If I were selling yeast I could make more money selling an extra pack than having the brewer make a starter.And yet ....
- Both Fermentis and Lallemand, In 2020 and 2021, posted videos that include discussion on making a starter with active dry yeast. (I haven't followed their videos since then).
- Lallemand has a "best practice" document at their web site on on making a starter with Diamond Lager.
