Sweden says yes to the sale of wine from winemakers

Swedish wine producers had every reason to celebrate Sweden’s national holiday on June 6th.
The Swedish wine tasting began on Monday, and two days later the government opened the long-awaited farm sales.

First things first: after years of research, the Swedish government has put forward a watertight proposal to allow farm sales - that is, allowing winemakers to sell their wines to visitors. Sweden has had an alcohol monopoly since 1955, and the issue has always been controversial, but with the increasing number of commercial winemakers and growing interest in domestic wine, the government has now put forward a third proposal that could become a reality in spring 2025.

PIWIS – How the vineyards of the individual varieties have developed.

In Germany, a total of 1,135 hectares were planted with the top 10 white PIWI grape varieties and 1,790 hectares with the top 10 red PIWI grape varieties in 2022. This makes a total area of 2,925 hectares of the top 10 white and red varieties and corresponds to a share of 2.8 percent of the total German vineyard area of 103,391 hectares in 2022.

2 PSM treatments are sufficient even in case of high disease pressure in Muscaris and Souvignier gris

«The Grangeneuve organic winery in the Dordogne is managed by the department's Chamber of Agriculture as part of the Dephy network.

In 2018, winemaker and owner Anthony Castaing planted the first resistant grape varieties: Muscaris and Souvignier gris.

In the last two vintages, 2022 and 2023, two copper and sulphur-based treatments were carried out on these vineyards. His overall indicator for the frequency of plant protection treatments is 1.56. "This is a great advance in plant protection and a reduction in workload, even in years with strong downy mildew pressure like 2023," he notes.

On the other hand, "it is no longer possible to go on holiday in the last two weeks of August". In 2022, for example, the Souvignier Gris was harvested on August 24, well ahead of the Sauvignon gris, the reference grape variety in the monitoring carried out by the CA24.

This "marked advancement of the phenological stages begins as soon as bud break occurs," says consultant Camille Delamotte during a webinar on the subject. In 2022 and 2023, Muscaris and Souvignier gris were in the "green point" or "leaf break" stage at the end of March. In 2022, the vines were affected by a spring frost on April 1. "This risk must be taken into account. These varieties are recommended for terroirs with little or no frost."

First feedback on the resistant variety Souvignier gris

First feedback on the resistant variety Souvignier gris

Its berries are pink, which is not very common among the most widely grown grape varieties in France. However, its greatest peculiarity is that it is resistant to powdery mildew and downy mildew. It has inherited this resistance from one of its relatives, the Bronner (the other is Cabernet Sauvignon). It is called Souvignier gris, one of the resistant varieties currently authorized in France.

The IFV can confirm that the Souvignier gris has at least one resistance gene against powdery mildew: Ren 3.

PIWIS 2023 – Another tough testing year!

Haidegger Perspectives Department 10 – Agriculture and Forestry

We believed that the growing year 2023, with its strong infection conditions for vine downy mildew, would remain an exceptional year. But 2023 taught us otherwise.
Ing. Wolfgang Renner

The past growing season has shown that robust "classics" such as Bronner, Muscaris, Solaris and, to a lesser extent, Souvignier gris can be relied upon. These developed optimally despite adverse weather conditions. New varieties that have been particularly notable for their good resistance to downy mildew in their first years of growth also give hope, such as Sauvitage or Voltis.
