Susana Balbo Late Harvest Malbec 2016 - fiche technique
Susana Balbo is an icon of the Argentinian wine industry, she has been working in the trade for over 30 years and finally founded her own winery, Dominio del Plata, in 1999. Today it is a family affair with her winemaker son, Joseph, and daughter, Ana, working on the business side of the business. The winery, with its modern technology and equipment, in combination with precision viticulture and sustainable agriculture produces very high quality wines. Each grape variety is harvested manually and vinified to show the full varietal expression but with unique and individual styles.
The sweetness in the Susana Balbo Late Harvest Malbec is produced, as the name suggests, by leaving the grapes on the vine for as long as possible so they can become very ripe indeed. The almost-arid climate and altitude (1000m) of the vineyards in Alto Agrelo, Lujan de Coyu, Mendoza mean that fungal infestations are very seldom a problem. At harvest, the late harvest Malbec grapes are very ripe and raisined, they are hand-harvested, destemmed, gently crushed and then fermented in stainless steel tanks. The fermenting wine undergoes daily pumping over as well as delestages (racks-and-returns) three times a day. The wine is left on the skins for 35 days and undergoes malolactic fermentation. Finally the wine is aged for 18 months in 100% new French oak barrels.
Residual sugar is 60.5 g/litre - ie sweet, but lightly and not cloyingly so.
Dark ruby coloured, it offers a complex bouquet of cloves, cinnamon, tobacco and black cherries. On the palate, layers of ripe red fruits are combined with notes of dark chocolate and slight anise, leading to an amazingly long finish.
ABV = 11.5%.
