Regulation and Legislation

In order to ensure that you meet your legal and Quality obligations it is essential that routine tests are carried out to ensure that you can demonstrate ‘Due Diligence’.

Customs and Excise require all beer to have the alcohol calculated, but the calculation should be checked a minimum of once per year to confirm consistency with calculated results’.

This should be done by distillation.

Sulphur Dioxide should be checked to ensure that legal limits are not exceeded.

The UK limits for Cask conditioned beer are 50ppm and 20ppm for Keg beer. Wine and Cider also have legal limits.

Sulphur Dioxide level above 10ppm should be labelled (in small pack) under the allergen labeling regulations.

There are several Food Regulations that are pertinent to Beer:

Food Safety Act 1990 – this states that food (including alcoholic beverages)...must be of the nature, substance or quality expected by the consumer AND that the business must prove they took all reasonable precautions and exercised Due Diligence.

As part of the requirements of the Food Safety Act and subsequent Regulations (Food Hygiene Regulations – EU 852/2004 and UK SI2006/14) a HACCP Plan is required to be  undertaken and controls put in place to ensure that HACCP Critical Control Points (CCP’s) are being monitored.
