It’s all in the name… Schlumberger could be one of the most used names for wineries ever. From Alsace to California and from Baden Germany to Niederosterreich, Austria. The famous family (if we name them all as a family) is all over the world producing their wines. By far the biggest and most prestigious winery is located in Austria. They’re well known because of their ability to make outstanding sparkling wines. In fact, they exclusively produce sparkling wines.
