Have a question about the legal sulfite content in beer. So far this is as I found on your site, 10 ppm. If higher, it must be stated on the eticket. Now I have heard that the legal standard of sulphite content in beer would have been changed to 15 ppm. Without having to mention this on the label. Would it be possible to confirm if it was changed from 10 to 15 ppm.
Thanks in advance,
Els
Answer
Dear Els,
In my opinion there is no change in the permitted amount of sulphite in beer. Sulfite in beer comes from the yeast during fermentation. The yeast absorbs sulphate from the malt extract and converts it to sulfite. Beers up to about 6% alcohol must contain less than 10 ppm. In stronger beers this is less than 20 ppm.
Kind regards,
