I've said previously that I'm sure the 200 litre bourbon barrels will be excellent .. the new-make was excellent and the barrels freshly emptied bourbon.
With regard to the wine casks which I think were, 697 French oak, 699 American oak, 701 French oak, and 704 American oak, they contained 225 litres. They should taste quite different from the bourbon and from each other, spicy, peppery perhaps?
When I offered the option of a tenth share in the wine casks I don't think all buyers took up the opportunity to go for a twentieth shares in two casks. The new-make was the same so it should be interesting to taste the difference the wood makes. Some of these casks were Seguin Moreau, which I think is highly regarded by some other whisky distilleries.
For some info on different cask types, see http://www.barrel-shop.com/oakbarrels/se...uin-moreau.html
I think only four casks that are now 8yo were sold in shares but there were others which are currently younger than 8yo.
It might be a good idea for the owners of the above four casks to agree to bottle the best two casks and (subject to agreement of everyone)divide the bottles equally among all shareholders.
If you wish you could then re-cask the other two into something different maybe fresh bourbon or sherry and leave it for a couple of years. This should give you enough bottles to be going on with and lower bottling and duty costs. In any case it appears that Martin is reasonably flexible, so the choices are yours to make.
I've never considered it a good idea to bottle half a cask and leave the remaining whisky to mature in a half empty barrel.
