Vin Santo


Vin Santo is a style of Italian dessert wine. Traditional in Tuscany, these wines are often made from white grape varieties such as Trebbiano and Malvasia, though Sangiovese may be used to produce a rosé style known as "Occhio di Pernice" or eye of the partridge. The wines may also be described as straw wines since they are often produced by drying the freshly harvested grapes on straw mats in a warm and well ventilated area of the house. Though technically a dessert wine, a Vin Santo can vary in sweetness levels from bone dry to extremely sweet. While the style is believed to have originated in Tuscany, examples of Vin Santo can be found throughout Italy and it is an authorised style of wine for several Denominazione di origine controllata and Indicazione geografica tipica.

Origins of the name

Although the style of making wine from dried grapes has been around almost as long as wine has been made, there are many theories on how the particular name Vin Santo or "holy wine" came to be associated with this style of wine in Italy. The most likely origin was the wine's historic use in the Catholic Mass, where sweet wine was often preferred. One of the earliest references to a "vinsanto" wine comes from the Renaissance era sales logs of Florentine wine merchants who widely marketed the strong, sweet wine in Rome and elsewhere. Eventually the term "vinsanto" became almost an umbrella name for this style of wine produced elsewhere in Italy. When the Greek island of Santorini came under rule of the Ottoman Empire, the ruling Turks encouraged the island's wine production of a sweet dessert wine made from dried grapes. Over the next few centuries, this wine became known as Vin Santo and was widely exported to Russia where it became a principal wine in the celebration of Mass for the Russian Orthodox Church.
Another claim is that when the island of Santorini was ruled by Venice, packages sent from the island were labelled “Santo” to denote their origin, while their contents were labelled "Vin"; thus the term “Vinsanto” was born.
Other, likely apocryphal, stories on the name's origin attribute its naming to the work of a 14th-century friar from the province of Siena who would use the leftover wine from Mass to cure the sick. The miraculous healing became associated with the santo or "holy" wine and the name "Vin Santo" was allegedly born. Another 15th-century story involves John Bessarion, a patriarch of the Greek Eastern Orthodox Church. According to legend, at the Ecumenical Council of Florence of 1439 a local Florentine wine called Vin Pretto was served. After trying the wine, Bessarion is said to have liked it and remarked that it was like Xanthos, alluding to the famous straw wine of Thrace,. The Florentine locals thought they heard the patriarch describe the wine as Santo and they accordingly started promoting the wine as a "holy wine". Another oft-cited theory for the name association is the tradition of starting fermentation around All Saint's Day and bottling the wine during Easter week.

Production methods

After the grapes destined for Vin Santo are harvested in September or October, they are laid out on straw mats, often under rafters or staircases. They are kept in warm, well ventilated rooms that allow the moisture in the grape to evaporate. This process of desiccation allows the sugars in the grape to be more concentrated. The longer the grapes are allowed to dry and desiccate, the higher the resulting residual sugar levels will be in the wine. Depending on the style of wine desired, the grapes may be crushed and the fermentation process started after a few weeks or not till late March. Producers may use a starter culture of yeast known as a madre that includes a small amount of finished Vin Santo from previous years production. It is believed that this older wine can help jump start the fermentation process and also add complexity to the wine.
After fermentation the grapes are then aged in small oak barrels. In many DOC regions, the wines are required to age for at least 3 years though it is not uncommon for producers to age their wines for 5 to 10 years. Traditionally the barrels were made of chestnut instead of oak, which contributed high amounts of wood tannins and was very porous which promoted excessive evaporation in the barrel. Under this same traditional style of winemaking, a large ullage or air space would emerge in the barrel and oxidation took place. This gave the wine its characteristic amber but also flavours and traits that may be characterised as wine faults. Towards the end of the 20th century, more producers began switching to oak barrels while maintaining the tradition of not topping up the barrels and filling in the ullage space. This angel's share still produces some level of oxidation, though not as severe as the style was historically made. Modern winemaking technique also calls for more temperature control and keeping the wine in rooms with a consistent temperature that promotes more fresh flavours in the wine and fewer faults.
Some producers will still use non-oak barrels, such as chestnut, juniper and cherry wood and may even blend batches of Vin Santo aged in different wood barrels together. This has the potential of giving the wines more layers of complexity in much the same way that vinegar producers in the Emilia-Romagna region use different wood types to add complexity to their vinegar. As a fall back, if their wines become too oxidised or do not develop the way the producer wishes, some Vin Santo may be intentionally converted into vinegar that is very desirable in the culinary market.

Wine styles

The styles, colour, sweetness and quality of Vin Santo can vary widely depending on the grape varieties and production methods used to make the wine. While white grapes, such as Trebbiano and Malvasia in Tuscany, are most widely used, red grape varieties can be used to produce a rosé style wine. When red grape varieties are used, the wine is often labelled as Occhio di Pernice, which has its own DOC classification in several regions of Italy. The wines can be made to fit any style of sweetness levels from bone dry, almost Fino Sherry-like, to extremely sweet and on par with the botrytised wines of France and Germany. The wines can even be fortified with grape spirit added during fermentation, like Port. These fortified examples are usually labelled as Vin Santo Liquoroso.
The colour of wine Vin Santo can range from a pale to dark amber to even neon orange. The flavours typical of Vin Santo often include nutty or raisin notes with honey and cream attributes. In Italy it is traditionally served with biscotti that may be dunked into the wine.

Wine regions

For most of the 20th century, Vin Santo was often sold as basic vino da tavola due to Italian wine authorities' difficulties in classifying the many different styles of the wine. Today most of the major Italian wine producing regions have their own DOCs for specific Vin Santo wines produced in those areas. While the style is traditionally associated with Tuscany, examples can be found on the international wine market from throughout Italy. In the Trentino region, a dried straw wine made from the Nosiola grape is popularly labelled as Vino Santo. A noticeable difference between the Trentino and Tuscan examples is that the Trentino wines are usually less oxidised due to the wines regularly being "topped up" to prevent a large ullage.

Tuscan DOCs

Partial list of Tuscan DOC regions that are permitted to produce a Vin Santo style wine.
There are two main DOC regions that cover the production of Vin Santo in the Chianti zone. The Vin Santo del Chianti DOC overlaps with the entire Chianti zone and includes nearly every style and sweetness level of Vin Santo produced in Tuscany. Most of the Vin Santo that is sold on the international wine market is produced under this DOC designation. As with red Chianti wine, several village are permitted to add their names on the wine label as sub-zones. These sub-zones are Rufina, Montalbano, Colli-Fiorentini, Colline-Pisani, Colli-Aretini, Colli-Senesi and Montespertoli. White Vin Santo must have a minimum 16% alcohol level and is composed of at least a 70% blend of Trebbiano and Malvasia with other local white grape varieties permitted to make up the remaining 30%. The Occhio di Pernice style must have a minimum alcohol level of 17% and is composed of 50-100% Sangiovese with other local white or red grape varieties permitted to make up to 50% of the remaining amount. The wines are to be aged a minimum of 3 years prior to release with wines aged for at least 4 years eligible to be labelled as Riserva styles.
The Colli dell'Etruria Centrale DOC is located within the geographical boundaries of the Chiant zones this DOC is a "catch-all" designations for alternative styles of wines that would otherwise not qualify for anything above vino da tavola. There are three distinct styles of Vin Santo that can produced under the Colli dell'Etruria Centrale DOC label-Occhio di Pernice, Abboccato and Amabile. The first style, Occhio di Pernice, is a pale rosé style wine made from at least 50% Sangiovese with a mix of local red and white grape varieties permitted to fill in the remaining 50%. The wine must have a minimum alcohol level of at least 10.5% and be aged for at least 3 years prior to release. The Amabile and Abboccato styles related to their sweetness level with Abbocato designating a slightly sweet style and Amabile designating a wine that is sweeter but not quite as sweet as something that would be labelled as Dolce. These wines must have a minimum alcohol level of 15% and be aged for at least 3 years prior to release. If a Vin Santo is aged for 4 years, it qualifies to be labelled as Riserva wine. Both the Amabile and Abboccato wines must be composed of at least a 70% blend of Trebbiano and Malvasia with local grape varieties permitted to fill in the remaining 30%.

in Marche, includes 19 comuni within the region but only 2 are allowed to produce Vin Santo. The wine must have a minimal alcohol content of 12% and be aged for at least 3 and half years prior to release. The wine must be composed of at least 85% of Passerina with the remaining 15% coming from local white grape varieties.
Trentino DOC is a large province wide DOC covering the entire province of Trentino. The Vino Santo sub-zone covers the Valle dei Laghi area, using 100% Nosiola grapes air-dried for up to 6 months when they become affected by noble rot. Vinification takes up to 3 years to reach 12-13% abv. Most producers age the wine for 7-10 years but the minimum is 3 years. Vino Santo is one the most prestigious dessert wines in Italy.
