I had an inexpensive XO handy so I used that instead. I can get a nice one for 16usd at my local liquor store and think it's more rich than vsop. I did not try blending with vsop, but it would probably work as well.
I just racked and think I took a bit of the sediment....grrrr
Based on the head space seems like it will take a minimum of a .375ml bottle, easy. I think it may be close to .500ml
I'm heading to the store and will buy the VSOP 40% E&J Brandy and will also put an oak spiral and probably some other dessert wine to top it off, probably the Vanilla Fig.
