So, I've had a really, really, really vigorous fermentation (you could use the blowoff tube as a pressure washer ffs) with some WLP 530 making a tripel. I was marveling at it when I looked into my blow-off vessel and saw a sizeable yeast cake that LOOKS alive. It's very, very white.

However, I have heard that Star san is a fungicide. But don't yeast like acid? If my star san solution is lower than effective pH, could I use this yeast to kick a starter up for a patersbier?

Prost!

Make a starter with it and try it out! Be prepared for it to fail if the are dead but at least it will be in a few cups of extract instead of a whole batch!










....or just wash the viable yeast in the primary when its done.

I'll be doing both, but I have 2 empty carboys and 9 lbs of Belgian pilsner just kinda sittin' there....

I've got the itch-- you know?

If it were lower than effective PH, it would still be effective. In fact, more effective. I think you mean higher than effective.

IMO, don't re-use the yeast. It's incredibly easy to make a starter with healthy yeast, no need to take risks. EDIT: You'll have a HUGE amount of yeast ready for washing when the beer is done fermenting!

Sounds like an awesome ferment! The powerwasher effect is always marvelous to see!

I'll make a light starter for it and see if there's any activity...

FOR SCIENCE!

I like the way you think!

My philosphy is fvck it, let it rip!

Even if something funky is in there, it might compliment the belgian yeast.

Or not but there is only one way to find out!

Yea, might as well. A starter never hurts. A healthy one that is...

We've all seen dead yeast. It has the color of dirt.

This yeast looks like a fine white sand. It's... beautiful!

If there is living yeast in a container full of star-san, I will never buy star-san again. It's a sanitizer! It should kill living things. Makes no sense that the yeast would be alive.
