Yes, it will be a 23 litre batch.
However, the reference to 70 little 'uns is for the load about to exit the fermenter. Am just waiting for a callback from the missus to see if the right sized giant plastic storage box is at her shop so she can bring some home before I start bottling. I'm still ever so edgy about doing all glass bottling for now, especially after seeing some of the pics in the current bottle bomb thread. I figure the thicker LDPE walls of a storage box will be more likely to contain shrapnel than my usual cardboard crates.
The IPA will most likely be in PET.
Thanks for the hint to increase the first hopping to 30 minutes. I shall give it a shot. If it all works out well, then it's on to the espresso hop extraction experiment.
Cheers - Fermented.
