Mangrove Jack dry yeast experiences

Hey everyone, I’m looking for anyone with experience with Mangrove Jacks dry yeast, specifically California common M54. I made a starter to harvest some yeast to use again for my next brew session. Pitched at 68F about 12 hours ago. I see no activity at all, not even yeast floating. I’m wondering if this is typically for this strain? Using a pitch rate calculator, I should have 200 billion extra cells, so I don’t think that’s the problem. Any experience would be greatly appreciated. Cheers :beer:

Nothing on M54, but search the forum, and you’ll get some general information about MJ yeasts. I was interested too. I haven’t used any yet, but I get the impression they are slow starters and may not always attenuate well. Please keep us posted on your experience. I’d sure be interested.
