The plot thickens even further… I got a delivery of yeast, and here’s how they look. My observations and thoughts below. I thought I would confirm some hypotheses but instead I am even more confused.
- M76 is consistent with M84 + Diamond. Diamond has two types of grains shapes. These are also present in BRY-97, so I wouldn’t take it as an indication of a mix.
- Brewferm Lager seems different than M84, which is supposedly Mauribrew Lager 479. If anything it looks like Nottingham, which would actually be a plausible option.
- Nottingham doesn’t really look like M42 at all. Maybe they have different factories with different shapes (although all my Lallemand is listed as products of Austria)?
- M44 is consistent with BRY-97, although they have different color that might be due to being from different batches.
- M15 and Windsor don’t really look the same either. M15 has the same look as BRY-97, M42 and Diamond though so might be another batch/machine for the Windsor?
- M36 gives no indication of being a mix at all and doesn’t look anything like M15 or M42.
Some pairings that could plausibly be considered are:
- Mauribrew Draught for M42? Matches roughly for attenuation, recommended temperature range and flocculation.
- S-04 for M36?
Now I have some beer to brew with all these yeasts…
