Juice concentrates for brandy making

[MooseMan]

So I'm finally getting around to looking at Brandy making.

Reason being, I'm now able to get my hands on several different fruit juice concentrates in pretty big volumes.
These are mostly 6x concentrated juices at 65brix so I won't need to add any sugar, I'll be quite heavily diluting!

I'm ok with wine making as I've been making all types of wine for many years.

But are there any pointers that the brandy guys could offer, on the best process for creating a wine deliberately intended to be distilled to brandy?

Then further to that, when it comes to distilling the wine, are there any nice tricks I should be aware of?
Likewise aging, I'm intending to age in glass with fruit wood turned to charcoal, but if this is not a great idea please tell me I'm being dumb.

I'm excited to get started and I've already got a few batches of wine going.
