Plenio is Umani Ronchi's Verdicchio Riserva, a class recognised by the production rulebook, which prescribes a minimum ageing period of 18 months of which at least six must be in bottle. The name of the wine, from the Latin Plenum, is intended to suggest the characteristics of fullness, complexity and structure. It is a wine to be appreciated for its lingering persistence and for its richness of perfumes and aromas, which combine with the elegance of great whites to make it a unique wine. The first few years were produced from a plot in the Villa Bianchi vineyard, but now Plenio is the product of vines grown at higher altitude, in one of the areas historically regarded as more suitable for the production of Verdicchio, near the picturesque village of Cupramontana.
The vineyard was planted in the early 90s, and is situated at about 350 meters above sea level, with an east‐facing aspect. The soil, which derives from formations from the pleiocene‐pleistocene era, is characterised by being very deep clay loam, with fairly poor fertility and therefore extremely suitable for the production of quality wines. The yield is in the region of 6‐7 tons per hectare.
The harvest is carried out by hand, with the grapes collected and transported in boxes. Normally it takes place on the borderline between the first and second ten days in October, when the grapes have reached an optimum balance between acidity and sugar content.
After a soft pressing, the prime must is rapidly cooled and then goes through static decantation. Fermentation takes place a part (60%) in temperature‐controlled stainless steel tanks, and the rest (40%) in 5000 litre oak casks. About 10‐15% of the total volume of the wine undergoes a malolactic fermentation. The ageing stage lasts about 12 months, during which the wine remains in contact with its own fermentation yeasts. Plenio completes its ageing with a further 6 months in bottle.
Pale straw yellow in colour with golden hues. The bouquet is round, soft, fresh, with hints of vanilla and ripe fruits. On the palate, the wine is velvety, soft, rich and harmonious, with a characteristic hint of citrus rind on the finish.
This wine is suitable for vegetarians and vegans.
