Two tablespoons of powdered lye in 5 gallon bucket. Get the lye from soap making supply places. No longer available in stores for some years now due to some sort of misuse. Takes off even stubborn labels in an overnight soak.
I second jabba11 on the Colorado Brewing Nano. I have their 20 gallon unit and have found my whole process faster. Went from a 3 vessel, 5 gallon propane to 10+ gallon electric batches. It's a garage setup though for all you garagistas out there
I am going electric and a bit bigger in my setup... so I have 4 items for sale:
10 gallon Spike kettle with two horizontal ports (without thermometer and valve) $175
SOLD 10 gallon Spike kettle with two vertical ports $175 SOLD
10 gallon cooler mash tun with bazooka screen and valve $40...
