    I harvested this yeast from a starter I made. Obviously there is not as much yeast here as I wanted. When I go to reuse this in a 5 gallon < 1.060 batch I assume I'll have to step this up rather than make a traditional starter.

    For those of you with experience, is that correct?

    Yeah, it will likely need a couple of steps.

    What do you mean you harvested from a starter? Was it from bottle dregs?

    He made a starter a little larger than needed, pitched most of it in a batch of wort, but saved a little off for a future starter. I've been using this method for years and it works great. Much easier than washing/rinsing.

    Brulosopher has a nice write-up of the process:

    Yep this is what I did. Much easier, less messy.

    I do the same thing but I have to admit from the look of the picture does confuse me some.
    I have never had a separation of "stuff" like in the pic... Was there something else in the starter? other than yeast and malt that is... almost looks like some hop particles.
    I'm guessing that was the question eric was getting at.

    nope, nothing but yeast and wort. Could it be hot or cold break from boiling the wort? I chill pretty fast with ice water. I'm pretty sure I've seen that in all my starters.

    I was asking because it was such a small amount. I guess you should have saved more.

    Also because it's next to a bottle.

    The bottles were to hold it vertically until my tube rack arrives. I think it was so small because I didn't decant all the wort. And I was using a stainless baster to collect the sample. It barely reaches the bottom of my flask. Will have to find a better way next time.

    I'll second this one! I get these results pretty typically making a 1.5L starter. A pint gets poured into the sanitized mason jar for the next time I use the yeast strain. The remainder of the starter is either poured directly into the current batch or decanted off then poured into the wort. Lately I have been letting the starter sit after pouring off the next starter. Then I decant off what I don't need and pour the yeast directly into the wort. It works really well for many generations.
