DIY Beer Brew Cans - Yeast Details

Recommended Posts


Yeast Strain/s are denoted by the R Product Code on the back of the sachet, beneath the Julian Date Code. The Julian Date Code is the packaged date and is a five-digit format counting the number of days into the year, e.g. for yeast packaged on the 11th of March 2020 = 70th day of 2020, it will display as 07020.


  • C – R007 = Coopers ale yeast. Our own strain, which was developed in-house, but it is not the same strain as the yeast in our commercial ales.

  • C+L – R3426 = A blend of our Coopers ale yeast and a lager strain.

  • A – R3554/R3555/R3557/R3559 = various ale yeasts*

  • L – R3422/R3556 = various lager yeasts*

  • W – R3558 = wheat yeast*

These strains are commercially available dry yeasts and their details are held in confidence. Listed below against each brewing extract, we’ve detailed the yeast type, then the R Product Code, followed by an example Julian Date Code in brackets.
