That's a good question....I pmed my Harvesting Guru Prof Frink a link to this post, so he can answer for us both....So my propagation went pretty well I kept feeding for around a week and got a fairly good layer of yeast at the bottom of my 1 gal glass jar. The cool thing is that the yeast chugged away on around 1/2 gal of wort for like a week!! I'm making a 10gal batch of Edwort's pale this weekend and I think I'll try 5 gal with the Pacman and 5 gal with the Notty and see what the taste differences are. Revvy am I ok making starters with the vials I have collected? I'm worried about getting too many generations along and having bad mutations.
It looks like you made a starter of about 1/2 gallon of wort, right? You will be fine pitching that, you have nothing to worry about too many generations. The amount you need to use yeast before getting any mutations is typically beyond what most homebrewers need to worry about. I posted some numbers in another thread recently:So my propagation went pretty well I kept feeding for around a week and got a fairly good layer of yeast at the bottom of my 1 gal glass jar.

Starsan actually helps yeast. It works as yeast food...I have not had any luck. I took a gravity reading this morning, and there has not been any fermentation on the starter. I have pitched the yeast from the bottle of 2 different Rogue bombers.
I did learn something though. I must have boiled too much water off. The reading was 1.080. I added some filtered water today to give them a chance to start with a snack. The layer on the bottom of my 1/2 gallon jar is from the malt extract.
Could starsan or PBW kill the yeast? This jar was boiled for yeast harvesting and it does not look right now. The boiling water was softened, so I think it left some residue that I cannot get to come off. I cleaned it with PBW and starsan. If this does not work, I will have to just order some. I hate it, I planned on getting the yeast from some other bottle conditioned beers

I have never, ever, heard of malt extract falling out of suspension in any wort, ever....If you boiled it with water it mixed in.
Take a picture of it will you? If it looks even slightly like this (Not mine)
Even if the line is only as thick as a fingernail...you got yeast.
I still believe you got viable yeast, despite what your hydro is telling you...I still think you should give it another feeding of wort.
How many times do I have to say it?Any tips? I am almost to the point where I think I should dump out the wort and pitch totally new wort on top of the yeast. My worry, is that I have not seen any action yet and I will pitch it and will ruin a batch of beer or at the very least delay fermentation.
Does dead yeast look different?
Thanks. There are a few on there that are not bottle conditioned now like Fat Tire. I may start a spreadsheet with what I learn as I purchase some beer. I plan to get a mixed six pack with some different bottle conditioned beers.
We have krausen today. I think the first batch i pitched was dead. It may have been shocked a little. Today, the thing is fermenting and boy does it smell like beer. I plan to wait to brew another week and step it up a couple of times before I pitch it.
Made a starter from one of the slants I made a couple of weeks back and got a good krausen within 12 hours, it's still happily chugging away. I can't wait to pitch it in the batch, I'm thinking it will really take off.
You know I had sort of citrusy smell when I was propagating but I assumed that was due to old beer, don't really have that smell now in my starter but I will say that Pacman does have a distinct smell I've noticed it in Rogues beers and now in the Pacman starter, it is unique to what I have experienced with most ale yeasts. I really like the character of this yeast if I have success with in in this batch I just may use it as a house yeast, rather buy a bottle of Rogue every once in a while and drink it instead of paying $6 for a vial of yeast.What does it smell like? Mine has a unique smell. Not sure how to describe it. citrusy?
