History
[edit] Marchesi di Barolo 1952, first producer to label it as Barolo In addition to being a prominent figure in the Risorgimento, Count Cavour played a significant role in the development of modern-day Barolo Until recently it was believed that up to the mid-19th century, Barolo was a sweet wine. This was attributed to the fact that the nebbiolo grape ripens late in October, meaning that temperatures would be steadily dropping by harvest. By November and December, temperatures in the Piedmont region would be cold enough to halt fermentation, leaving a significant amount of residual sugar in the wine. Another popular idea was that in the mid-19th century, Camillo Benso, Conte di Cavour, the mayor of Grinzane Cavour, invited the French enologist Louis Oudart to the Barolo region to improve the winemaking techniques of the local producers. Using techniques focusing on improving the hygiene of the cellar, Oudart was able to ferment the nebbiolo must completely dry, making the first modern Barolo. This new, "dry" red wine soon became a favourite among the nobility of Turin and the ruling House of Savoy, giving rise to the popular description of Barolo as "the wine of kings, the king of wines". The idea that Barolo was once a sweet wine and that it took a French oenologist to turn it into a dry wine has been recently challenged, based on new research, by Kerin O'Keefe. According to this revision of Barolo's history, Paolo Francesco Staglieno was responsible for the modern dry version. He was the author of a winemaking manual, Istruzione intorno al miglior metodo di fare e conservare i vini in Piemonte, published in 1835. It was Staglieno who was called upon by Camillo Benso, Conte di Cavour, who appointed him to the position of oenologist at his Grinzane estate between 1836 and 1841. Staglieno's task was to produce quality wines geared towards ageing and stable enough to be exported. Staglieno fermented the wines dry, something that at the time was referred to as "the Staglieno method". Oudart was a grape and wine merchant, not an oenologist, who in the early 1800s moved to Genoa and set up a winery, Maison Oudard et Bruché. By the time Oudart turned up in Alba, King Carlo Alberto and Cavour were already following Staglieno's guidelines and both were producing dry wines. This revised version of the history of Barolo was positively accepted by other experts. By the mid-20th century, wine production in the Barolo zone was dominated by large negociants who purchased grapes and wines from across the zone and blended them into a house style. In the 1960s, individual proprietors began estate bottling and producing single vineyard wines from their holdings. By the 1980s, a wide range of single-vineyard bottlings was available, which led to a discussion among the region's producers about the prospect of developing a Cru classification for the area's vineyards. The cataloguing of Barolo's vineyards has a long history dating back to the work of Lorenzo Fantini in the late 19th century and Renato Ratti and Luigi Veronelli in the late 20th century, but as of 2009 there is still no official classification within the region. However, in 1980 the region as a whole was elevated to DOCG status. Along with Barbaresco and Brunello di Montalcino, Barolo was one of the first Italian wine regions to attain this designation. The Barolo wars[edit] In the 1970s and 1980s, trends in the worldwide market favoured fruitier, less tannic wines that could be consumed at a younger age. A group of Barolo producers, led by the house of Ceretto, Paolo Cordero di Montezemolo, Elio Altare, and Renato Ratti, started making more modern, international styles of Barolos by using shorter periods for maceration (days as opposed to weeks) and fermentation (usually 48–72 hours or at most 8–10 days), less time ageing in new small oak barrels and an extended period of bottle ageing prior to release. By using modern technology, including specialized tanks that allow the wine to be pumped out from underneath the cap of skins and then pumped over, they found ways to maximize colour extraction and minimize harsh tannins. Prior to this "modernist" movement, nebbiolo was often harvested slightly unripe and at high yields, which left the grapes with harsh green tannins that had not had time to fully polymerize. To maximize colour extraction, producers subjected the wine to extended periods of maceration, taking up to several weeks, and then several years of ageing in large oak casks to soften the wine. Through the long slow process of oxidation, the perception of tannins lessened (such as occurs when decanting wine), but the fruit would also fade and become oxidized. The decline in fruit would no longer be able to balance the remaining harsh tannins, leaving a bitter, astringent wine with withered fruit. To counter this change, some producers would blend in other grape varieties such as Arneis and Barbera to add colour, fruit or softness to the wine. The use of small French oak barrique barrels is a winemaking technique associated with "modernist" Barolo producers Advances in viticulture have helped to bridge the gap between modern and traditional producers. Better canopy management and yield control have led to riper grapes being harvested earlier with more developed tannins in the grape skins. As of 2015[update], winemaking for both traditionalist and modernist Barolo producers includes strict hygiene controls and the use of some modern winemaking equipment such as temperature-control fermentation vessels. Rather than fall into one hardline camp or the other, many producers take a middle-ground approach that utilizes some modernist techniques along with traditional winemaking. In general, the traditional approach to nebbiolo involves long maceration periods of 20 to 30 days and the use of older large botti-size barrels. The modern approach to nebbiolo utilizes shorter maceration periods of 7 to 10 days and cooler fermentation temperatures between 28–30 °C (82–86 °F) that preserve fruit flavours and aromas. Towards the end of the fermentation period, winemakers often heat the cellars to encourage the start of malolactic fermentation, which softens some of nebbiolo's harsh acidity. Modern winemakers tend to favour smaller barrels of new oak that need only a couple of years to soften the tannic grip of the wines. While new oak imparts notes of vanilla, it has the potential to cover up the characteristic rose notes of nebbiolo.
