Can I put Double batch one fermentor

[thinus]

Hi if I make two separate batches of all grain beer in 2x 12,5 l can I put both in same fermenter and then pitch my yeast ( 2x 11g yeast ) ??

I’m not sure I understand you volumes so I won’t address how much yeast to pitch, but yes. You can put two batches of wort in one large fermenter.

A solera is a style that adds and takes away from one batch as it works. You might want to look on this site for posts about that if you are blending different recipes for the wort.
