Altenbourg has always been very special for the Sparr family. While not grand cru, Altenbourg is considered one of the best lieu-dits in Alsace. Charles' grandfather was the first to plant riesling here 60 years ago, a limestone soil, in the village of Kientzheim. Charles farms .6 hectare here today. Charles and Amelie have two Stockinger barrels in the cellar, one named after each of their children and in 2019, the Altenbourg was aged in one new Stockinger barrel. It was aged for 24 months in the barrel without any sulfur until bottling.
