Prevent the formation of Diacetyl with a few drops of ALDC.


ALDC is an enzyme that causes the direct decarboxylation of alpha acetolactate to acetoin, thus avoiding the production of Diacetyl and reducing maturation time. ALDC is produced from a submerged culture of Bacillus subtilis.


  • Reduces Diacetyl production
  • Significantly reduces maturation times
  • More efficient vessel utilisation
  • Increases production capacity
  • Reduces energy usage
  • Improves beer quality

Guidelines for use

  • Check that the product is within its shelf life before use
  • Read the Safety Data Sheet prior to use
  • Care should be taken to avoid unnecessary skin contact during handling
