I don't worry about infection since I cool the wort while the lid is on and my lagers are chilled below 50 *F anyway which makes it very unlikely for an infection to take hold.

Is that where you are getting your DMS?
I don't like that your wort is sitting covered like that. I think DMS can still "form" at that stage.

Re: the topic, without having read the thesis, what does this do for head retention?

No effect on head retention, IIRC, some of the test samples actually had better retention than the control but, it's been a while since I read it and there is a lot of info to discern.

No, I whirlpool cold. DMS only forms at higher temperatures. I would be concerned if I do a hot whirlpool.

only 35 pages for a masters thesis and basically one experiment...ugh, I think I made a mistake with the Ph.D.

Apparently there is no negative effect on head retention. The amount of oil is very small and it mostly gets assimilated by the yeast. The remainder probably either floats on the surface (and doesn't get racked) or sticks to the walls of the fermenter.

Is it finished now? Or are you still in the tedious stages of final writing (hence your comment)? If it is done, congrats!
