Yeast froze, new plan for wlp545

[d3track]

Well crap - had two jars of wlp545 that froze overnight, so I'm guessing they are toast.

I have a 1.078 & 1.094 batches I was going to use the washed yeast for. Since it's a Belgian strain, do you think I could wash the yeast from 1.078 batch? I couldn't find much info on if Belgian strains can be resued from higher gravity batches or if I'm know looking at spending big on yeast for these batches.

as in jars like jars of yeast you harvested ? I have had yeast freeze and just warmed up and use it

make a starter and you will know if it is good or not

all the best

Yeah harvested yeast. Maybe I will make a small starter and try then, at least I didn't throw them out yet.

Should I make a lower gravity starter and step up?

I start at 1.040 with mine

Freezing the yeast is not the end of it all. Calculate a 10% loss in viability for each freeze/thaw cycle.

The strain doesn't matter. You can reuse yeast from a 1.078 batch. It's not considered optimal because the yeast has "been through" more, but it's fine.

It's on the stirplate now, I'll try to remember to snap a pic in the morning to see if I was able to salvage it.

Not quit 24 hours in, it's going....

Should I get the sulfur smell from the starter? I don't think the first time I used this yeast the starter smelled, but the 5 gallon fermentation did...

It happens, probably from stress. Usually I associate strong sulfur with fermenting ales under 60F, but maybe the freezing played some part in that. Seems like it's taking off, though.
