Temp control question

[LoganO]

I just got a new refrigerator that will allow me to move up to 10 gallon batches. What is the best way to control the temp on 2 carboys? Do you put the probe from the controller on one carboy and wrap the fermwrap around both carboys? or is there a better method?

All you can do is pick one and hope for the best

Would I be better off cooling the refrigerator and then using 2 temp controls with a fermwrap on each carboy and warm up to the ferment temp?

While what you are suggesting works well (I did it for years in my chest freezer, and still do if my conical is in use), unless you are also dispensing or storing beer in the same fridge it is probably expensive overkill to use two seperate controllers and Fermwraps. I think you will get good results simply using a single temp controller with the probe in either of the carboys.

If you have the same volume in both carboys, just put your probe on one of the them... and if you have two fermwraps, get an outlet splitter, and hook that to the controller, and then the fermwraps to that. Grab a few of those stick on thermometers, slap them on both carboys (below the liquid level, and away from the fermwrap) and use those to double check that your temps are close enough.

Two controllers would definitely be excessive IMO.

Thanks I will give it a try this weekend and see how it goes!

Why not squeeze the carboys together with the temp probe between them and keep it in place with some t-shirts or bubble wrap...

Good idea, but probably more trouble than it's worth. If you have pitched the same amount, and oxygenated the same amount, and the volume is similar - then the difference between the two is negligible. That's how I roll.
