Actually - we have been finding a few of the 30 year old ceramic bottles (and the 25's as well) in Alberta, Canada. (The place to buy whisky in Canada.)
Last few 30's purchased just a couple of months ago were a mere $220 ~ $240 Cdn. for the 30 year old. The 25 can be found for $219... Box and all...
If you can enjoy it and still e-bay off the empty shell for $75 US (>$90 Cdn.) well that should encourage some recycling, eh!!!
