wine-improving techniques have been in play for more than 100 years, and I like what malolactic-fermentation does to my wine. But (yes, Michael) Chapoutier has employed bio-dynamic wine growing techniques for (at the very least) 15 years. I BELIEVE 10 years ago, there was a particular fungus wreaking havoc in the Rhone region. All of Chapuotier's neighbors' had lost up to 90% of their vines (of which NONE had employed bio-dynamics) while Chapoutier had lost 10% or less of his vines (and of all of those, he only lost vines that had butted up to neighboring vineyards). I guess my point is, we have improved many ways of what we do to grapes AFTER they are harvested....Why mess with how we grow them??? There are modern improvements, but why question picking grapes by lunar cycles, when we do plenty of things to wine(need I remind us all of the freaking "Wine Clip?"?!
