Hi guys I am new to biab ie. never done it before, I am wondering would there be an effect on efficiency using a bag that is a lot smaller that the kettle. I have a bag designed for a 50l keggle and I want to use it in a 300l kettle as kind of a partial mash. The bag its self can hold about 20kg or ...

Hi all, I am from Ireland, brewing for a couple of years all grain and extract, on a 33l plastic bucket kettle system. I have a keggle being made and just ordered my BIAB bag.
Time to fill up the brain a little before the bag!
