Episode Summary

Content Analysis Key Themes and Main Ideas 1. Professor Shenza's advanced seminars on Italian wine soils and terroir. 2. Detailed examination of specific Italian soil types, particularly metamorphic schist in Sardinia, and the impact of iron content on soil color. 3. The influence of topography (slopes and valleys) and microclimates on temperature variations, grape ripeness, and the development of aromatic compounds in wine. 4. The redefinition of ""mineral wines"" as a result of a plant's reaction and defense against its surrounding climate rather than direct mineral absorption from the soil. 5. The significance of traditional, manual viticulture practices in challenging terrains and how wine is a combination of human effort and environmental factors. Summary This segment of the Italian Wine Podcast features Professor Shenza's advanced seminar, focusing on Italian soils, particularly those of volcanic and metamorphic origin. The discussion delves into a specific area in Sardinia known for its metamorphic schist, highlighting how high iron content gives the soil its distinctive red color. Professor Shenza explains how topographical elements, such as slopes and valleys, create microclimates that influence temperature fluctuations, affecting grape ripeness and the development of various aromatic compounds like norisoprenoids and monoterpenes. A key point is the reinterpretation of ""mineral wines,"" asserting that their characteristics stem more from the plant's adaptive responses to its climate and terroir than from direct mineral absorption. The seminar also compares clay/schist soils with sandy/granite soils and emphasizes the necessity of manual viticulture in Sardinian vineyards due to steep slopes, concluding that wine is a profound combination of human effort and the natural environment. Takeaways * Italian wine seminars frequently delve into the complexities of regional soils and their impact on wine. * Metamorphic schist soils, particularly in Sardinia, often derive their red color from high iron content. * Microclimates created by topographical features significantly influence grape development and wine aroma profiles. * The concept of ""mineral wines"" is deeply tied to how grapevines adapt and react to their specific environmental conditions (terroir). * Traditional, manual viticulture remains crucial in many challenging Italian wine regions. * Wine quality is ultimately a synergy between human viticultural practices and the natural environment. Notable Quotes * ""The higher the iron the iron give the, the red color."

About This Episode

Speaker 3 discusses the geology of the Ross Sea region in the Ross Sea region of Italy, where the river valet and the sun affect the colors and characteristics of the wines. They also mention a study on the differences between two types of soil in wines, with the sun being a factor in the ratio of iron and oxygen.

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 Shenza. Oh, and for all those English speakers only in the house, Shenza's sidekick Francesco Marchio was there to back him up all the way, translating all the material on the spot. Chinchin wine nerds. Before the show, here's the shout out to our new sponsor, Ferrowind. Ferrowind has been the largest wine shop in Italy since nineteen twenty. They have generously supplied us with our new t shirt. Would you like one? Just two fifty euros and it's all yours. Plus, we'll throw in our new book jumbo shrimp kite international grape varieties in Italy.

The metamorphic areas of volcanic origin is not that big in Italy. It's mainly on the Alps. And, we will talk today about the Sardinia, a specific area or Sardinia, where we have, some Viticulture, some quality Viticulture, then we can, discuss all about this this soil. The. Yeah. This is the most important area in Sardania. It's in here too for metamorphic schist and is on the eastern southeastern part or Sardinia. Where is the production of, Canada. The are a picture of the the And, they they are formed by small layers, because the material was melted and solidify very slowly. That's why the layers are are are smaller than, than, than, shorter than the other, picture that we saw before. And on the, the right picture, the, the red soil is a demolition of the soil of the dischis. That's how they became. Yeah. The the higher the iron the iron give the, the red color. Okay. The. The area So, yeah. This is a picture of, a hill and a year or two. So you see the slopes is divided in four different area with a being the highest and d is the the bottom valley basically, what's happened, the cold hair goes down, and, when it goes down, it gets warmer. And then when it eats the bottom of the valley, it starts to come back. So it starts to go up again. So this, what it does, that should keep cool all the the hills and also, make a great deeper than different variation in temperature between night and day, and, it also affect the ripeness. Effecting the ripeness also will affect the aromatic compounds of the wine. So we have going down the, noise, openoids are actually higher while the monitor pins going up that are higher. You see plus and, and minus. So this is, an important study that professor carry out here to understand once again how the soil, the geology affect the the wines we will see in the next slide. Since this is the hill, and, the first of all says something, very interesting. The the hills are made of clay sheets, slopes. The the creation of this difference of, aroma noise, ochronoids, turpents, benzanoids, they're not made by, the plant to to please us. But, because the plant is, you react and defend the, itself by the, the, the surrounding, climate. So when it gets hotter, when it gets cooler, it start to create these, compounds to to to compensate. So this is why it's, it's very important, professor say many times, the, you know, mineral wines, It's not because the mineral and the soil, but it's more has to do with the the plant, how the plant, behave, how the plant is actually acting in a certain, area, certain climate and terroir. Yeah. So this this create, different difference between the the slopes in, in red, Verzanti, or the fond of Valle, the river valet in blue. On the, on the slopes, the tunings, for example, are higher. And, on the river valet, the the fruity nodes are higher instead. So this is a very, very interesting to see how the, you know, altitude actually affect the, the the the aroma compounds in the in the wine. We do, let's do it in some position to the, pedologic, a geological pedologic, the Yeah. Yes. We have two t different type of soil, the clay soil, so the sheasty soil, from the sheasts. These are, red in color because there is more iron in there. And then on the right side, you have the sandy soil. So these are derived from granite. And there are this picture that show us, the difference between the two. Yes. This is the art art work of the the people in this part of, Sard is is not possible to have a machine in the vineyard because the, the the the slopes, and this is a, a, a type of, ox. And, and it's still everything is manual, you know, like, they used to do. So the the the the wines, the results, the one that we have is, combination of demand and, and environment. That's that's what it is. Very. Perfect though. Listen to the Italian wine podcast wherever you get your podcasts. We're on SoundCloud, Apple Podcasts, Spotify, EmLIFM, and more.
