Question about reusing yeast from blow off.
« on: October 18, 2014, 12:45:00 pm »
Hi all. My 2.5 gallon batches in a 3 gallon carboy always need a blow off and I lose alot of good yeast in the process. I made a sanitized yeast blow off/collection apparatus that I saw in the Yeast book. I collected a lot of good yeast but I was wondering. I ran the blow off for the first week of primary. I read something about not using the first bit of the krausen owing to proteins. Should I give it a shake and let the protein settle then decant off a cleaner yeast sample or is it not enough protein material to be of any concern?

Thanks!

When I harvest yeast (post-primary - I haven't top-cropped anything yet), I keep everything - trub and all. I'm of the mind that there's really no need to much around with your harvested yeast slurry. By the time it gets diluted into a new batch that little bit of trub, protein, etc isn't going to be noticed. Heck, the protein may even act as a yeast nutrient.
