The equivalent process to FWH would be to add them to the kettle once your mash is done. If you transfer your BIAB mash to a different kettle to boil you can add them to that kettle, and transfer the warm mash on top of the hops. If you don't transfer, you can throw them in the mash once the grains are pulled out, and let them sit while you rinse (sparge) the grains. Just let them heat up with the wort.Is there any way, or has anyone ever used the first wort hopping technique with this method? I have been interested to use it, but unsure how to do it.
You can always add them to the mash too!
