Masi Amarone della Valpolicella Classico Costasera
By January the grapes weigh 35-40% less and have a naturally enhanced flavour and a higher concentration of sugar. Just the Corvina is attacked by botrytis ("noble rot").
After a delicate pressing and partial destalking of the grapes, they ferment for about 50 days in large Slavonian oak barrels at low, natural temperatures (natural cold fermentation).
The wine is racked off its lees, and transferred into barrels of 30-40 hl where the alcoholic fermentation continues for a further 3-4 months, encouraged by selected "Saccaromices Bayanus” yeasts. In the meantime malolactic fermentation also takes place.
Once the wine is completely dry, it is again rached off its lees and then continues its aging for another 20 to 30 months, partly in large oak barrels and partly in small Allier and Slavonian oak barrels of 600 litres (maximum 3 years old).
The wine is then filtered, bottled and aged in bottle for an additional 6 months or more before release.
