Wine's world

Two studies have recently demonstrated a protective effect of wine compounds against coronavirus:

- American researchers discovered last January that polyphenols in grapes and wine prevent the virus from attaching to human cells (www.vitisphere.com/news-93204).

- More recently, the Taiwan Medical University found that tannins in wine inhibit two key enzymes of the virus, preventing it from entering cell tissue.

No hasty conclusion about the benefits of a hydro-alcoholic solution for internal use...

The Ministry of Agriculture [source Agreste] has published the quantity of plant protection products used per unit of surface area in vineyards in 2016.

Here are the results per wine-growing region (IFT = treatment indicator) :

- 21.50 IFT in Champagne, penalized by its chalky soil which retains moisture
- 18.00 IFT in Burgundy
- 16.40 IFT in Beaujolais
- 15.50 IFT in the Gers (Armagnac)
- 14.70 IFT in Charente (Cognac)
- 14.30 IFT in Bordeaux
- 13.60 IFT in Alsace
- 13.10 IFT in the Val de Loire
- 12.20 IFT in Dordogne

Then come the Mediterranean regions, favoured by their warmer, dryer and windier climate, less suitable for mildew and oïdium:
- 10.60 IFT in Languedoc
- 8.90 IFT in Provence and Southern Rhône (Châteauneuf du Pape)
- 7.60 IFT in Bouches du Rhône (Bandol)
- 6.90 IFT in Roussillon

Even if the year 2020 has not been favourable for the transfers/acquisitions of prestigious vineyards, two large Gironde estates have just changed hands this autumn:

- Ch. Siaurac (46 ha in Lalande de Pomerol), Le Prieuré (6 ha in Saint-Émilion) and Vray Croix de Gay (4 ha in Pomerol) had been acquired in 2014 by Artemis Domaines from MM. Pinault (Ch. Latour, Domaine d'Eugénie...). These three vineyards have just been sold to the bank and insurance company Arkéa-Crédit Mutuel. As this is surely a much longer-term investment and they have been successful in Calon-Ségur since 2012, we intend to follow their progress closely and will not fail to speak to you about it again.

Ch. Beauséjour-Duffau-Lagarosse- , Saint-Émilion's 1er grand cru classé (vineyard unchanged since 1847), a 7 ha jewel at the top of the limestone hillside, wedged between Angelus and Canon, is being acquired by another neighbour: Clos Fourtet. Already much sought-after, we are confident that Beauséjour has every chance of quickly becoming one of the most attractive crus in the Gironde vineyard, given the quality of the work carried out by Mr Cuvelier and his team on all their properties (Clos Fourtet, Grandes Murailles, Côte de Baleau and Poujeaux). Moreover, their pricing policy has always been very reasonable.
