Here’s a great DIY on how to distill that rice wine using a rice cooker.
A still has two parts, a boiler and a condenser.
A rice cooker/warmer makes a great boiler.
It’s got a rubber gasket so all the steam goes out the vent. It’s insulated so all the heat goes into the mash.
A plastic garbage bag makes a great condenser.
It’s got lots of surface area, cooling and condensing the vapor very quickly.
In my experiments it didn’t need to be vented and hardly puffed up at all.
I tested my still by distilling a gallon of “rice wine for cooking” which has salt added to it to keep people from using it as a beverage. I put the bag in a tub to keep it from rolling off the table when it got heavy, and in case the bag leaked.
