Bag squeeze gravity test

[ArcLight]

That's the thing though, you're not letting gravity drain the bag. You're squeezing the grain with your bag, because you twist the bag, which does a really good job of squeezing (without you having to touch any hot or sticky areas on the bag).

Don't you have to twist the bag a lot?

How do you get the leverage to do so without holding it, and getting wort all over yourself?

Hard to describe without a picture. I'll try to grab one next time I brew.

Pick the thing up and give it a spin like you do a garbage bag. Then once you rest in on the paddle, a nut falls on each side. Then you can continue to twist as much as you nee.d

I usually let my bag hang for 20-30 minutes in a typical ~5kg grain bill, squeezing nets an extra litre of wort (approx 2.2lbs or so) even after the hanging. I personally don't bother anymore, I add an extra bit of grain, tweak my volumes to account for losses. Hanging still has a lower absorbtion than traditional mash tun type setups.

When I'm feeling thrifty, I throw the bag in a second pot with about 6L of water soak it for duration of boil, squeeze the crap out of it, and use the second runnings as starter wort.
