Manseng Gros Blanc, is a green grape from France, most commonly known under the name Gros Manseng.

Characteristics
Manseng Gros Blanc is a thick-skinned variety, also known to be quite tough. More im­por­tant­ly though is the fact that it can con­tain both high levels of sugar as well as aci­di­ty. Fla­vour wise you can expect to find both flo­ral and frui­ty tones, spi­ci­ness and a touch of tro­pi­ca­li­ty. Depending on which kind of wine (e.g. as sweet or dry) you will find more or less of acidity.

Wines
If you buy a white wine from Jurançon, it is quite likely that it contains Manseng Gros Blanc. It is often blended with, and is increasingly playing “second fiddle” to its relative Petit Manseng. Traditionally Manseng Gros Blanc has been used for producing sweet wines but nowadays dry wines are easy to find on the market. You can then expect to find a rather crisp wine in the glass. The dry varietal Manseng Gros Blanc wines tend however to be viewed as of less importance compared to the ones of Petit Manseng.

Food pairing
A grilled chicken dish with a fresh salad will be an excellent paring with a dry Manseng Gros Blanc varietal wine. Best served at 8-10°C/46-50°F.

Where is it grown?
Manseng Gros Blanc is almost exclusively grown in France, and above all in the country’s south-west part.

Within the geographical areas of Gers and Pyrenees-Atlantiques over ninety percent of the planted area can be found.

The grape’s heartland is in the area west of Toulouse, in Côtes de Gascogne and a bit further south-west in Jurançon. Its acreage has increased from 2.160 ha/5,337 ac to 2.959 ha/7,312 ac in ten years. The increase has taken place in the Gers region.

Outside of France, there’s a tiny (experimental?) planting reported from Brazil.

History
As so often is the case, the grape is thought to be indigenous to the area where it now has its heartland, e.g. in the southwest of France, most likely in Jurançon. It has been established to be related to another Manseng grape, Petit Manseng. It is however not yet clear in which way.
