Episode Summary

Content Analysis Key Themes and Main Ideas 1. The geological origins of Italian soils, specifically glacial (morainic) formations. 2. The impact of the Quaternary glaciations on the Italian landscape, particularly the Alps and the Po River plain. 3. Detailed exploration of wine production areas influenced by glacial deposits, focusing on Lugana (Lake Garda) and Franciacorta (Lake Iseo). 4. The formation of lakes and morainic deposits as glaciers retreated. 5. Different types of morainic soils (e.g., chaotic deposits, limous/clay vs. coarse material) and their significance. Summary This segment from the ""Everybody Needs a Bit of Shenza"" series, part of the Italian Wine Podcast's advanced wine seminars, delves into the ""ice wines of moraines,"" clarifying that this refers to wines originating from glacial deposits, not sweet wines. Professor Chienza, with translator Francesco Marcio, explains the influence of the third and fourth glaciations (Quaternary era) on Italy's geography, particularly the formation of lakes (Garda, Iseo, Como, Maggiore) and the subsequent moraine deposits. The discussion focuses on Lugana and Franciacorta, highlighting how the movement and retreat of glaciers created unique soil compositions. The presentation details how lakes formed in crust fractures filled by ice, leaving behind varied deposits (chaotic, stone, limous, clay) as glaciers melted. Differences in soil types within Lugana itself (e.g., from different glacial influences or river deposits) are also noted, emphasizing the impact of these geological formations on wine-growing regions. Takeaways * ""Ice wines"" in this context refer to wines from soils of glacial origin (moraines), not sweet wines made from frozen grapes. * Italian glaciation primarily occurred in the Alps and influenced regions like Lugana and Franciacorta. * Lakes in northern Italy (Garda, Iseo) were formed by ice filling deep geological fractures. * Glacier retreat left behind distinct morainic deposits, creating diverse soil types (e.g., chaotic, coarse, limous/clay). * Soil composition within glaciated regions can vary significantly (e.g., Lugana vs. Bardolino, or different terraces), impacting viticulture. * The movements of glaciers transported and deposited materials, shaping the wine regions' unique terroirs. Notable Quotes * ""So it's not the ice wine made, you know, the the sweet wine, but the wines originated from, Maureen, from the, the glacial origin."

About This Episode

The speakers discuss the history of Italian wines and give a brief recap of the master class. They also discuss the geography and production area of Italian cities, including Laco G Za and Laco B born, and the importance of the moraine in the lake and river. The differences between the two regions of the river, with the Cardium being more defined, are explained by the different glassation and type of deposit, and the river deposit is more defined. They conclude by reminding listeners to subscribe to their podcast and donate through Italian wine podcast dot com.

Transcript

Welcome to another installment of everybody needs a bit of Shenza. Class is in session. Follow the professor, in his advanced wine seminars during the Venetal International Ambassador Certification course flagship edition in verona. Seminers were on the ten must known Italian soils, Evinid el Foco, Evinid elmare, and Evinid el gacho, just in fire, water, and ice. Very game of Thrones, but way more nerdy. And, of course, starring our very own superhero, Professor Chienza. Oh, and for all those English speakers only in the house, Chienza's sidekick Francesco Marcio was there to back him up all the way, translating old real on this spot. Chinchin wine nerds. Hi, everybody. Italian wine podcast celebrates its fourth anniversary this year, and we all love the great content they put out every day. Chinching with Italian wine people has become a big part of our day, and the team in verona needs to feel our love. Producing the show is not easy folks, hurting all those hosts, getting the interviews, dropping the clubhouse recordings, not to mention editing all the material. Let's give them a tangible fan hug with a contribution to all their costs, head to Italian wine podcast dot com, and click donate to show your love. So this morning, we have the the last part of the master class of Italian soils, and we talk about the ice wines of Maureen's. So the wines that are, have origin from, a glacial origin. The professor will, introduce, two different area today. We will talk about Lugana and Franca Corta. So let's get started right away. In in in Canada. Italian. Yeah. So we had, for the professor, mentioned what I just say about the ice wine. So it's not the ice wine made, you know, the the sweet wine, but the wines originated from, Maureen, from the, the glacial origin. And, the all the the origin is starting from the fourth glacation, and we'll talk up today about the third and the fourth glacation. The fourth glacation is the last one happened in the quaternary area. Okay. Yeah. So the causation in Italy, they're restricted to the area of alps. And, Abruzzo on the Maliela mountains. In Germany of the geographies in italian in Shublrica. Yeah. So today, we'll talk about we have the north in Italy four different lakes, Lagogore, Lagogarda. Lago de isao and Lago de como. Today, we will talk about, two lakes and two wine production area. The first one is the Laco Garda, for Lugana. And the second one is the Laco Bizio for Franca Corta. And then the first slide, you'll see, the Laco Guarda on a max expansion during the globalization. And and the second one went actually, at the end of the conversation. On the second picture, the one below, you will see, the legal guard that left a number of deposit bridges. Which we these are the the moraine that we will talk about today. Okay. And, yeah, so the the lakes, were formed, with the the two, the the African, late pushed up the, to the continental, the European one. And, there was a fracture in the, in the crust, and this fracture were filled by the highs during the glassation. So this is how, the, the lake were formed when the the glassation handed, he left behind the lake and also the deposits. Yeah. So here, in in this slide, we'll see the Italy before the mentee of the glaciers in the last glacation. Geological time is on the left side during the places and in the quaternary. Professor was mentioned that, the the highs, the glacations up before the Aluvienal plane of, Paul River. And it's interesting also to notice that, Italy is, much bigger. The surface of the country is bigger. You can see is, attached to the eastern part of the arctic sea. Okay. This equation will change, soon when, after the glassation, when all the highs will be melted. And so the the the adiatic sea level will rise up and cover the lands. This is, while also we also mentioned yesterday, This is the reason why we have all these deposits. So the water going up and down. Same things that we say about the the Iranian seed get dry and get fill again with water. A Okay. Yeah. So this is a picture of, the Lake of Garda during the play place to send. The professor was saying we're talking about the fracture in the Lake of Garda was very deep. It was around three hundred meters, deep at the fracture. And this was filled as we just mentioned with the with the highs. When the highs started melting, the the glacier retreat and left the deposit behind. And that's how the moren were formed. So the movement of the glacier back and forward, with the glassation, they actually bring the deposit down. And then when we treat, lift the deposit behind. So that's the movement of the the glass the glass shell. Okay. So the region of, the is the northern part is, from Merano as, volcanic and, metamorphic origin. So that, that means it's important because, we need to understand which kind of material the glacial deposit after the, started to retreat. So the first part, is a volcanic region, and the second part as dolomitic origin. And this is the reason on, why we found various type of deposit, actually, are called chaotic deposit because it's a mix of different, origin. This will be different. We will talk later about, French Corta. So the lugana and the Garda are, different type of, material that deposit different original comparative Frencha. The year, the professor divided the two area in and Bardolino. You will see here this, circle, semi circle. That's actually, the the defined, the different glassation, and the different type of, of deposit. The two Harry and Bartolino are very different. Because the Bardolino was formed also from the deposit, brought from the river Adije. So there was a a different, glacial. It's not the same of, of the one of stores. So we have more deposit here, critically deposited. What what type of deposit? So it's more of the material in then you have the It's interesting to see the difference between the two areas. It's it's more defined. It's, the the shape is actually free, same, same circle. Instead on the Bardolino area, is not so defined as a, in lugana because, you have the influence of this alto alijer River deposit that they create different situation in terms of the material and deposit. These are images of, the front of the class So we are now, we will talk about this, the last part of the glacial. Will, prima in prima deposit. Okay. It's deposit. They'll, in prima deposit, they will get Yeah. We have here, the the comment errors. It's the first deposit of the glacial when, when they start to retire, go back. Okay. So, once again, when the the glass starts to go back, creates, a dam, a barrier. This is the terrace of Kame. These are the first deposit left. It's called terrace because it can be on the gloucher movement when it goes back. It can be in a different time. And so every time you leave some deposit and then you create the kind of terrorist, The interesting the the the picture that we are more interested in is the one on the left side. And, when the the picolashes go start to, go go back, it live behind, a small river. Yeah. So, and this river is actually, the river who, don't drop all the material. And this is very important because here is the area that we create the moraine. They'll, they'll go through. These, soils are very different from the other soils. So the the the soils made on the download area of, of the glacier are very different from the camera areas, for example. Where where the river, deposit the material is mainly limous and clay. Instead, on the camera terrace are mainly stone, a coarse material. So these are the more thinner material and, the the quality. And different quality. The quality is also in lugana. It's a very, different where your vines are planted. Listen to the Italian wine podcast wherever you get your podcasts. We're on SoundCloud, Apple Podcasts, Spotify, email ifm, and more.
