100% Jacquère. The vineyards are all on south and south-east facing slopes with stony, limestone clay soils. The vines average 25 years of age. The Jacquère variety is picked by hand at the end of harvest period, when it attains merely 10 to 11 degrees of alcohol. At picking, theJacquère is fully ripe and packed with flavor while remaining delicate and fresh with a low sugar/alcohol level. Eric Carrel uses a pneumatic press to gently extract flavor and aromas, and he ferments in stainless steel tanks at lower temperatures for one month. Malolactic fermentation is blocked and a small amount of the wine’s natural CO2 remains to further enhance its freshness and vitality. The Jongieux Blanc is aged in tank on its fine lees. Bottling takes place in January, after the wine is stabilized in the naturally cold Alpine ambiance. Domaine de la Rosière produces about 1000 cases annually.
About the Producer
Domaine de la Rosière is located in the village of Jongieux, in Massif de la Charvaz mountains at the beginning of the French Alps. It is situated about 40 miles southwest of Geneva, in between the Rhône River (near its start) and Lake Bourget, France’s largest lake.
The estate dates back to the late 19th century and was expanded to its present size in the 1970s and 80s. Eric Carrel and his father François, now retired, cultivate 13.5 hectares of vines in the Jongieux and Marestel appellations. 100% of the production is estate-bottled. Farming practices: sustainable. All of the vineyards have grass planted between the rows to reduce yields and create a healthy natural ambiance, and only organic fertilizer is used.
The Jongieux vineyards are very steep, southwest- facing slopes created by ancient glaciers. The altitude is between 400 and 500 meters, yet the microclimate is very warm. The privileged clay-limestone slopes of the Jongieux appellation allow the grapes to ripen more fully than in any other Savoy regions, due to 2-3 hours more sun daily. As a result, the wines are not only fuller, but also more balanced and fresher, because there is far less need for chaptalization. Indeed, the regions’ top Cru, Marestel, is located in Jongieux.
