Making up a mash tun using a 160 liter ice box and for the bottom drain stainless steel woven mesh from a 2 meter washing machine water inlet hose. Seem to be a very fine filter, maybe too fine.
If I use finely ground corn, almost like flour, what are the chances of the drain blocking?
The mash will have barley and wheat added as the mash temperature drops. I have used cracked corn before but not in a true mash tun.
