The 2019 Carmignano Riserva Trefiano keeps the taster at the edge of the glass, taking in its autumnal blend of clove and cinnamon-dusted black cherries, all lifted by hints of sage. This is youthfully tense with a tart core of wild berry fruits and zesty citrus. Slowly mounting tannins mingle with saline minerals toward the close, finishing staining, long and epically structured, with a crunchy sensation that lingers on. Bury the 2019 Trefiano deep in the cellar.
