Wow! That sounds like a _lot_ of evaporative loss to me. I probably lose
about the same volume over the same length of time from a barrel almost 4
times the size.

I'd guess that your losses are that high because the staves are thinner in
your barrel than they are in my 228 liter export barrels, which are an inch
thick. Either that, or you recently filled a new barrel and it's still
soaking up wine.
