Michele Chiarlo 2020 Chiarlo Tortoniano BaroloAbout This Wine Tortoniano is named for the tortonian era (9 million years ago) soils in which the vines are planted, rich in microelements such as magnesium and manganese. Grape clusters are thinned and harvested up to 15 days later than usual for the fruit to attain a higher concentration. Temperatures are strictly controlled during vinification and the wine is aged for two years in large oak casks and one year in bottle before release.
