Many wine regions are doing research to better understand the challenges posed by climate change. In the recently inaugurated Bragato Research Institute in Blenheim, Marlborough, in New Zealand, 84 small fermentation tanks and a lot of other necessary equipment, some in miniature format, will enable various research projects for both viticulture and vinification. After two […]
The idea seems brilliant. The company De Sangosse has developed a new product, a so-called adjuvant, named LE 846, whose viscous and liquid properties help to reduce the spraying by a quarter against downy and powdery mildew, two difficult fungal diseases. This adjuvant will reduce the amount of fungicide remaining in the air. There will […]
How is it possible for some wines to cost so little? Is it about mass production, about advanced industrialization? A new project run by Anivin de France, the association of producers of Vin de France, in collaboration with the research institute Institut Français de la Vigne et du Vin, shows how to mechanize more efficiently […]
Pierce’s disease affects vines especially in California and the rest of the United States. But it exists also in South America. The disease is spread through insects called sharpshooters. It is difficult to cure and the vines usually die within five years. Now, the University of California Davis has released five new grape varieties that […]
Can the solution to the problem of the dreaded fungal disease downy mildew (mildiou) be something as simple as oregano? It is a little early to answer yes to that question. But the experiments that two Swiss researchers are currently doing are interesting. They discovered that by spraying essential oil of oregano on chasselas grapes […]
Organic wines are becoming more and more popular with French wine consumers. 48% of them would like to see a larger range of organic wines in the stores where they normally buy wine. The fact that the wine is organic is a buying argument for 50% of the young and 38% of the older consumers. […]
Walla Walla, a well-known wine region in Washington State, was believed to be exempt from the vine louse (phylloxera vastatrix). Therefore, the recent discovery of the louse that is so dangerous to the vines dealt a heavy a blow to the wine producers. All of Washington, and especially Walla Walla, has the kind of sandy […]
Wine producers are facing difficult choices today. Not least in what way they should manage the vineyard. Conventional, sustainable, organic or biodynamic? They have a variety of pesticides to choose from. More if they grow conventionally, less if they are organic. However, there are very different opinions about how dangerous these products are (e.g. glyphosate) […]
The harvest in Champagne was in full swing when we kicked off our autumn wine tour season with Champagne on September 11. And we mostly saw happy faces. Alexandre Penet at Champagne Penet-Chardonnet in Verzy looked very pleased when he talked about his healthy-looking grapes. Charles Philipponnat at the eponymous small prestige house in Mareuil-sur-Aÿ […]
Natural wine is here to stay. And although the EU has said that there will be no official rules for this category, it does not prevent private groups from setting up their own. As, for example, Vinnatur in Italy (www.vinnatur.org) has done. Now Sébastien David, winemaker in Saint-Nicolas-de-Bourgueil in the Loire Valley, is trying to […]
The discussion about the future of glyphosate continues. It is very contested if glyphosate is dangerous or not at all dangerous (when properly used). In 2022, it will again be on the EU agenda, until then it is allowed. But France (at least the government, but not all farmers) wants to ban glyphosate before that. […]
During flowering, the winegrower looks anxiously at the weather forecast. The flowering takes place, depending on the region, from the end of May until the end of June. This year it was early in some places in France, for instance in Bordeaux. When we were there on the first days of June it was in […]
The department of Hérault accounts for a large part of Languedoc’s wine production. A wine production that may be in danger if they do not increase the irrigation area, they worry. At present, almost 35,000 hectares of the vineyards here are irrigated (of a total of just over 90,000 hectares). A project is now underway […]
The vine is in many ways a robust plant that can withstand difficult conditions and drought. But it has weaknesses. One is that it is prone to fungal diseases. No vineyard can survive without spraying. Have you heard the opposite? Don’t believe those who tell you that some wine is made without the use of […]
The spring frost has struck again in several places in France. Warm spring weather led to an early budding but then the weather changed again, as it usually does. In the Loire Valley, they are now experimenting with a new way of protecting their vines from spring frost, which can potentially cause major damage. The […]
If drought is a recurring feature of the weather, then the wine growers become experts in handling it. This is the case, for example, in South Africa. Here they have learned how to optimize irrigation so that the vines get exactly what they need and not one drop more. Heinrich Schloms is a soil scientist […]
When we talk about countries with non-grafted vines, most people think of Chile, the only country in the world that is completely free from phylloxera, the small wine louse that infects the wine roots and kills the vines. But also in Australia a significant proportion of the vineyards are planted with non-grafted vines. However, the […]
Today, an organic wine farmer who wants to plant new vines can buy the same vines from the nursery as a conventional wine farmer. But this will change. New rules, although not until 2035, will require organic wine producers to buy organic certified plants. The nurseries are already preparing. And the authorities are busy writing […]
Older vines give more character to the wine, says Rosa Kruger, a well-known South African viticulturist. She is behind a project called South Africa’s Old Vines Project, which aims at finding old vineyards, vineyards that have often been abandoned. The idea with the project is to give a new life to these old vines. A […]
When some people think about machine harvesting, they often imagine big monsters that brutalize the vineyard. It is true that harvesting machines are often big machines, but they can be quite gentle to both grapes and vines. And soon there will be on the market a tiny harvesting machine, suitable for the small producer and […]
The European Commission has now voted on the future of copper in European agriculture. On November 27, the decision was made to lower the limit to 4 kilograms of copper per year and per hectare counted as an average over a 7-year period (in other words, 28 kg in 7 years). This 4 kilos average […]
It is amazing how different vineyards look today compared to 30 years ago. Then, there was not one single straw of grass in the rows between the vines. Today vineyards are often vibrant and colourful with different plants and flowers to keep the vines company. But they also compete with the vines for water and […]
Many consumers perceive wines nowadays as more alcoholic than they used to be. This is actually quite true. This has to do with a lot of things (and not only global warming): grapes are harvested riper, wineries use better clones, consumers drink more wines from warmer climates, such as southern Italy, the New World, etc, […]
During our spring wine tours we have visited the small and interesting Champagne house Philipponnat. On our visit in early May we saw people working in their prestigious vineyard Clos des Goisses with knapsack sprayers on their backs. Obviously they were doing some kind of treatment. It turned out to be weed control with a […]
When we visited Château Pichon-Baron, grand cru classé in Pauillac, recently we saw a small canister in the vineyard that we have never seen before. This canister is called CheckMate Puffer and is a new way of distribute pheromones that protect against the grape worm with the method with the curious name “sexual confusion”. The […]
Sulphur is something that is naturally present in our environment and it is a product that is allowed for all wine producers – organic as well as conventional – both to combat fungal diseases in the vineyard and as an antioxidant in the finished wine. However, there is a certain demand from organic producers for […]
Nine new grape varieties have been approved to be planted in the French vineyards. Five of them are old, almost extinct and forgotten grape varieties from the Southwest, from Gaillac, Fronton and other southwestern appellations: Bouysselet Blanc, Tardif, Verdanel Blanc, Gibert and Noual. The other four are so-called resistant grape varieties. These are new crosses […]
Flavescence dorée is a dreaded bacterial disease that spreads through a grasshopper. It was discovered for the first time in 1949. In France it is especially difficult in parts of the southern Rhône Valley and Provence. Here we can even see a decrease in the number of organic producers because it is mandatory in some […]
During the winter pruning many tons of vine branches, more specifically about two tons per hectare, are cut off the vines every winter in France. Sarments as it is called in French. In some regions it is a tradition to burn the branches, in others to leave them in the vineyard as a kind of […]
In late October, a conference called Tasting Climate Change was held in Canada. The subject was the impact of climate change on wine growing. An important question asked was: is it justifiable to plant vines where they have to be irrigated? Undoubtedly an interesting question. We asked ourselves approximately the same question when we wrote […]
