Insights from attending experts:

Dr. Laura Catena – Local wine producer, Catena Institute of Wine
“We are excited to greet sommeliers, wine lovers and wine trade who are interested in the subtleties of wine terroir. The study, preservation and celebration of terroir depend on the interest that wine lovers and consumers develop for this most important topic. The combination of an extraordinary natural setting, exciting presentations, and local food (bountiful asado-barbecue) and wine hospitality should make attending this year’s Terroir Congress in Mendoza the experience of a lifetime.”

Dr. Luciano Calderon – Argentinian geneticist and leading author of Malbec’s genome sequencing project
“As a geneticist, I consider that terroir is a combination of multiple variables, which all together constitute the scenario able to bring up the best or the worst of any combination of genes. Each cultivar, each clone and each plant is a unique combination of genes that expresses flavor in different ways, depending on its growing context, the terroir.”

Dr. Rodrigo Lo´pez Plantey – Professor and local symposium organizer at FCA UNCuyo, Argentina
“It’s a unique opportunity for Argentina’s wine industry to connect and collaborate with the international scientific community, together advancing our sector’s future.”

Dr. Kees Van Leeuwen – Bordeaux’s leading terroir academic
“The concept of terroir relates wine to its origin, the place where it is produced. Multiple terroir factors, including soil and climate, craft the taste of wine. Many researchers around the world work on explaining the mechanisms involved. These researchers gather once every two years since 1996 at the International Terroir Congress. The congress will take place for the first time in South America, in Mendoza, Argentina, from 18-22 November 2024. It is a unique occasion for an update on the most exciting terroir research and an opportunity to meet researchers from the terroir community in person.”

New study shows wine consumption does not increase cancer or mortality risk in healthy adults over 60

A study published this week in JAMA Network Open and conducted by researchers based at the Autonomous University of Madrid, Harvard and other institutions investigates the impact of alcohol consumption on mortality among older adults, particularly focusing on those with health-related or socioeconomic vulnerabilities. The findings reveal that even what is typically considered low-risk drinking can elevate mortality risks, especially for cancer and cardiovascular diseases. This is particularly pronounced among those with existing health or financial challenges.

Interestingly, the study highlights a protective aspect for those who predominantly consume wine and drink only with meals. This pattern seems to reduce the negative effects of alcohol on mortality, suggesting that the slower absorption rate of alcohol or the beneficial components in wine might play a role. The research underscores the need to address health disparities related to alcohol consumption, especially in vulnerable populations, and calls for further exploration into the benefits of wine consumption in these groups.

By understanding the nuanced effects of different drinking patterns, particularly the potential benefits of wine, the wine trade can better communicate with consumers and contribute to public health discussions. This study adds to the growing body of evidence that wine, when consumed in moderation and within specific contexts, might offer a protective edge against some of the health risks associated with alcohol.

An Exclusive Conversation with Maximilian Riedel, CEO and President of Riedel, by Liz Palmer

I am thrilled to conduct an in-person interview with Maximilian Riedel, the visionary CEO and President of Riedel, a company renowned globally for its innovative and high-quality glassware. Under Maximilian’s leadership, Riedel has continued to elevate the art of glassmaking, blending tradition with cutting-edge design to enhance our wine and spirits experience. In this exclusive conversation, Maximilian shares insights into the company’s journey, his personal inspirations, and the future of Riedel in the ever-evolving world of glassware craftsmanship. Let us delve into the mind of a leader who is redefining the way we savor our favorite beverages.

Company Vision and Strategy

Riedel has a long and storied history in the glassware industry. How do you balance tradition with innovation in your role as CEO?

“So, obviously, tradition is for me an orientation, but I see it in my back mirror, and sometimes it’s good and advisable to look into the back mirror, but it should never interfere with the cause of an entrepreneur.

We are in the present, we’re working for the future, and sometimes you also have to break with tradition to bring forward newness and excitement, and that’s exactly what I have been doing over the last 10 to 20 years.

So, I feel like I am in the midst, and I’m doing a good job in balancing them both.”

Product Development and Innovation

How does Riedel approach sustainability and environmental responsibility in its manufacturing processes?

“For us, this, of course, is a very important subject, especially since we live off raw materials, which are natural.

Lately, very challenging for any manufacturer in Europe because the cost for energy and raw materials has gone through the roof, and it’s challenging for us right now.”

Are there any upcoming products or innovations that you are particularly excited about?

“Always, but we remain creative, and every year we bring forward newness, and invest in our technology which allows us to bring forward products which are very unique to the market.”

Market and Industry Trends

How do you see the global market for luxury glassware evolving in the next 5 to 10 years?

“Amazing. I think we have not seen so much development like we did in the past 10 years.

Sadly, it’s coming to a halt because the wine industry is not booming anymore, and because of that, it’s a little bit challenging also for us as glassmakers because we are so connected.”

Personal Insights and Experiences

Growing up in a family business, what are some key lessons you learned from your father and mother?

“From my father and mother …everything, everything.

I’m in the business because of them.

They made it so exciting and so attractive to me that I wanted to join ever since, and the reason why I’m here is because of my parents.”

What motivates you both personally and professionally?

“Well, I’m living the dream.

I mean, who does not want to deal with wine and food and glass every day. I get to travel the world…. I get to meet very interesting people.

Also, thanks to social media, in my little environment, I’ve become a celebrity because of my passion for what I do.”

Future Outlook

What partnerships or collaborations are you currently exploring to expand Riedel’s reach and influence?

“Well, obviously we have a lot of partnerships with wine and champagne houses, but I think we need to look outside of that because we learned from Tiffany and other companies… right now partnerships with other companies, with other brands can be of great benefit so, we’re seeking for that.”

Maximilian Riedel’s Favorites

Let’s dive in and learn about your favorites.

What is your favorite Riedel Collection and why?

“I don’t have one because I love them all, otherwise I would discontinue them. I love them because of what they stand for and whatever comes handy, I use.”

What is your Favorite Decanter and why?

“Definitely the Ridel Eve Decanter, it’s one of many designs that I created… it’s my favorite.”

What is your favorite wine (if you had to choose one) and why?

“Don’t have one….It depends on the situation, depends on the momentum, depends on the people I’m with.

But, if it comes to champagne, I grew up with Dom Pérignon, and for sure it’s a wine I would look at.”

And lastly, my most important question [I also love vintage cars especially sport cars]…whilst your passion for wine runs deep, so does your love for collecting and driving your vintage sports cars on the track, through vineyards and through the European countryside, which car do you favour overall to drive through the vineyards?

Well, it’s similar to wine. I’m fortunate to have a few cars, and it’s also about the situation and the momentum. Cars are like beautiful pairs of shoes. You have one for every occasion, or you should have. I definitely have a passion for Porsche cars, and vintage Porsches with their air-cooled sound it’s very special.”

European Commission sets out the continent’s first soil law

Amid intense opposition to proposed laws on nature restoration and curbs on pesticides, the European Commission put forward proposals [the continent’s first soil law] in Brussels last week to revive degraded soils. Research indicates that this could help absorb carbon from the atmosphere and ensure sustainable food production.

The new law would see Member States monitor the health of soils, fertilizer use and erosion, but stops short of country-level targets for improving soil quality. This drew criticism from the European agri-food industry, which called for more ambition to improve the “worrying” state of soils.

The EU estimates at least 61% of the bloc’s soil is unhealthy, driven by factors including degradation of peatlands and intensive fertilizer use.

EU environment commissioner, Virginijus Sinkevičius states:

“If our soils continue to degrade, the biggest risk is to our food security and farmers. Basically, their business model is wiped out,” he said. “I can hardly imagine how we could do agriculture without fertile soils. The worst effects of droughts and floods can be avoided with healthier soils.”

The new law would not have legally binding targets, although “We are opening the way to additional income opportunities for farmers and landowners through a voluntary certification scheme for soil health and strong synergies with carbon farming and payments for ecosystem services,” Sinkevičius states.

One Planet Business for Biodiversity (OP2B), the main representative of the European agri-food industry in Brussels, said the proposals did not go far enough. “The EU needs to go further to tackle the trend of deteriorating soil health in Europe,” said director Stefania Avanzini.

The European Commission is calling on Member States and the European Parliament to raise the ambition of the proposal. “We very much value the importance the commission gives to agriculture and its central role in the management of soil,” Avanzini said.

 

Ancient wine grapes related to today’s grape varieties, research shows

“A recent international study led by two Israeli universities analyzed 1,000-year-old seeds which were discovered at archaeological excavations in the Negev; the findings are ‘significant for Israel’s modern wine industry” research scientist states

A recent study led by the paleogenetic laboratory of the Steinhardt Museum of Natural History at Tel Aviv University and the University of Haifa analyzed DNA from ancient local wine grape seeds discovered at archaeological excavations in the Negev.

One seed was found to be almost identical to the Syriki variety used today to make high-quality red wine in Greece and Lebanon, while another seed is a relative of the white variety called Be’er, still growing in deserted vineyards in the dunes of Palmachim.

The genetic study was led by Dr. Pnina Cohen and Dr. Meirav Meiri of the paleogenetic lab at the Steinhardt Museum of Natural History at Tel Aviv University. The seeds were found at archaeological excavations led by Prof. Guy Bar-Oz from the School of Archaeology and Maritime Cultures at the University of Haifa, in collaboration with researchers from the Israel Antiquities Authority. Other participants included researchers from the University of Haifa, the Weizmann Institute, Bar-Ilan University, and research institutions in France, Denmark, and the U.K. The paper was published in the journal Proceedings of the National Academy of Sciences.

“Archaeological excavations conducted in the Negev [Israel] in recent years have revealed a flourishing wine industry from the Byzantine and early Arab periods (around the fourth to ninth centuries A.D.), especially at the sites of Shivta, Haluza, Avdat, and Nizana, which were large, thriving cities at the time,” says Prof. Guy Bar-Oz from the University of Haifa.

“The findings include large winepresses, jugs in which the exclusive wine, exported to Europe, was stored, and grape seeds preserved for more than a thousand years. This industry gradually declined following the Muslim conquest in the 7th century, since Islam forbids the consumption of wine.”

“The cultivation of wine grapes in the Negev was renewed only in

Modern times, in the state of Israel, mostly since the 1980s. This industry, however, relies mainly on wine grape varieties imported from Europe.”

One especially interesting finding was a large hoard of grape seeds, discovered on the floor of a sealed room at Avdat. The researchers explain that these seeds have been relatively well-preserved thanks to protection from climatic phenomena such as extreme temperatures, flooding, or dehydration. To learn more about the seeds, in the hope of discovering which varieties they might belong to, the researchers prepared to extract their DNA in the paleogenetic lab.

“The science of paleogenomic uses a range of advanced technologies to analyze ancient genomes, primarily from archaeological findings,” explains Dr. Meiri from the Steinhardt Museum of Natural History at Tel Aviv University.

“Since the DNA molecule is very sensitive and disintegrates over time, especially under high temperatures, we usually get only small pieces of DNA, often in a poor state of preservation. To protect them we work under special conditions: the paleogenetic lab is an isolated clean laboratory, with positive air pressure that keeps contaminants out, and we enter it in sterilized ‘spacesuits’ familiar to everyone from the COVID pandemic.”

To begin with, the researchers looked for any organic matter remaining in the seeds. For this purpose, they used FTIR (Fourier-transform infrared spectroscopy)—a chemical technique applying infrared radiation to produce a light spectrum that identifies the sample’s content. Finding remnants of organic matter in 16 seeds, the researchers went on to extract DNA from these samples.

The extracted DNA was sequenced, with an emphasis on about 10,000 genomic sites where variety-specific features are usually found, and the results were compared to databases of modern grapevines from around the world: In 11 samples, the quality of genetic material was too poor to allow any definite conclusions. Three of the remaining samples were identified as generally belonging to local varieties. Finally, the two samples of the highest quality, both from around 900 A.D., were identified as belonging to specific local varieties that still exist today.
