The Agostina Pieri 2015 Brunello di Montalcino has a somewhat deconstructed or fragmented bouquet in which you can taste the warm-vintage fruit, the oak spice and the grapes' tart freshness, all in distinct and separate categories. This is true even after the wine has been open for a while. (I tasted most of these samples over a range of time.) However, these elements do come together with a smoother transition after plenty of breathing. I see this as a long-term Brunello or one that is best enjoyed after another three to five years of bottle age. It needs to evolve past the pretty youthfulness on show right now.
