I think this is pretty much ready. Three months or so does sound far too quick, but given the small 3 liter barrel and large surface area contact, I think this might be enough. I also think it strikes a nice balance between fruit, which is still discernible (it was a zin) and alcohol (which has tamed down a bit, though I'm not sure why) and an intense butterscotch and caramel nose from the oak. I think any longer and the latter would completely overpower everything else and become cloying. Also a touch of vanillin sweetness. Very nice.
So let's say here she is. Brandy. Made entirely by hand in the 6 foot radius of my kitchen. Grapes courtesy of Elke and Kieran since mine were all eaten by a big fat rat this season. Really.
