I've just finished a day of work with my new SD hybrid Pot Still, above, with a Twin Coil VM type head and take off – no valve naturally – to provide enough reflux to keep the plates charged.

Absolutely gobsmacked at the result of this first test drive with the condenser fitted. The VM head provided lots of charge for the plates and once past the Heads I lifted the coil away from the take-off outlet. Take-off rate was approx 2.25LPH
Started the run with 40lt of Low Wines from Lentil Washes @ 40%ABV. Because it was all from stripped sugar head washes I decided to run it at this strength.
With 16lt of pure Ethanol in the boiler I had no real idea what output or final volume to expect from the new setup.
I discarded 500ml as Fores followed by 1.2lt of Heads at 91% (20
oC) and the following is how the rest of the run went.

Changed to Tails collection vessel after detecting Tails at 450ml in Jar 19. I turned the boiler off at 21.00 having collected 4lt of Tails and the ABV had dropped from 70% to 30% in the space of the last 10 minutes before power down.
All jars are now airing and will be assessed for cuts on Tuesday.
Very happy camper indeed. Next run out will be all grain wash from scratch – single run to see how that goes.
