do i need to decant a 2L yeast starter?

To Denny: I was just backing up what you stated as the "Science" of your method was being questioned

To theDeutcher: This thread has taken a few crazy turns for sure and I agree things are getting a little picky, as I stated earlier, my opinion is that there really is no eight or wrong,in this hobby, it's completely up to the individual brewer and what works best for their system/setup/process, but hence, even that was questioned as well..............sigh.....

I do the same thing as Denny, and for the same reason... warming up the yeast only makes it use up its glycogen reserves.

Thanks, duboman...I realize that and my reply wasn't directed to you. emjay, glad to hear it works for you, too. I'm surprised by the resistance to even trying it.

It'd just add that some yeast strains are more flocculant than others and decanting them after only a day in the refrigerator will toss out the more flocculent cells that give you the best attenuation.

A yeast like WLP007 is very flocculant and most of the cells will clump up on the bottom of the flask after a day but a yeast like Wyeast 1007 is less flocculent and may need 3-4 days to settle out.

Don't you mean you'll toss out the less flocculant cellls? The more flocculant cells will be at the bottom of the flask much sooner than the less flocculant cells.

I'm using strains rated at least high in flocculation, so it's really no issue for me. I often do leave an extra day at the end of the starter schedule in order to factor in settling variables. Normally I don't need that extra time though.
