Global Warming: Italy Heading For Much Earlier Harvest

Due to a warmer winter and a scorching hot summer, many Italian winemakers may have to skip the annual summer vacation in August this year. Harvest will be earliest in the last 30 years with the Italian Wine Union declaring that the production will be slightly lower and the quality will be good but it will be remembered as the year of pest attacks.

Vincenzo Pepe, enologist at Lungarotti in Torgiano, Umbria is not optimistic about the possibilities of recuperation and re-equilibrating of the vegetal-productive period for a year that has been decidedly precocious.

"We are ahead of schedule by at least 3 weeks, and this could have been worse if rains and relative cool temperatures in the second half of June had not helped us,' he says.

"Precocious varieties like Chardonnay may see the harvest beginning around 10-15 August, given that we have had to change all of our company holiday plans, he adds".

Lorenzo Landi,enologist of Saiagricola , (Colpetrone, La Poverina, Fattoria del Cerro) consultant for many Italian winemakers noted: "we are ahead of schedule, on average of about two weeks, but it is necessary to make a distinction. Some areas have not been affected by the heat; I think Etna and Vulture, for example."

But for Carlo Ferrini, acclaimed Italian consultant in Italy , it is too soon to tell exactly when the harvest will be, though, "in Tuscany this year the harvest will definitely be in August; and in respect to the usual, operations will begin in the third week instead of the fourth. I think winery workers should get ready to revise their holiday plans.

One of Italy's most important winemakers, Riccardo Cotarella emphasizes that it is important to be prudent and remember that it is still difficult to tell. "The quality is determined from today onward and there has been certain recuperation, thanks to the good day-night temperature variations in recent days. There are some extra problems that could be calculated in the first forecasts, like in some southern regions like Calabria, Puglia and Sicily that were 'burned' by winds arriving from Libya".

Luigi Molo, enology professor at the University of Napoli Federico II, thinks there will be an average anticipation of about 15 days in Campania , with a few more difficulties for the coast compared to inland areas. "We'll see however, what will happen in July and August", adds the professor.

'The situation is very variable based on regional specific characteristics in terms of geographic aspects and laws and regulations,' says Lucio Matricardi, a winemaker and consultant for many wine projects, including the University of Milan and Chateau de Banyan of Bangalore, whom I had met at the Kumarakom Lake Resort, near Kochi last week for tasting of the just-launched Big Banyan wines under his nose.

'Where irrigation is not allowed the hot weather would create problems. So the Tuscan winemaker who can't irrigate may say that his Sangiovese would be more concentrated and the wine more expensive in 2007. Truth is Sangiovese cannot stand this dry and hot clime. It would not reach a good phenolic ripening level. There may be higher alcohol level of 14-15°C this year and the colour will also be more cooked', he says.

'Risk for white varietal is that skins will be softer. Phenols risk being released during winemaking process, making wine bitter, harsh and rustic. Whether the picking is by hand or machine, pressing is softer and more gentle compared to earlier years, temperature of grapes at the time of harvest etc. are some of the factors which will make a difference in quality' feels Lucio.

Whether the effect of weather is due to global warming or cyclical rotation of weather patterns is hard to tell but, 'Quality of this vintage will be variable, but not due to global warming alone. Today we have viticulture and winemaking tools to subdue the impact of clime but it will be a big challenge', concludes this Master Winemaker who did his Ph.D at the University of California, Davies.

In the Langhe region, a vintner is optimistic. "It is true that we are ahead by about 10-15 days, in fact the first Dolcetto grape berries are already starting to mature. But there was a bit of cool weather which helps with the perfect balance for vegetative processes".

The harvest of early ripening varieties like Chardonnay, Pinot Grigio, and Primitivo then, is expected to be in early August which will also see the grapes normally harvested in September, like Sangiovese, Merlot, Barbera and Trebbiano. The late ripening varieties like Aglianico, Raboso, Cabernet and Nebbiolo which normally see through September on the vine will be cultivated in September only.
