When you split a larger batch into 2 carboys how do you do it?  Do you just fill one then the other or do you fill them at the same time?  if you do it at the same time please explain how you do it.

I usually start filling one, get it part way, fill the other most/all of the way, and then finish off the first one.  I don't know if it matters or not though.  I have a valve on the end of my transfer tubing so I can pretty easily stop and start the flow.

I could do that too.  I am would like to do it all in one step and tried using a "tee" last time and that did not work very well.

what was the problem?  did one tube get clogged or something?

[denny]

I fill one, then the other.

I do not think it was perfectly balanced so it favored one side.  I got a ss "U" that I will also try this weekend.

don't you do something like this when you keg or no?

I do split it with the kegs but that is also under a lot more pressure than what is coming out of the CFC and I think that helps balance it.

I fill each as I go along so both are pretty much the same.

This. Some gets more trub/hops in it but I haven't seen any difference in the two.

I guess I was trying to get equal trub in both.  I guess I could just use my hop rocket as a pre-filter and not worry about it.

[Poptop]

Just add to both simultaneously. Keep it symmetric

I'd end up with two beers when I split one after the other. My solution was to get a bigger fermenter. I never though about mixing the wort better. My buddy switches about every 1/3 of the carboy. He literally just moves the hose to the other bucket.

I have bigger fermenters but this was to do split batches with different yeast.  I guess in that regard it will not matter that much if they are slightly different seeing they will be different anyway because of the yeast.

I've done it both ways before switching to 14-15g fermenter's. I never noticed much difference either by rotating, one then the other, or a tee.

If you really want to do this what you need is something akin to a 3-way stopcock. The one below is one of the medical variety. I'm not sure if they make ones that can be connected to whatever tubing you are filling your fermentors with. With one of these in place you simply decide which output line to supply. Fill one fermentor and then just turn the valve and it switches over to the other output. You could switch back and forth indefinitely.

 

Here's one from amazon. Seems like there should be something cheaper. But this basically what you want to look for.

I set up a tee once and added some hose and looked at it and said, "what the heck, why complicate things."

I could do that with a 3-way ss ball valve I already have but ultimately I would like to fill both simultaneously.

Kinda funny.  I have never split a batch in all these years.

I've done the experiment where I split a batch with a single yeast, putting all the trub in one fermentor and none in the other. They were virtually indistinguishable after fermentation.
