Ever seen WLP001 clump like this?

[RiverCityBrewer]

I went to harvest some yeast from my conical and this is what it looked like


Now I have used this yeast quite a bit and never seen it clump like this before... I still intend on using it for the next batch (3rd generation of this pitch). Just curious if anyone else has seen it act like this before.

I've got some PacMan doing exactly the same.

I saw that only once in WLP001- coming right out of the vial. I was a little concerned, as that's not been my experience with that yeast, but it was fine. The next time I bought WLP001 (about 10 days ago), no clumping at all.

I know some English strains look like cottage cheese, but I had never seen it with WLP001 except for that one time.

What temp do you have it at?


I've seen 001 do that after a couple generations of 60F-62F fermentations... I think I was just selecting higher floc mutants....

It's a second generation that has been at 68 for both ferments... I didn't think about mutation, I may not use it for a 3rd generation after all.
