Hi I have 15 liters of BWKO that has been sitting for 15 months now at 65% on various degrees of char that I obviously didn't monitor closely enough and is now has far too much oak flavor.
What do I do with it is there a good way that will save the time already spent aging or am I back to the beginning.
The way I see it is my options are.

Add some nuteral spirit to dilute the oak.

Rerun it through the bubbler and age again.

Add some unaged BWKO and age.

Add to a BWKO wash boiler charge rerun and age.

Any suggestions or input would be greatly appreciated.

I've usually blended it with other aging stock.

If you have any white dog un-oaked stuff i would slowly add this so it has same whiskey flavor but slowly dilutes the oak down, i wouldnt use neutral

it might be over oaked at 65% but pretty tasty watered down to 40%. Try that first and see what it is like!!
