Yeast Amount

I’m brewing a breakfast stout on Monday and plan to pitch WY 1084 yeast that I harvested off a prior batch. This will be my first time using harvested yeast.

I just swirled up the cake with the last 1/4 inch or so of beer in my fermenter and poured it into 2 quart mason jars. I rinsed them by allowing them to settle, poured off the beer, added boiled/cooled water, swirled good, allowed to settle then poured off the top ‘clean yeast’ into one quart jar. It was almost a full quart that has now settled into a nice light colored cake of yeast and clear amber liquid on top. How much of it should I use? Should I make a starter or just decant and use the cake from the quart jar?

When did you harvest?

If you believe Woodlandbrew’s research, you tossed as much yeast as you kept. And possibly kept many of the “bad bugs”.

If the yeast is ~3 weeks old, just pitch it. If older, make a starter.

harvested march 5 so will be right at 3 weeks by Monday when I plan to brew.

Made my first starter. Boiled up a 1L starter wort with 1100ml water and 110g light pils DME, cooled it and put it in a sanitized 2L growler, spooned in 4 fat rounded spoons of the harvested 1084, aerated the crap out of it and covered it with sanitized alum foil. Covered with a towel and put it in a warm dark cozy spot. I figure I’ll swirl it a few times a day til I’m ready to pitch it Monday evening. Call me the human stir plate.

@mvsawyer you need to get brewin’ man! Those primaries look sad and lonely!

Yea I know…i’ve read that and my last harvest of WL04 I just scooped into a couple mason jars and left as is. I’ll decant the liquid off and use them without rinsing. There was still a pretty even amount of yeast/trub separation in my ‘rinsed’ 1084. Live and learn or live and keep making the same mistakes with your fingers crossed.

I store my slurry in ziplock plastic bags in a small ail and use a batch either the day I harvested or within 2 weeks usually. Otherwise I make a starter, so in that event, I usually just go with new yeast in the starter. I use half of a slurry for a just harvested lager beer and about a third for ales.
