One of the most important phases in grape cultivation occurs after the harvest. The vineyards go through what we call "vegetative rest"; the vine loses its leaves and only the woody part remains. This phase occurs every year, from autumn in the months of March, April, and May, and throughout the winter of June, July, and August. The appearance of the plant is trunk, arms, and shoots. Only the woody part has no green structure due to the soil temperature. During those months in Ica, the climate fluctuates between 7°C to 13°C; there is no absorption of nutrients from the soil by the roots, which we call the rest or dormancy of the vine. From July onwards, the pruning of the vineyards begins. This is important because by reducing the number and length of the shoots, fewer clusters will be produced, allowing the shoots to thicken and improving the quality of what is produced in the vineyards. Ultimately, pruning prolongs the life of the vine and ensures the harvest year after year… Continue reading https://lnkd.in/eSaAQP_B Where pisco is the only protagonist! #lapiscoteca #piscosour #winelover #pasionporlacata #bar #elpiscoesdelperu #vino #vinosdelperu #pisco #piscolover #Lima #Peru @Piscorevista @elpiscoesdlperu @elmagozurdo @aspercat1 Photo by LPW Bodega Monte Carmelo Azpitia-Lima Peru

Why do we prune vines in winter? ❄️ 🍇 Vines are pruned in winter for several important reasons. Here are some of the main reasons: 1. Dormant period: During winter, vines enter a period of dormancy, which means they are inactive in terms of growth. This makes pruning easier and less stressful for the vines. 2. Clear view of the structure: When the leaves have fallen during winter, it is easier for viticulturists to visualize the structure of the vine, including the branches, canes, and buds. This allows them to make informed choices during pruning to shape the vine according to their production goals. 3. Growth control: Winter pruning helps control the growth of the vine by removing some of its old wood. This promotes balanced and consistent growth in spring, making vine management easier throughout the growing season. To discover the real Burgundy, contact Youri Lebault 🍷

https://lnkd.in/d7xSDD9f The vineyard is an ecosystem, and the vine is also a micro-ecosystem comprising the plant, and all the yeast, fungi and bacteria that live on and in it. What is most important is to do as little as possible. Not to overprotect the plants, and only to do something when it’s needed. We work in different ways in different areas. Already between Barbaresco and Barolo, I can see a lot of differences. In Barbaresco, for example, we have soils that are a little more sandy and more compact. We’ve been working to boost the different types of grass growing on the soil and to fill it with a nice, complex cover crop. This can be a bit challenging in Barbaresco because the soil tends to get drier than in Barolo where there’s more water-holding potential so that’s different.

The influence of geologists, many argue, is changing the game for Chilean and Argentinian wineries, helping them reach new levels of excellence and sustainability (specifically in the realm of water management. Knowing how soils retain moisture can help viticulturists more precisely determine the correct amount of water to deliver each vine). #terroir #geology #wineindustry #winebusiness #wine

🍇 #Veraison is happening in the Northern Hemisphere! 👇 Find here a selection of 4 articles published in #IVESTechnicalReviews linked to this important moment. The veraison marks the beginning of the #ripening process of the grapes, which finishes at the #harvest. Veraison can be defined as BBCH 85 Stage M: we consider that a berry has completed its veraison if it is soft to the touch. 👉 For more information about #vineyard and #analytical activities to perform from the veraison stage until harvest, dive into the following articles published on IVES Technical Reviews (technical articles available in 6 languages): 1 - Detailing ripening phenological stages: discrepancies, usefulness and proposal: https://lnkd.in/eSFyhzq6 2 - Leaf area management affects grape nitrogen content: https://lnkd.in/eSHxqPQA 3 - Aromatic ripeness may be the type of maturity that impacts red wine typicity the most: https://lnkd.in/eu-QYJXC (Part 1) and https://lnkd.in/eiQacK69 (Part 2) 4 - Plasticity of red wine sensory profiles: improved understanding through grape berry sugar loading profiles: https://lnkd.in/eab4qpUq 🌍 The articles are freely available in 6 languages: English, Français, Deutsch, Español, Italiano, Português. 👏 Thank you to the authors: Agnès DESTRAC IRVINE, (n°1) Pascal Marty, (n°2) Thibaut V., (n°3) Cornelis van Leeuwen, (n°4) Guillaume Antalick. #OpenAccess #viticulture #vine #climate #research #science

Situated at an average altitude of 500 meters above sea level, the four distinctive areas of our estate - I Poggi, Madre, Le Martine, and Ingresso - extend over a territory of 37 hectares of organically managed vineyards. Over time, detailed pedological analyses have guided us in dividing the land into 6 Macrogroups and 15 Soil Units, each representing a unique micro-terroir significantly different from one another, both in terms of soil type and vegetative development and ripening times. Each parcel thus becomes an autonomous "microcosm" that requires targeted interventions and continuous monitoring, allowing us to assess the ripeness level of the grapes from each unit and to schedule the optimal moment for their harvest, followed by separate vinification. Through research and enhancement efforts, we aim to convey through our wines the unique nuances of this microcosm in which we are immersed. . . . #PoggioAntico #PoggioAnticoWinery

Did you know pruning is the largest outgoing for time and labour costs during the growing season? 💡 So, could mechanised pruning be a better option for UK vineyards? 🤔 Our experienced viticulturist, Andrew Forgesson, shares the juicy details in Vineyard Magazine's latest article. With his long-term work in Australia and New Zealand, Andrew thought about how vineyards in these regions kept costs to a minimum and whether the UK could benefit from implementing these systems too. Could UK vineyards take on this way of pruning? 🚜 What do you think? Head to https://lnkd.in/eGKySqB4

Similar white chalk of renowned Champagne terroirs is also found in some areas of Hampshire 🍾 Below key points that describe these soils: Because only the upper soil does matter for vine roots growth and subsequently plant development & fruit ripening, only a few terroirs like these can claim that geology really influences wine style. These soils consist of a shallow, arable layer, 30-40 cm deep, on top of an extremely deep layer of pure chalk. Typically, 100 to 300 m of Cretaceous Chalk underlies these areas, forming extensive inclined slopes, undulating ground. 🤩 Chalky soils are free draining but only to a certain extent: check out the clay content of the topsoil and the percentage of slope to form an opinion. Even if chalk can retain a good amount of water, and significant capillary rise can be expected, these soils can be prone to drought (shallow soils + ground cover). Stones and rock fragments such as flint sometimes present within these soils can affect cultivation, particularly in organic viticulture. Note that the alkalinity of these soils can cause some nutrients to be unavailable. And a careless choice of rootstock will lead to irreversible damage. Nevertheless, chalk constitutes a fantastic subsoil for growing vines. And is it because these soils will fizz on contact with acid that they are perfect for sparkling wines?!🥂
