We have seen in a previous article the importance for a winemaker to harvest, especially in the production of quality red wines, grapes that have a optimal polyphenolic maturity<\/strong>, evaluating the peel and pips very well.<\/p>\n

But why can even 24 hours be important?<\/strong><\/p>\n

At the biochemical level, many synthesis and polymerization reactions take place which from day to day allow us to have small but important changes.<\/p>\n

 <\/p>\n

What does polyphenolic ripening depend on?<\/h3>\n

Why are red grapes harvested when average temperatures are lower?
\nWhy have we heard of thermal shock?<\/p>\n

Let's see if these are all important factors for the winemaker.<\/p>\n

I have tried to summarize all the factors that play a fundamental role in polyphenolic quality of our grapes<\/strong> and consequently of our wine<\/strong>.<\/p>\n

Depend on:<\/p>\n

\u2022 Correct mineral nutrition<\/em>
\n\u2022 Limited vegetative vigor<\/em>
\n\u2022 Grape weight of the low strain<\/em>
\n\u2022 Respect the leaf surface ratio of 1-1.5 m2 per kg of grapes<\/em>
\n\u2022 Terroir and obviously form of breeding<\/em>
\n\u2022 Average daily temperature close to 20 \u00b0 during the ripening process (ie the period from veraison to harvest)<\/em>
\n\u2022 Minimum day \/ night temperature difference of 8\/10 \u00b0 C or higher<\/em>
\n\u2022 Water stress<\/em><\/p>\n

Nature plays a fundamental role and the vintage of a wine is the daughter of many factors.<\/strong><\/p>\n

And we're only talking about polyphenols.<\/p>","protected":false},"excerpt":{"rendered":"
