I'm wanting to distill a very weak beer 2-3% in a 12" 16 Plate column still with a 1000L bain-marie boiler but could do with some help on still temperatures.
I would love to heat my still with our wood chip boiler which can only get up to 90°C and from what I've been reading to get ethanol out of a 2-3% wash I would need to be up at 98°C or so to be able to get it all out?
If I do need the extra few degrees I was hoping I could fit electric elements either inside the still itself or in the bain-marie sump and close my boiler off and allow the elements to heat it the rest of the way.
I am looking into ways of increasing my wash % but I don't want to add anymore sugars as this will take away from what I'm aiming to do.
Any advice would be greatly appreciated.
