If you want to enjoy palomino white wines I have two top tips: first give them time in the bottle and then give the bottle time once open. In particular I have found that these wines by Mario Rovira have improved in the bottle – those lucky enough to still have the 2014s really sing their praises.
This one, the 2016, is probably a little unready: aromatic with an apple and sweet herb nose but slightly murky in appearance and just the slightest touch heavy on the palate. Fresh start then that apple and a touch of bitterness, then a touch of fennel leaf or anis coming out in a persistent finish.
Very enjoyable but I reckon you might want to keep this a year or so.
