Summary: 

Climate is a pervasive factor in the success of all agricultural systems, influencing whether a crop is suitable to a given region, largely controlling crop production and quality, and ultimately driving economic sustainability. Climate’s influence on agribusiness is never more evident than with viticulture and wine production where climate is arguably the most critical aspect in ripening fruit to optimum characteristics to produce a given wine style.

This webinar will provide an overview of regional to global research on: 1) aspects of terroir that influences optimum quality and production characteristics; 2) the suitability of different winegrape cultivars to different climates; 3) how climate variability influences production and quality variations; 4) how climate change has and will likely continue to alter the global wine region map; and 5) measures being taken by the wine sector to mitigate and adapt to changes in climate.

Presenter: Greg Jones

Greg is a world-renowned atmospheric scientist and wine climatologist, having held research and teaching positions at the University of Virginia, Southern Oregon University, Linfield University, and as an adjunct professor at the University of Adelaide. He has taught extensively across many areas including meteorology, climatology, ecology, hydrology, geology, statistics, GIS and remote sensing, and wine business, viticulture, enology, and sensory evaluation.

For over twenty-five years his research has firmly linked weather and climate with grapevine growth, fruit chemistry, and wine characteristics in regions all around the globe. His work was also one of the first to tie climate change to fundamental biological phenomena in vines and the resulting influences on productivity and quality, informing and influencing the wine industry worldwide. Greg has served on the editorial advisory boards of multiple international and national scientific journals and organizations and serves as a Director on the Oregon Wine Board and the Erath Family Foundation board.

Summary: 

Sustainable wine growing can cover various practices from farming to production techniques, environmental and social policies, and even packaging and waste reduction choices. The challenge for wineries is how to present their sustainable principles and practices to consumers.

This webinar will focus on the importance of sustainable certification programs around the world, such as Napa Green, and how they are helping to shape the conversation about what is sustainable in the age of climate change, and how to move the wine industry forward using measurable data and accountability.

Join vigneron Olivier Humbrecht MW, of the famed estate Zind Humbrecht in Alsace, for a deep dive into one of the key building blocks of wine: acidity!

In this WSG Live, you will learn about:

• The different types of acids found in grapes and wine and their sensory perception
• How to not only quantify but qualify acidity in wine
• The viticultural factors influencing acidity in the grape
• The vinification practices and factors impacting acidity in the final product
• Evolution of wine acids with age

Olivier will also illustrate his talk with some real-life data and text-book examples of acids measured in various types of wine depending on various variables such as grape varieties, vintage, ripeness, with/without malolactic fermentation and terroirs.  Sharpen your tasting skills by understanding one of the key parameters that makes up the structure of a wine!

Presenter: Olivier Humbrecht MW

Olivier Humbrecht studied wine together with wine marketing and wine business for five years in Toulouse, and then got the chance to do his ‘military service’ working for Sopexa in London. 

He learned about and enrolled on the MW course, becoming France’s first-ever Master of Wine in 1989.  He began to work with his father and converted the family domaine to biodynamics in the early 1990s.  His father had painstakingly built up a unique collection of hill-site vineyards over the decades, notably clearing and replanting a quarter of the great historic Grand Cru of Rangen de Thann with Olivier in his later school years. 

Olivier has continued to build on this, notably with the recent acquisition of a parcel of Sommerberg to complement the family’s Grand Cru holdings in Brand, Hengst and Goldert, and to complement its other holdings of Rotenberg, Clos Hauserer, Clos Jebsal, Heimbourg, Herrenweg and Clos Windsbuhl.

Olivier’s respectful, non-interventionist winemaking, combined with his and his father’s fastidious viticulture, has given the world vintage after vintage of magnificently differentiated, nuanced bottlings: global white-wine references.  He has never stopped experimenting and improving on his work, using biodynamic practices, changed row orientations and re-thought canopies recently to produce a much greater percentage of dry wines than before.

Finally, we have reached the end of the winemaking year. 

In the vineyard, soil health is a common topic of discussion now that the vines are dormant.  This is a great time to dig soil pits and send samples off to discover more about the composition of the soil layers around the root system of the vines. 

Soil pH plays a large part in the health of a vineyard as it controls nutrient uptake.  Even if the soil contains plenty of a particular nutrient, if soil pH is wrong, that nutrient might not be available in a form that the plant can use.  This can lead to micronutrient deficiencies or toxicities. For this reason, it is very important to manage the soil pH.

Summary:

Have you ever tasted a Souvignier Gris, a Solaris or a Bronner? What about Regent, Cabernet Cortis or Rösler? These are just some of the disease-resistant varieties that have been bred over the last few decades from complex crossings of vitis vinifera cultivars with American sub-species such as vitis labrusca, vitis riparia or vitis rupestris.

What started as a crude exercise in creating new plant material in the wake of the turn-of-the-century phylloxera catastrophe has become a cutting-edge niche in wine production. Varieties are being developed that have resistance to cold, drought, or to common vine ailments such as downy mildew and botrytis. This has opened the door to a form of viticulture that requires almost no inputs apart from pruning.

Should we call these varieties hybrids or PIWIs or something else? And how is a hybrid different to a crossing or a “direct producer”? Does laboratory crossing of grape varieties overlap with gene-splicing, CRISPR9 or GMOs? Where are the boundary lines in these techniques and what do they mean for viticulture and wine in general?

We’ll talk about why winemakers from France, Austria, the Netherlands, Italy and beyond are planting hybrids. Hybrids might just be the future in wine. So join me for this session if you want to stay ahead of the curve!

At the start of November, areas with long growing seasons are still wrapping up harvest, but most wineries in the northern hemisphere have brought their grapes into the winery.  An exception to this rule is any fruit being left out for ice wine production.

Ice Wine Production

Grapes destined for ice wine production must hang on the vine until temperatures reach a consistent 20°F/-7°C or below. Only at this point, can the frozen berries be harvested.

November begins with a lot of activity in the winery and ends with everyone taking a collective sigh of relief.  The growing season is at an end and most wine production professionals can take a moment to reconnect with their families and friends and take a well-deserved vacation. 

In October, most areas of the northern hemisphere are in harvest and going full out!

Many white varieties finish in early October. Although some reds (particularly early-ripening Pinot Noir) may have started harvest in September, generally, October is the month when most red varieties are picked. 

In September’s post, we explored the harvest parameters for white grapes.  The factors that a winemaker considers when picking red grapes are similar… flavor, acid, sugar, etc.  However, there are two key harvest parameters that are more important (and impactful) for reds than whites: tannin ripeness and anthocyanin accumulation (color).
