Incrocio Manzoni

Manzoni Bianco 6.0.13 Manzoni Bianco 6.0.13, also known as Incrocio Manzoni, is the most famous clone of Prof. Luigi Manzoni, principal of the Scuola Enologica di Conegliano (Conegliano School of Oenology), during a series of experiments conducted on the genetic improvement of the grape vine through crossings and hybridizations.
In Italy, work on the genetic improvement of the wine-producing grape varieties started around 1924. One of the pioneers was Prof. Luigi Manzoni, who set up a series of combinations in two different periods: the first series between 1924 and 1930 and the second series between 1930 and 1935, with the aim of creating a white grape cultivar and a red grape cultivar that could favourably replace the varieties that had been grown until then.

Once the crossing programme, involving the choice of the parental varieties, which are essential for obtaining good results, had been set up, the experimenters proceeded to execute the cross-breeding, which occurred in three stages:
1. Emasculation of the flowers of the seed-carrying variety, an operation carried out manually a few days before the start of the flowering, and covering of the bunches that were prepared.
2. Collection of the pollen of the cultivar chosen as the father.
3. Pollination was carried out when the stigmas of the flowers were receptive.

The resources available to Prof. Manzoni were not sufficient, either in terms of staff or in terms of surface available. He therefore created a vineyard with plants of various grape varieties but he was confronted with the problem of having to mark them.
In the first period, the crossings were marked with two numbers, the first indicating the row in which the plantling was positioned, the second relating to the position of the plantling within the row itself. The second series instead was marked by a group of three numbers, the central one of which is always “0”. This number was probably inserted simply to distinguish the series. The three numbers therefore indicate: the row, the series and the number of the vine in the row.
Incrocio Manzoni 6.0.13, in particular, was created during the second period of the experimentation, between 1930 and 1935 and was combined as follows: The flowers of the 13th plant of the 6th row, a Pinot Bianco, were inseminated with the pollen of the Riesling Renano grape variety.
The Professor thus obtained a new variety which had inherited the best of the French and German schools. Pinot Bianco guaranteed a magnificent structure and an excellent body, while Riesling contributed its fragrances and array of aromas. Manzoni Bianco 6.0.13 is able to adapt to very different climates and soils, although it prefers hilly areas, deep, fresh and fertile soils which are not too hard, and it offers a limited production. It has a small, conical- or cylinder-shaped bunch, often winged, and it is moderately compact (the weight varying between 80 and 150 grams). The berry is small-medium, round and yellow-green, the skin is thick, rather firm, generally covered with bloom and it has an aromatic flavour.
Incrocio Manzoni is a wine with a good body and a balance between the alcohol level, acidity and other elements it contains. It has a characteristic light straw colour.
Due to its finesse and elegance, good alcohol content and acidity, it is used to produce high quality wines. When vinified, the cultivar produces an fine-grained, elegant wine with a good body and superb balance..
