I've
never done an overnight mash but having read the Posts I'm beginning to wonder why!
I like "dry" brews anyway so that aspect doesn't worry me and as I have a 32 litre insulated Mash Tun I could probably mash a 4.5kg grain bill and minimise the amount of sparge needed to top-up the Boiler to the 30 litre mark before starting the boil.
Hmmm! Got me thinking here!
At the moment, on Day One I do a standard one hour mash and then run the wort into the Boiler where it loses a lot of heat overnight.
By leaving it overnight in the Mash Tun (with extra Strike Water) it will lose a lot less heat and I could start heating the wort as soon as there is more than 1cm in the Boiler.
Yep! It looks like a Plan for the next brew; which is due in about a week.
