The present invention is particularly useful in producing a sulfur dioxide-enriched gas from gases relatively weak in sulfur dioxide content.

a sulphur dioxide content of not more than 10 milligrams per kilogram of total sugars

a sulphur dioxide content of not more than 25 milligrams per kilogram of total sugars

a sulphur dioxide content of not more than 25 milligrams per kilogram of total sugars

a sulphur dioxide content of not more than 25 milligrams per kilogram of total sugars

a sulphur dioxide content of not more than 10 milligrams per kilogram of total sugars

The maximum sulphur dioxide contents of wines are given in Annex I B.

non-Saccharomyces yeasts, to reduce the content of sulphur dioxide;

The corrosion process is mainly influenced by the sulphur dioxide content in the atmosphere and, as this has drastically declined, erosion has also been sharply reduced.

A maximum sulphur dioxide content of 400 milligrams per litre should be authorised for these wines.

The maximum sulphur dioxide contents of wines are given in Annex I B.

In order to ensure the preservation of these wines, Italy and Hungary have requested a derogation from the maximum limit on sulphur dioxide content.

wine produced in Spain before 1 September 1986, the total sulphur dioxide content of which does not exceed the maximum laid down by the Spanish provisions in force before that date, and

wine produced in Portugal before 1 January 1991, the total sulphur dioxide content of which does not exceed the maximum laid down by the Portuguese provisions in force before that date.
