Pietro Ratti's 2015 Barolo Rocche dell'Annunziata is the most structured and firmly textured of the Barolos presented in this tasting of new releases. This wine is tight and compact at its core, but it needs a little prodding and swirling of the glass before it hints at the grandeur and the layering of fruit nuances embedded in its very DNA. Just give it time, this wine requires a little extra patience before it fully blossoms. All those beautiful Nebbiolo complexities are hidden just below the surface and will emerge with more bottle aging. Only 5,000 bottles were made.
