My apologies if you already saw this at homebrewtalk… but I did build it for sake after all, I hope you don’t mind me posting it here too!
I’m scaling up my sake batches. I don’t have the luxury of a nice cold winter to keep the moromi chilled, so I built this:
I have a short writeup of the build here:
The box took an empty drum from ambient (about 80 degrees) down to 36 degrees fahrenheit in a day. I then filled the drum half-full with 78 degree water and it took about 5 days to cool that down to 48 degrees.
Up next: building a rice steamer that can handle 50-lbs of rice.
