I have read folks recommending a packet of dry or liquid yeast when adding fresh yeast to bottle condition.  What about yeast slurry though?  I imagine it would be a minute amount.

I have a Belgian tripel I am about to bottle.  To be safe I figured I would add some yeast along with priming sugar as it has been cold conditioning for many months now.  I was going to pitch a pack of dry us-05 but a) I am out and b) I happen to have some WLP530 slurry (which was the fermenting yeast) available at the moment.

So, how much?  Maybe 5 ml's of solid slurry or is even that too much?

I plan on adding the yeast and priming solution to a keg and then transferring from the keg it is in now.  Then I can purge the air, and agitate to distribute the sugar and yeast well without fear of oxidation.  Then, bottle from the keg through picnic tap/racking cane setup at low pressure.

I did it once but made a small starter first. Worked out will with much less sediment than a pack of yeast.

So did you use the wort from the starter to act as the priming sugar?

And how much yeast did you use to make the starter?  Seems like that would create more yeast than just using a packet?

Used a 1/2 tsp of slurry and woke it up with just 100ml of slurry and cut back on the priming sugar a little.

It was a Berliner Weisse and 6.8 oz of priming sugar would give me 3.5 volumes of CO2
5.5 oz calculates out to 3 volumes.
Used 100ml 1.020 wort to get the 1/4 tsp of slurry active then added priming sugar and the active wort to the bucket and bottled.

Liked the results enough to get more scientific next time.

The more I think about it the more I am thinking I should just go with some dry.  My initial choice was us-05 but again, I am out, but I do have some s-04.

Might just make life simpler.  I guess I need to check the alcohol tolerance on it though.  My tripel is in the 9% range (can't recall the exact number

S-04 makes a better bottling yeast anyway; it's more flocculent. Rehydrate about a quarter of the pack and you won't have to worry about the alcohol.

The rate that Sierra Nevada uses is 1 billion cells / L, and that's to bottle condition filtered beer.  If I rinse the yeast slurry of any trub, then I usually go with 3 billion cells/mL, which is around 6-7 mL for a 5 gal batch.  If the slurry is older you'll need more.  The tricky bit will be getting it evenly mixed in the bottling bucket.

[enso]

Whoo!  Finally got to bottling!  Man, I have not been excited to bottle something in a long time, if not EVER!

Sadly I think I may have over done the yeast dose.  I decided to go with the s-04.  From my understanding only a 1/4 packet was necessary to pitch.  Well, I did not want to have 3/4 a pack hanging around for who knows how long, so I rehydrated the whole thing.  I figured I would just pitch 1/4 of the resulting liquid.

Well, that was kind of difficult as it rehydrated REALLY well.  Thick and foamy.  So, anyway, as mentioned in my plan I then poured the priming sugar and yeast into a sanitized keg.  I then pressurized it and transferred from the keg the tripel was in.  Rocking it every now and then to mix well.

I went from pretty much crystal clear beer from being cold condtiioned for a little over 2 months to wicked cloudy.   

Ah well, live and learn.  It should flocculate pretty well but I anticipate a good layer of sediment.

...hopefully no bottle bombs as I did bottle a few regular long necks for possible competition purposes.

I wouldn't think extra yeast would account for bottle bombs unless there was enough extra sugar in the slurry being pitched.

Oh. that isn't what I meant.  The reason I fear possible explosion is because I primed for 3 volumes.  I am not sure if regular 12 oz. bottles (recycled many times) are rated for that much.  Time will tell.

I wouldn't worry about that. I use the 12 oz bottles at 3 vol all the time, and I accidentally primed a batch over 4 vol once. No grenades.

That is good to hear.  I actually may be over 3 volumes.   

I adjusted for residual co2 when calculating the amount of priming sugar.  However, I had charged the keg to 30 psi when I racked it in there and there was some carbonation from that as well...

Yeah, I've done 3.4 a few times.  No problems.
