Re: Continuing the Carbon Thread
- Hello again Matt,
In my previous response, because you mentioned 90+%,
I assumed you have a fractioning column still with reflux control valve.
If this is not the case then you may need to dilute your spirit
further before redistilling because the higher the % you start with
the greater will be the vapor production rate and with some types of
still there is potential for dangerous problems if they don't have
extra latent capacity.
If you are not aware of this potential or you need some more advise
please discuss it further before redistilling at % over normal
starting wash %.
If you are an experienced hand this may seem innapropriate, just had a
flash back to my beginnings and felt it best to be sure.
