The second half of the 20th century was marked by a radical transformation of the Champagne vineyards thanks to automation. Vineyard work has always required massive labor, but with the introduction of smart machines, vineyards have been able to redefine their practices. Specialized tractors and automated pruning equipment have enabled more precise and less labor-intensive interventions. Before automation, vine pruning was an extremely tedious and time-consuming manual task. Thanks to electric pruners and robotic pruning machines, winegrowers can now prune hectares of vines in a fraction of the time previously required. These advances have not only reduced labor costs but also improved the regularity and quality of pruning. Automated harvesting has also revolutionized grape picking. Harvest machines, introduced in the 1970s, allowed faster and more homogenous harvests, thereby avoiding the risks of oxidation and deterioration of the bunches. Additionally, these machines are equipped with technologies capable of sorting grapes directly at harvest, eliminating damaged or lower-quality fruits. However, some champagne producers continue to prefer manual harvesting for prestige cuvées, arguing that manual harvesting provides unmatched finesse and precision. For most harvests, however, automation has proven its effectiveness and positive impact on grape quality. The ecological impact of these machines has also been considered. Modern equipment is designed to minimize the carbon footprint, with cleaner engines and lower energy consumption. This environmental awareness is essential in an era where sustainability is at the heart of wine production concerns. Finally, automation has paved the way for precision viticulture.

These technologies provide real-time data on humidity, plant growth, and vine health, enabling targeted and efficient interventions, thus optimizing yield and quality.
Clonal selection and the use of resistant rootstocks have significantly influenced modern viticulture, bringing notable improvements in vine quality and resistance. These techniques, developed and perfected during the second half of the 20th century, have played a crucial role in the evolution of the Champagne vineyards. Clonal selection involves choosing the best individuals from a vine variety for reproduction by cloning. This method maintains specific characteristics such as disease resistance, plant vigor, and grape quality. Previously, viticulturists relied mainly on mass selections, choosing several vine stocks for reproduction. With clonal selection, they can focus on outstanding individuals, thus ensuring homogeneity and superior quality of the planted vines. Additionally, resistant rootstocks have revolutionized vineyard management against diseases and pests. After the devastating phylloxera invasion at the end of the 19th century, which nearly annihilated European vineyards, the solution found was to graft cultivated vines onto resistant rootstocks. Research in the 20th century developed rootstocks resistant not only to phylloxera but also to other pathogens and environmental conditions such as water stress or salinity. The incorporation of resistant varieties has significantly reduced the use of chemicals to fight diseases and pests. This directly impacts grape quality as vines can develop in more natural conditions, producing better-quality bunches. Furthermore, this approach promotes more sustainable and environmentally friendly viticulture. Advances in viticulture have also been accompanied by a better understanding of soils and terroirs. In-depth pedological studies now allow for choosing the best clone and rootstock for each soil type, thus optimizing yield and wine quality. In sum, clonal selection and resistant rootstocks have secured vineyards by making them more resilient to climatic and disease challenges while improving grape quality. These innovations continue to benefit champagne producers, allowing them to maintain high-quality standards while facing the environmental challenges of the 21st century.
The revolution of stainless steel tanks marked a major turning point in the production of champagne in the second half of the 20th century. Traditionally, champagne was fermented and stored in oak barrels, a method that, although classic, presented limitations regarding precise control over fermentation and maturation processes. The adoption of stainless steel tanks radically transformed this part of winemaking due to their numerous technological advantages. The main asset of stainless steel tanks is their ability to offer extremely precise thermal control. Fermentation is a delicate process that generates heat and requires careful temperature management to guarantee an optimal result. With stainless steel tanks equipped with sophisticated thermal regulation systems, winemakers can monitor and adjust temperatures with unmatched precision, ensuring more regular and controlled fermentations. Stainless steel tanks also offer superior hygienic guarantees. Since wine is a substance sensitive to contaminants, the non-porosity of stainless steel makes cleaning and sterilizing tanks between batches easier. This reduces the risks of infections and undesirable alterations, which could be challenging to manage with wooden barrels, likely to retain undesirable bacteria and yeasts. In terms of organoleptic qualities, stainless steel tanks permit perfect inertness. Unlike wood, which can add secondary aromas to wine, stainless steel is neutral and does not interfere with the grape and terroir’s aromatic characteristics. This allows champagnes to reveal purer aromatic profiles and highlight the grape variety and terroir’s typicity without the woody influence of barrels. More usage flexibility is also provided by stainless steel tanks. They can vary in size to accommodate different fermentation batch proportions, which is particularly useful for experiments and producing special small batches. Finally, the importance of stainless steel tanks is also measured in terms of durability. Stainless steel tanks are extremely durable and require less long-term maintenance than wooden barrels. Their longer lifespan and cave condition resistance make stainless steel an economically and environmentally sound choice. In conclusion, the adoption of stainless steel tanks has allowed champagne producers to significantly improve fermentation and storage processes. This innovation has not only enhanced the quality and safety of wines but also offered greater flexibility and increased durability for producers, helping them produce world-class champagnes more efficiently and sustainably.
Disgorging and dosage are crucial and delicate stages in champagne production. The modernization of these techniques has profoundly impacted the efficiency and quality of the final products in the second half of the 20th century. Disgorging, which involves eliminating the lees from the bottle after secondary fermentation, had long been performed manually. This traditional method, although precise and respectful of the product, was time-consuming and required great dexterity. The introduction of automatic disgorging machines revolutionized this step, allowing larger volumes to be processed more quickly and accurately. These machines are designed to freeze the neck of the bottle, cleanly and effectively expelling the lees by the pressure inside the bottle. This procedure reduces contamination risk and ensures impeccable consistency from one bottle to another. The next step, dosage, also known as liqueur d’expédition, involves adding a sweet solution to balance the champagne’s acidity. Previously, this step was also very artisanal, relying on the cellar master’s skill and experience. Modern automated systems today allow precise millimetric dosage, ensuring perfect homogeneity that respects the organoleptic characteristics defined for each cuvée. Advanced technologies also allow better oxygen management during these crucial phases. Oxygen can be both beneficial and harmful to wine depending on the amount and timing in the winemaking process. Modern equipment equipped with oxygen management systems minimizes undesirable oxidation and maximizes the benefits of oxygen input, thereby contributing to the product’s stability and uniformity. The automation of disgorging and dosage has also enabled champagne houses to innovate and experiment. More precise and reproducible adjustments can be made to create new and distinct taste profiles, meeting consumer expectations seeking exclusive and diverse products. Finally, these modernizations have facilitated better production cost management. Though the initial investment in automated equipment is significant, the savings in terms of time, error reduction, and human resource optimization are considerable.
