I know Scotch must stay in cask for a least 3 years. I know also that casks can be reused and sometimes are being charred to "open" the surface for better maturation.
Now my burning question...
What if you shred old casks into grainsize peaces and toast it. Then you let the new spirit drain through this granulate, before it is collected in the spirit reciever.
Ofcourse then you will have to mature this spirit into whisky in at least three years.
What will the result be? A very well matured young whisky? or perhaps a illegal made whisky? or a whisky with pre-maturation in stead of finishing? Or an incredible wrong whisky perhaps?
This question is not to offend people and their opinion, but only to look in a different way to whisky and satisfy my endless curiosity.
