HBT Beer Guru Yeast Rinsing Check

[TexasTea]

Hi All,

I tried my hand at yeast rinsing. I discarded the top layer (beer) some of which resettled out, kept the middle layer (creamy white yeast) which I poured into a sterilized and cooled jar and discarded the bottom trub layer (darker brown like peanut butter). I will use this in less than a week.

This is what I have left. I see a few darker spots (trub). Does this look OK to ya'all yeast rinsing beer guru's out there?. Yeast is Lutra BTW.

looks fine prolly is. but why wash just throw the whole enchilada in there it works just as well with less risk of infection and oxidation. IMO

I was going back and forth thinking about doing that. I didn't because I usually throw the yeast on top (I do ales).I have one of those cheap chinese conical 8 gallon fermenters (which work well BTW). I figured I'd leave the first 2 or 3 batches until the trub/yeast gets up near the port, then rinse. So I'd cut my rinsing (and threat of infection) down by quite a bit. Thanks fluketamer, I'm trying that next time.

I don't know how long this yeast washing fraud thing is going to live on, but just for the record, you cannot wash yeast at home.

i love pouring apple juice on old yeast cake to make quick cider. it always works well. in that vein i have since started using 1 pack of yeast for every two beers by just pouring new wort onto yeast cake. the second run always ferments much quciker with much less lag but ususally takes a little longer to clear. it would prolly work just as well for three batches but at 4-5 dollars for dry yeast its cheap enough .


i like the fact that i only have to clean fermentor once per every two beers. it saves me some time and effort. a fresh cake especially if from a closed transfer is essentially antibacterial with just yeast in there. i usually like to use it within a day or two. i have had bad experiecne with old (couple of weeks) repitched yeast ..... obviously no yeast rinsing involved.

Yep, that's why I call it yeast "rinsing". You can rinse it at home. I may even try redrying some to make Ri-Re (Rinsed-Redried) yeast to see if I can keep it around longer.

You do not accomplish anything by that. You neither separate dead cells from alive cells nor do you remove trub or other unwanted things. What you do remove, is yeasts natural barrier, which is beer.

Sounds harder than I mean it, but a little knowledge about microbiology goes a long way here. It is just not as easy as many youtubers make it look like. There is something like an acid wash, but that is far more complicated, and if done wrong, you basically kill your yeast.

Best way to seperate dead from alive cells is to take a small portion of the sludge and use a multi step starter to increase the numbers. That way the living cells quickly outnumber the dead ones.

Wait, are you saying you don't routinely do density gradient centrifugation in your basement?
