I tried to find the original post about the new mash tuns with no avail.
Just wanted to say thanks for the new mash tuns! These things are legit.... As someone who checks the mash temperature several times during the mash, these new tuns hold temps SUBSTANTIALLY better than the old ones. Plus they're incredibly lighter due to not being water-logged.
For those that check efficientcy, I wouldn't doubt you'd see an uptick in yours using these new tuns.
Cheers!
