I'll definitely do some aging on chips and/or staves but I'd like to get a barrel going that would be nicely aged in a little less than 2 years for a special occasion. I know that a barrel that's too small will over-oak in that amount of time. One that's too large wouldn't have time to really impart flavors and, though I have a pretty good capacity in terms of equipment, I couldn't realistically fill up a barrel that's very big.
I've seen a couple of barrel size comparison charts that indicate that whiskey in a 10 liter barrel for around 4 1/2 months will be equivalent to a full-size barrel for a year. If that's at all accurate, then 2 years would give me a equivalent of a 5-year aging. Does this sound about right? I know that a lot will depend on the barrel, whether it's first-use or used before, the quality of the toast and char, etc. Might that time be a little too long and risk over-oaking?
I wouldn't have any trouble filling a 10-liter and that's an amount that seems like a reasonable maximum amount to work with and have on hand. If it made more sense, though, in terms of time and volume, I could manage to fill a 20 liter.
I'd like to hear about any specific experiences and any other advice and insights will be greatly appreciated!
