Fogged bottom plate

Postby r1zzla » Wed Nov 15, 2017 1:15 pm

This morning I did a run - 60L MacRum on 4 plates.
All went OK got the expected yield (around 6L @ 100% from 6L @ 10.5%).

Usually all the SGs clear whilst the foreshots are being taken off, then all stay clear until the onset of tails. I usually use the first bit of fogging on SG one as the first indication of tails.

This time the bottom SG had water droplets / fogging from beginning to end.

The only difference between this run and previous runs is a complete strip down and clean up of copper etc. But did a steam run prior to the rum and all clamps were checked for leaks.

An ideas as to what causes this ?

I've had this happen a couple of times as well. Not sure what causes it. Funnily enough they have been rum as well. I put it down to poor quality alc in the wash or running too hard. There seemed to be alot of tails in those runs. Whether the ferment wasn't any good or maybe smearing.

I didn't go much further into it than that so I'm not much help and I could be way off on the reasoning. It will be interesting to see what your spirit turns out like, fingers crossed it will be fine :handgestures-thumbupleft:

I get the same from time to time too with rum. Never really thought why that might be, but Woody's thoughts are worth considering and further exploring next time it happens for me. Taste doesn't appear to differ for me... :think:

I was running it a the same pace as all the other gens (.3L/hr FS, then 1.5l/hr for next 1000ml then 1.9l/hr until tails).
I tried an early cuts test this morning .. not good seems to go straight from heads into tails, so into the rum feints jar with the whole run :crying-blue:

I'll try stripping the Neutraliser down and rebuilding it before the next run.

Yep that seems the same as mine, straight from heads to tails. Not sure what causes it, not speed by the sounds of it so wash might be the culprit. I doubt its the still if you got the right amount of alc from it but could be :think:
