When you've noted that with kefir, does it clear up as the ferment progresses? As my krausen developed, the chunkiness went away.

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.

I don't use WL yeast since my LHBS doesn't carry it, but it's basically the same yeast as Wyeast American Ale 1056 and Safale US-05. I've seen clumping like that with both of these strains.

Oh and name it if you can.

Lactobacillus

Kind of a "taboo" topic on here. Some time back I hunted the web for pix of infected brews, but the thread was killed. Here are the pix.

I don't know why I open up threads like this. All it does is make me worry about my next batch. Of course it could also make me continue to be obsessively anal about my sanitation procedures.

The worst kind of infection is the one that isn't so obvious. I had one recently that I didn't catch before it was kegged and carbonated. The carbonation breathed life into it.

So pour that hydro sample into a wine glass, swish it around and breath it in. It can be much more subtle when flat.

What's the most common reason for an infection?
