From my research we have such an advantage over the 'big boys', oaking in small containers is efficient, oaking in large containers takes years to complete the task, I guess they need repeatability with volume where as we are entirely focused on a few bottles of Gucci booze.
My beer brewing mate made a batch of unhopped malted grain beer for me to still, we shared the booze, here it is before stilling.

The not so scotch single malt is now sitting on these,

These pieces are made from a year seasoned British oak, baked at 180 degrees for 2 hours and then charred with a gas torch, some more than others.
They have had 2 cycles of neuking and are now sitting under vacuum on my window cil enjoying the sunshine, I hope they taste as good as they look!
