I have a few general distilling/bourbon questions for those with the knowledge.

1. What is alcohol concentration of a fermented mash / how much mash equals how much distilled alcohol?

2. Where do the big distillers get their barrels from? Are they made in-house, or outsourced? Perhaps BettyJo can help me out here.

3. If they are outsourced, how much do the distilleries buy them for? The price that I am coming up with is $250, just seems expensive to me.

I know I am going to come up with a few more questions, so plan on seeing this thread referenced in the future again. Thanks a lot guys and gals.
