I dont believe that redistilling an already aged product will retain many of the nice flavours and have never heard any of the big guys doing it. But love to be proven wrong.
Charcoal clearing is the way to go imho and I will do some experimenting in the next months.
I think this is the charcoal Doc recommended:

Does anyone know what the advantages of a dedicated charcoal filter unit are ? I was thinking of just doing a batch activated charcoal treatment (without SS column). Add powdered charcoal to spirit and give it a good stir, then filter. Would think that this approach will give me more fine control over amount of charcoal per liter of product and can be more easily tuned to remove colour but retain more of the flavours ?
