Hello,
While I've no direct experience, you're talking about getting imto a very specialist type of asset, so unless you've a large diversified spread of investments, I'd recommend against investing in whiskey.
I've heard a lot of experienced investors talk about whiskey, and some even say it's great, just increases in value as it agrees, but in reality - few really know anything about it, and it's exposed to specific legislative / regulatory controls, that could have a massive impact on value etc.
