I just racked to keg with a steam clone I made a few weeks ago. I am getting ready to make another one. The beer was obviously flat, but no off flavors and pretty tasty. Should I use the smack pack and underpitch (as I have recently learned) or just get a scoopfull of the yeast on the bottom of the bucket and pitch that? How about both? the one in the bucket is white labs, and the yeast that came with the ingredents for tonights batch is wyeast. both are thier California common yeast

with tonights runnings, I am going to reserve some for making a starter on the next batch, but that doesn't help me out tonight.

I've always been a reuser of yeast. Why not just use the whole yeast cake on your new batch though? That's pretty standard practice and assures a nice, fast, vigorous fermentation.

what are you trying to do here? i see allot of questions and no explanation of what your trying to do.

Would you want a fast, vigorous fermentation with a california common? While that's not a favorite style of mine, I was under the impression that you would want the esters produced during yeast reproduction. Wouldn't using the whole yeast cake make the beer turn out a bit more clean?

I would look into yeast washing. Here's a helpful link to that process.

thats a good write up, I will try that next time.
Unfornately this time I racked into the keg, poured off the top layer of crud, then scooped up just over a cups worth of yeast with a sanitized measureing cup. I then covered it with sanitized saran wrap and stuck it in the fridge. I haven't popped the smack pack yet, but I can still do it if I need to.

This would be the previous batch


As in another Steam Clone

I have learned here that using one smack pack is underpitching yeast, I am just trying trying to find out if it is worth the effort to use some of the yeast from the previous batch, or if I should just use the smack pack.

I don't know if there would be any advantage to using both yeasts. they are similar strains but different brands.


I realize how this post looks, I am not trying to be an arse. I ramble quite a bit and this post is trying to clarify as much as I can.

i would definitely use some of the yeast from the previous batch. i probably wouldn't use all of it though, that will be overpitching, which isn't all bad, but if you use ~1/2 of it (see mr. malty pitch rate calculator for exact mL of yeast to collect), that should be plenty. from what i've experienced and heard, yeast will progressively produce better beers if you use the same batch.

Another vote for repitching. For an average gravity beer I'll pitch from 50-100ml (per 5 gallons of wort) of slurry depending on if it's an ale or lager.
