I normally make 5 gallon batches. Thinking about splitting the wort before boil to use half for a NEIPA with some hops at flame out, then hopstand at 180 then add hops 3 days into fermentation then dry hop. It came out magical last time as a full batch. Then the other half in another pot use bittering hops at 60 then the same types of hops on my "normal" IPA schedule, hops at 10 minutes and after 14 days in the fermenter dry hop for a week.
My main concern is will i boil off too much when boiling smaller batches? Have never tried small batch before. Am i wrong to assume the 60 minute boil i am used to using stays the same with 2.5 gallons in the pots? Maybe keep them covered so it can't boil it all away? Or add more water planning on it boiling down? Of course it is entirely possible i am just paranoid (but that doesn't mean no one is following me).
Any input appreciated. Thanks in advance.
