I am in the process of getting my new 2L American Oak barrel(I retail them) curred and ready to take a filling of Bourbon.
I would like to hear peoples thoughts on what bourbon I should use first. I am hoping that on each fill the barrel will not only transfer the characteristics from the wood but the previous bourbon used, so I would like to use a fairly 'strong' product first.

I have just emptied a bottle a Scotch into another barrel for the same purpose, I used a bottle of Glenfiddich 21yr old Gran Reserva
