Extract brewer considering BIAB

[hotbeer]

Appreciate this info. One of my hesitations with BIAB has been the idea of material escaping through the mesh and causing bitterness or off-flavors during the boil.

When you go finer on the bags you increase the time it takes to drain. You also chance it plugging up with all the really fine stuff.

An issue I had with one bag I made was the material was so tight a mesh that it didn't let water into the bag.

As has been mentioned by others, it'll just become trub on the bottom of the FV. So the only downside might be the volume it takes up in the FV leaving you little head space.

I've not seen any association with whether I put clean wort or everything in the FV as having any affect on taste or clarity of the final product. If I had to lean one way or the other, the ones that had a lot of trub and took longer to clean up were more enjoyable beers.
