Planted in 1972 on marl-limestone soil, the vineyard for this AOC Alsace Riesling is located in Molsheim, at an altitude of 250 meters. The yield is 40 hectoliters per hectare.

The Alsace Riesling grapes harvested on October 16, 2021, were directly placed in 228-liter barrels as whole clusters upon arrival at the winery. They then underwent a 6-month maceration without extraction. Afterward, they were pressed using a vertical manual press. They were then placed in stainless steel tanks for an additional 8 months. Throughout the aging process, we frequently tasted the wines. They were subsequently stabilized and filtered before bottling. No sulfites were added during vinification, only before bottling. The two cuvées of Riesling were named after Pierre-Alexandre's daughter, Ysée, who was born in 2021.

After a chance meeting at a dinner party nearly 10 years ago Alexandre Aires and Pierre-Alexandre Soltana became great friends and after years working in similar roles they decided in 2018 to start their project Maison A&S. Pierre-Alexandre has worked for Comtes Lafon for more than 10 years. Alexandre has worked for 8 years for Domaine De Bellene where he performs all the cellar work. Maison A & S philosophy is to work in harmony with nature to get the best fruit under the most perfect conditions, to make the best wine to bring people together and share about it and always try to make it better. For now they buy their grapes from organic producers who are also their friends but are in the process of beginning a lease for the 2022 growing season. In the cellar they make no additions other than small amounts of sulphur.
