No problem! For what it’s worth, that’s actually the volume we use the CF15 to ferment (11-12g batches). Nice amount of headroom for vigorous fermentations and with 11-11.5g wort going in it fills 2 cornies almost perfectly down to the trub line.
I have a CF15 I’m looking to sell - live few hours south of you in central PA. Planning to list it in the For Sale forum, but if you’re interested please feel free to send me a PM.
