Default quick reuse yeast cake question

Just bottled a batch today, and am in the midst of brewing another. If I want to reuse the yeast cake in my primary fermenter, do I just leave it there, with the gunk around the top from the last batch, and pour the new wort/water on top of it?

Or do I need to move the yeast cake into a newly cleaned fermenter?

TIA

Leave it be and pour wort on top, the results will be explosive. Seriously you'll have the most vigorous fermentation you've ever had and it will start up in a hour or two. Attach a blow-off tube not an airlock unless you like cleaning up messes.

My Celebration IPA was dumped onto a 1056 cake and it turned out wonderful.

You'll also need to pitch it ideally within a few hours if you are leaving it in the primary...pitching on the cake that is.

Thanks. I'm going to give it a try. It will be less than 3 hours from the time emptied the beer from the primary til the time I'm going to pour in the new wort (less than an hour from now). I left just a small amount of beer over the yeast cake, probably like a 1/4 inch and covered the top with plastic in the meantime.

Default no activity of old yeast cake

Help!

Its been about 10 hours since I put the new wort/water over the old yeast cake, and I see no activity. No bubble from the blow-off tube, and I briefly opened the fermenter to peak in and saw no activity.

Should I wait a while longer, or pitch some new yeast?

You didn't do a secondary?

Did you pour hot wort on the cake? That would shock the yeast something fierce.

HB, I had not used a secondary, just 19 days in a primary. (Haven't yet bought a carboy for secondary, and have been doing ok with primary only so far--- I've only brewed 4 batches to date.)

Wort and water and old yeast cake were all at about 70F, probably withing a degree or two.

I did not pour in the wort to rigorously, but did pour the water on top fairly vigorously. I stirred the batch up, but didn't make any attempt to stir up the yeast from the bottom.

Pouring on top of a yeast cake doesn't mean it'll take off in quick.

I've done this many times and it still takes around 16-24 hours.

It will work though, have patience.

Thanks. Glad to hear that. Now I'll feel comfortable to wait it out for the rest of the day. 11:30pm will be the 24 hour mark.

I'll post the result either way.

OK, I was just asking those questions for clarity.

Make sure you stir the yeast up off the bottom next time. It was probably packed a little. If the yeast had been more in suspension then it may have taken off faster.
