Malvasia Bianca Lunga belongs to the extensive Malvasia family and is generally believed to have originated in the eastern Mediterranean basin, with probable links to the Greek winemaking tradition. It has been cultivated in Italy for centuries, particularly in Tuscany, where it is also known as Malvasia del Chianti or Malvasia Toscana, and has played a part in the history of Chianti wines and Vin Santo. The leaf is medium-large to large, pentagonal and generally five-lobed, with a slightly blistered margin and a tomentose underside. The bunch is large, pyramidal, often compact and has two wings; the berries, which are small to medium in size, are spherical, with a pruinose skin, of medium firmness and green-yellow in colour. Its main growing area encompasses the Chianti hills, the Florentine and Sienese regions, the Valdarno and the Maremma, with the variety also found in Umbria, Lazio, Liguria, the Marche and certain areas of southern Italy. When vinified, it produces straw-yellow wines that are delicately aromatic, with subtle floral and fruity notes, accompanied by savouriness, smoothness, good alcohol content and a balanced structure. Its versatile nature is evident in both dry white wines and in wines made from dried grapes, where it contributes to complexity, depth and remarkable ageing potential. The most significant oenological curiosity is its traditional role in the production of Vin Santo, often in combination with Trebbiano Toscano.
