THE CHOICE OF GRAPE VARIETIES AS A RESILIENCE BUILDING TOOL

Using climate models and historical records of wine grape ripening patterns, scientists have shown that roughly 50% of the planet’s current wine-growing areas won’t be climatically suitable for their present variety if temperatures increase by 2°C. Changes in climate are expected to impose new challenges to this long-term varietal selection.  Indeed, the climate changes are very likely to have key effects on wine quality and style, which over the long term may cause geographical shifts in suitable grapevine varieties and production areas. In another hand we been witnessed thar grapes have tended to be harvested roughly 2 weeks earlier than they had been previously. So, choose the correct long-term solution to cope with climate impacts is crucial. Wine growers can opt to plan ahead for climate change, but: Do we have enough knowledge about grapes varieties, and its clones to make a choice? Can also rootstocks be a part of solution? What data do we need to consider when making this decisions? Aren’t regulations to straight to select different varieties when producing certified wines?

THE DEBATE

In this Climate Talk we will explore the impacts of climate trends in vines and wines across the world, and which are the long-term solutions producers such consider adapting their vineyards. For this talk we count with producers from different parts of the world that are already leading the way regarding the research on the behavior of grapevines clones and studying the role of rootstocks as an adaptation measure to deal with climate impacts. We will explore the solution that are being tested and their results and reveal some of the directions pointed by latest researches.

THE TOPICS

 What changes are we already seeing on wine growing regions?
 Have winegrowers started to take steps towards the new climate projections?
 Can biological diversity in grapes help buffer against climate change?
 Despite the huge global varietal diversity (There are more than 6,000 known grape varieties grown in the world), the top 100 varieties represent an incredible 80% of all the grapes planted. Is this sustainable?
 Such we be looking for more adapted grape clones or rootstocks?

DAN PETROSKI. USA

Winemaker at Larkmead Vineyards

Dan Petroski was born and raised in Brooklyn, NY, and has the swagger and the accent to prove it. After attending Columbia University where he played football, Dan went to work for Time, Inc. While there, he earned his MBA from NYU and worked his way up the ranks towards a promising future in magazine publishing. A good chunk of his tenure at Time was spent managing advertising clients, which involved considerable schmoozing. This is how Dan learned wine, by walking his expense account through the lists of Manhattan’s top restaurants. When the Wall Street Journal tried to poach him, Dan took a moment to reflect. Deciding a change of life was in order, he jettisoned to Sicily for a year, where he interned at Valle dell’Acate. While Dan’s intention was to return to New York to sell wine, a harvest invitation from Andy Smith at DuMOL in 2006 was too good to pass up, and Dan left the city again, this time facing west.After harvest, Andy Smith hired Dan as Cellar Master at Larkmead. The following year, Dan was promoted to Assistant Winemaker, ultimately claiming the Larkmead Winemaker title in 2012. Before cementing his status as a Napa Valley Cabernet winemaker, in 2009 Dan launched a white wine only brand called Massican.  Massican is Dan’s ode to the Mediterranean and his time spent living in Italy and drinking white wine. Dan is a gifted, instinctual winemaker, and his old world palate has guided his philosophy on wine.  Dan’s approach and ability to craft wines as diverse as Cabernet Sauvignon and Tocai Friulano has earned him the recognition as San Francisco Chronicle’s Winemaker of the Year in 2017.

After completing his schooling in Portugal and England, David spent time gaining hands-on wine making experience in Australia, California and Oregon before undertaking formal education in œnology at Roseworthy Agricultural College in South Australia. After graduating he remained in Australia to gain additional experience before returning to Portugal in 1990 to join the Taylor Fladgate and Fonseca wine making teams. Since 1991 David has played a leading role in the production of the group’s wines and in the development of its wineries and vineyards. As Technical Director and head wine maker of The Fladgate Partnership he is responsible for the group’s extensive wine inventories. David also leads the team responsible for wine making in the group’s wineries and on the Taylor Fladgate, Fonseca and Croft estates. The research and development work carried out under David’s leadership has resulted in new vinification technology which has radically enhanced the quality of the wines made from the production of the group’s partner grape growers. David also works closely with the group’s head of viticulture, António Magalhães, one of the Douro’s most respected viticulturists and a world authority on mountain viticulture, in managing and developing the Taylor Fladgate, Fonseca and Croft vineyard estates.

WERNER MORANDELL. IT

Founder and Winemaker Lieselehof

Born in 1954, in the heart of the Italian Alps, Werner Morandell is one of the pioneers of sustainable viticulture. Since a young age, Morandell helped his father in the family’s vineyards and decided in 1993 to dedicate himself fully to his lifelong hobby of wine making. Quickly he realised the overuse and abuse of pesticides in viticulture and switched to organic methods. In 1998, Werner finds out about PIWI vines (vines resistant to Mildew and Peronospora) and decides to plant the first PIWI vineyard of Italy in 2002. Ever since, the pioneer has converted 80% of LIESELEHOF’s land into PIWI vineyards and was the vice-president of PIWI International and PIWI South Tyrol for more than 15 years altogether. PIWI International was the first association to promote pesticide free viticulture. As of today Werner Morandell has participated in many important conferences regarding sustainable viticulture and published two books covering this crucial topic.
His life’s work has enabled wine producers all over Europe to pursue a clean and healthy form of producing wines.
Today, at LIESELEHOF Winery, Morandell and his two sons produce award winning red, white and sparkling wines on the hills and mountains of the South Tyrolean Alps between 200 and 1250m.a.s.l. reducing the use of pesticides and chemicals between 90%-100%.
