Situated on a hillside facing east at an altitude between 240 to 350 metres. The soil is quite varied with a sublayer of granite and chalk, but all has brown top soils with a strong concentration of calcium and magnesium that gives it typicity. The first mention of Kaefferkopf was in 1338 in the cadastre of the Abbaye de Pairis in Ammerschwihr. It has only recently gained its Alsace Grand Cru status, being the 51st vineyard to be accorded that honour.
The wines from Kaefferkopf are produced either from a single grape variety ( Gewurztraminer, Pinot Gros and Riesling ) or from a blend of all three varieties in strictly defined proportions.
Grand Cru Mambourg
Mambourg at Sigolsheim first mentioned in 783 for the quality and power of its wines. It is one of the earliest ripening sites in Alsace with excellent exposure to the sun. Calci-magnesique soil overlays outcrops of chalk and clay.
It is the Grand Cru for a special expression of Gewurztraminer, combining elegance with longevity on the palate.
Grand Cru Florimont
Between Ingersheim and Katzenthal
This Grand Cru is situated on south and east facing slopes of the lower hills of the Vosges. The soil is mainly marn and chalky, relatively stony. Thanks to the protection afforded by the Vosges mountains, the rainfalll is very slight. Gewurztraminer is the King of grape varieties here and it gives wines of great length.
Florimont, the favourite of the Baron de Schwendi, a great supporter of Alsace viticulture, is one of the stars of the Cave Jean Geiler.
Grand Cru Sommerberg
Between Niedermorschwihr and Katzenthal
It is at the foot of the Trois-Epis on a steep slope at 400 metres with an orientation to the south. The granite is in the form of volcanic rock composed mainly of quartz crystal and micas, which have broken down to form a layer of heavy sand entitled granitic sand.
The site produces wines of great vivacity with a character more floral than fruity ; Riesling is especially successful.
Grand Cru Brand
At the entrance to the valley of Munster, this «fire earth» benefits from maximum sunshine at an altitude of 380 metres. Situated on a sub-strata of granite, it offers a sandy topsoil. The granite is particularly relevant for Riesling and Pinot Gris, to which it confers finesse, subtility and enhanced fruit definition.
