Drought: the vine does not suffer
Spring 2011 is the warmest spring (+2.6 ° C) since the beginning of the twentieth century, surpassing 2007 (+2.1 ° C) and 2003 (+1.8 ° C). The lack of rainfall between March and May 2011 (deficit of 55%) is also the largest before 1976 (46%) and 1997 (40%).
Result: the vine is ahead. Flowering, key moment, arrived three weeks early. According to the adage, the harvest takes place one hundred days later, the Beaujolais expects to harvest around 15 August, the Bordeaux and Burgundy in late August.
First question: the heat and drought are they harmful to the vine? In principle, no. The vine is a perennial plant with long roots, sometimes over 10 m, which are immune to the vagaries of weather: it is only the first foot of land that are dry.Only the vines suffer not worked and amended with very shallow roots.
We therefore takes a great vintage? Is going a bit far, because spring is not only the result. Moreover, in recent vintages hot, 2007 has not left a great memory, because the summer was wet and ruined the great hopes of the Champagne, Bordeaux and Burgundy, among others. Everywhere, 2007 are to drink, and only Sauternes and some great Rhone wines, especially side Chateauneuf-du-Pape, save the reputation of the vintage.
As for the 2003 vintage, with its very short growing season, it remains a curiosity, because with the hot clouds an average but the wines are of low acidity. At birth, the great Bordeaux had raised the enthusiasm of a few tasters, especially overseas, and prices had skyrocketed.But today, the big bottles are rare, first quantitatively, because the harvest was reduced, and they do not shine by their qualities. Those who blindly follow the sirens Bordeaux were fooled. It goes back to 1893 or to 1811 for a hot high quality, but primarily because the weather was dry.
Lower yield
Drought, it should not be confused with heat, produces other effects personal loans for bad credit. The concentration is generally at the rendezvous, but with diminishing returns. The year 1976, which is included in the collective unconscious with his "drought tax" does not figure in the pantheon of great vintages, came too late because the rain has swelled the grapes. In contrast, small droughts have resulted in some recent vintages, like 2005 and 2009.But not too much should not, because it can harden the wines, as in 2010.
For now, the drought of 2011 is not worrying at all, and the vine does not suffer. All the more she has spread the bloom in some places, which is still not a good sign for the quality of the vintage. If it lasts for another month or two, the vine will slow its growth and lead to smaller bays, resulting in a lower yield.
However, "until there is no rain, no need to treat, philosopher producer. The vines are planted on soils with good moisture capacity, which saves them. "Because, contrary to conventional wisdom, it is not enough sun and heat to make great wines, and even wine while short, seeing as Australian producers, who had been seduced by the warm valleys they are forced to abandon due to lack of water.Even with irrigation, there are no great wines in the deserts.
In the New World, the science of irrigation, source of many theses and a large number of studies, has made tremendous progress, but not enough to work miracles. Good wine, let alone the great wines, the result of a complex alchemy between the sun, temperature and water from the sky just as we must, with consummate skill and suspense.
