Status on blackberry cognac

When I made this blackberry cognac one week ago, the cognac has it "normal" brownish colour.

However, already one day after starting this "production" the colour of the cognac had changed from brown to purple. Also the blackberries had moved from the bottom of the bottles to being free flowing in the entire bottle.

I am looking forward to tasting this blackberry cognac. It will "only" be five weeks old, when some friends are coming around for a evening of alcohol tasting one month from now, and this is according to the recipe is too young.
