Unexpected LM/VM Behavior

Postby kekedog13 » Thu Jan 22, 2015 7:04 pm

I'm still learning to use this rig. Did a spirit run and once stabilized got jar after jar at a steady 82 %. The fores were 90 %. After 5 hrs the temp went up and the ABV remained the same .When the head (top of boiling vessel ) finally reached 210 F it was still putting out 80 %. I was happy about this yet puzzled how this could be.After some calculation ( and 8 hrs of running )it looked like I had gotten an adequate amount of product and shut it down. After cooling I checked abv of the back set and it read 0 ABV. Does this mean I finally learned to use it and got ALL of the alc. from it ? I've only run this rig 5 times and this time I monitored the temp of the water exiting the reflux condenser and by using a valve kept it between 115 and 120 F. I started with 40% from stripping runs.

0% abv sounds improbable though it might be possible. Did you do the temperature correction when you took your reading?
I've been running glass stills for over 20 years now and have no shame in saying so.

You may as well not bother with a slow reflux still if you are only getting 80%. That's potstill teritory.
