Big batch in two separate brews the same day

[dude1]

As my burner will not be powerful enough to boil a ~26Gal (100L) batch and my kettle won't be large enough either, I'm considering brewing a first half, transfer it to the fermenter, pitch half of the yeast and then brew the second half and add it to the fermenter along with the remaining yeast.

I'm just wondering if there is anything to worry about, such as shocking the first yeast that will already have started its process when I'll transfer the 2nd half of the wort some 4-5h later.

Thanks

I'd wait and pitch once you add the second batch to the fermenter. Man 26 gallons that's a lot of beer lol. I'm sure it doesnt matter too much though .

"Welcome to the party, pal!"

Are you using your regular fermenter to ferment all 26 gallons? I agree with Jags--there's no real problem waiting to pitch your yeast. I do it all the time with lagers when I want to cool them in the fermentation freezer to lower than my immersion chiller can get them before pitching.

Another option, referred to as a Texas two step is to brew the large batch over two days.

Brew half day 1 and pitch yeast. Brew half day 2 and add to fermenting first half.

I’ve done it...it works well.

Just dont pitch any yeast until adding them together. 4 or 5 hours isnt going to make a difference.

Your kinda doing a no chill at that point....brew and pitch yeast the next day is the standard no chill. Your pitching 4 hours later and ahead of the no chill method that many do....I wouldnt worry

Cool.
You mean the yeast that will have had time to multiply in the first 24h will be enough to add the second half of the wort without having to add the 2nd half of the yeast.
Or maybe it means adding all the yeast to the first half of the wort on the first day.
Thanks

Put ALL the yeast into the 1rst batch.
That will give it a little time to mutiply so that when you combine it with the 2nd batch, you will have more yeast over all. wilserbrewer has the right idea.

OK perfect

Just add all the yeast at once. Another method is to brew a high gravity wort and then dilute it when you get transfer to the fermenter.

As long as you're adding the second batch at the same temp as the first, the yeast isn't going to care at all. Pitch the yeast in the first batch, get them going, then add the second batch when it's ready

I was talking to a local commercial brewer who has the same issue, i.e., their BK isn't large enough to fill a fermenter, so they need to do two batches. They pitch the yeast after the first batch. Think of the first batch into which you've pitched the yeast as a large starter.

Just make sure the temperatures of the two batches are as close as you can get so you don't shock the yeast; that shouldn't be too much difficulty.

Ahhh the first batch as a large starter . Ok I can see that . I guess pouring the second batch in will help with aeration as well. The Texas two step lol.

I had read about the Texas two step, then one weekend I brewed Saturday and pitched yeast.

I brewed a similar batch Sunday, and once the wort was chilled, I looked at batch 1 starting to kick off, and a lightbulb lit lol.

I married the batches, and the yeast had quite the party tearing thru both batches!

It works! I posted here about it and a couple pundits didn’t think it was a good idea, then a couple more knowledgeable pundits imo, posted and discredited the naysayers lol.

How was this marriage consummated?
