Beer Guidance

Operations on beer: Other additions

Until beer is sold or supplied to the consumer, no substance that is likely to cause an increase in the duty liability may be added after the duty point without prior approval from HMRC. The legal basis for this is regulation 25 of the Beer Regulations 1993.

Detailed information on the addition of other substances to beer can be found in section 19 of Notice 226.
