I oil my starters for 10 min.
It took me a second before I realized it was a typo. At first I thought it was some new technique with which I wasn't aware.
I add the Wyeast powdered nutrient in starters and Servomyces in the boil for most batches. I'm wondering if I really need to use Servomyces or if I can just use the less expensive powdered nutrient instead. I'm not sure what the differences are. I once used them hit and miss. Now I use them all the time. Nutrients do seem to help quite a bit.
I am pretty sure it was a typo but there is a technique, not much held by homebrewers anymore as far as I know, that involves putting olive oil in the starter to provide the yeast with lipids. This allows you to lessen or even skip the aieration step and supposedly increases shelf life. I beleive some large scale pro brewers do use this as it closes up a quality loss door in long term storage/transporation.
