I'm pleased to report that after talking with Rick Wasmund,
I went ahead and ordered three of his charred 2 litre barrels
(they also offer 5, 10, 18.5, and 194 litre sizes.) Shipping
for the 3 empty 2 litre barrels was less than $9. US. I'm not
sure about International sales but if you're interested, I'd
suggest mailing Rick to inquire.
I was able to order the Wasmunds 124 proof spirits from
another source and am looking forward to starting a barrel
project of my own.
