A Spanish Mystery

Look closely at the label...not a lot there..don't bother turning it around...nothing out the back door.
OK..so we Googlers check the net..Nada!
As it was a gift over the festive season..no information there either.

First impression..raw, slightly burnt smell...then spices developed....then a more intense blackcurrant. An earthy style...dry tannins...and a swig of acidity. My guess is there is some Cabernet Sauvignon in there.
Left half the bottle to try next day.....and it showed much softer..rounded flavour...no edges...and again..some CS in there....not bad. Will I ever know more...?
