Have you seen this type of clumping with this particular strain WLP001? I haven't, that's why I thought it was abnormal. But, I don't really have enough experience to say what's normal.
I'm wondering if perhaps I selected a more highly flocculant variant of that strain when I used the last bit of yeast in the vial to build up the starter. I pitched the majority of a starter to a different wort, then used the little bit that was left to build this starter.
