Discovery of Mini Casks

Today I discovered mini casks and I can't wait to get one.  I'm going to get some single malt Scotch Whisky and age it to see if it makes a difference over the course of six months or so.  At least that's what my plan is now.  This place has them all the way down to 1 liter...that sounds perfect for a first time experiment. They say the smaller the cask the quicker it matures.  I figure if I start with maybe some cask strength stuff I can't really go wrong.

I think I'm going to go with the 1 liter cask from this place (shown above):
