Before being bottled, it’s necessary to undertake a last organoleptic and analytical characteristic check of the wine by tasting and a final test. Depending on the results, it’s possible that a fining agent s added or a final filtering is undertaken. Bottling generally requires a sterilising filtration carried out on plates or membranes.
Bottling requires using perfectly clean equipment and respecting very rigorous hygiene conditions.
Bottling was made obligatory in the Alsace wine production areas by a law dating from 1972. In addition, all still wines have to be bottled in Flutes of Alsace bottles.
