I do BIAB with double milled grains and get ~80% efficiency. I am comfortable with 80%, but I wanted to make the post to double check to see if I was missing out on any big positive aspects on a higher %.
Thanks for all of the answers. I use a BIAB and have an efficiency ~80% with double milled grains. I'm still a beginner and won't be at the point of needing to get a very consistent batch any time soon, so it's good to know I don't need to stress about it too much or rush to buy a recirculating...
Besides having to spend a little more money on grains to make up for a low mash efficiency, are there any other downsides to having a low efficiency?
EDIT: I use BIAB with double milled grains and get ~80% which is typical. I just wanted to see what the reasons are for trying to bump the % up...
