dear Albert,
you're right, I try to avoid any technology that could mark the wines, but this doesn't mean that we work in the cellar or in the vineyards as nothing is happened in these last 30 years!
You know, both me and my father we are oenologue, and I personally studied in Italy and France with some very good researcher, particulary on the matter of the influence of the work in the vineyards with the health of the skins and the increase of the natural yeasts during the fermentation.
You see, technics or developments could be good or bad, it depends how you use them and for which purposes.
Now for example we know that natural yeasts need at the begin of the fermentation a lower temperature to multiplicate better, that's why we chill the juice after the press, or that a very soft press could be very good for the extraction of colour and aromas, that's why we have a very modern press who work very very slow, and permit us, if we want, to leave some stems in certain vintages.
These are only examples of how many years of study and research helped us to understand better the wine, and, if we want, to avoid any chemical, sometimes useless chemical products.
I hope I've been clear, let me know what do you think,
Ciao, Andrea
