Here are my findings.
It is to small to do large batches. It will hold the water, but not the grains. if i extend the grain basket walls up or maybe if I split up the grains and did one as a time?
Once it hits the temp, it stops and maintains only. You have to cool it way down or replace the water to get it to percolate again. Thinking about a byepass power switch.
The speed was very nice, it was really fast and you don't have to watch it all the time. I think I will use it for a similar use, but not exactly this.
