Bottle oversize with the volume of 1.5 litres or the content of two normal bottles. A bottle of approximately this size was already created in France in the 17th century. It is considered to be ideal for a top wine, because here the bottle matures more slowly, which has a very positive effect on the quality. There is also a double magnum with a volume of 3 litres (4 bottles of 0.75 litres each), also known as Jeroboam. However, magnum and double magnum are not only available in the traditional bottle shapes, but also in the Bocksbeutel. See also under bottles and wine containers.
