Jacquère is arguably the most important white wine grape varietal of the Savoie wine region in eastern France. It's exact heritage and first reference and use of the name Jacquère was around 1868 by the French ampelographer Pierre Tochon, when describing vineyards and vines in the hilly region known as Abimes de Myans.
DNA analysis is still working on parentage, but current research suggests Jacquère is one of the many offspring of Gouais Blanc. The other is unknown, though thought to be of French origin. The varietal is generally very productive, though early budding in marginal climates can be an issue, it ripens mid-to-late in the season, and gives best results when the vine canopy is well pruned. The varietal seems to thrive in clay-limestone and rocky soil types.

 

Jacquère is a high-yielding grape varietal, typically used to produce lightly scented, dry style white wines, such as Vin de Savoie. Jacquère is the grape used in Apremont wines, and is the wine usually paired with cheese fondue (a dish from the region) - along with being found in Bugey wines.
Furthermore, Jacquère has been grown in some Condrieu vineyards, but it is officially not allowed to be used in Condrieu Appellation d'Origine Protégée AOP wine. After some increased plantings in the 1980's and early 90's, it has remained at a constant area of around 1000 hectares (as of 2012) across France.
In the Savoie wine region - it typically produces wines at their best when enjoyed in their youth. Vines in Savoie are often planted on mountain slopes, with altitudes ranging between 250m - 550m. Despite their elevation, Savoie vineyards enjoy a surprisingly warm microclimate due to the southern sun exposure and the moderating effects of nearby rivers and lakes.
The classic appellations for Jacquère are; Apremont, Abymes and Chignin - but you can find many Blanc de Savoie based on it in other places, such as the beautiful Coutaz.
Also in the Savoie region - Jacquère is the most widely planted grape varietal, accounting for just over 50% of all the plantings. The wines flavours range from floral (white flowers) and fruity (pear, white peach, grapefruit) to mineral and flinty. The wines have a natural high level of refreshing acidity which results in bright citrus fruit characters in the wines. This natural character makes for a good wine pairing with seafood, and, even though most people drink them when skiing in the winter, they are an ideal choice during summer. Jacquère is usually and best enjoyed young, while it still displays its clean minerality and lively citrus personality - enjoy.
