Concur with the WS review below, although I dropped my score one point and would add that the wine presently requires hours of natural aeration—no less than four in the bottle! We tested the use of a Vinturi, which produced unsatisfactory results. Perhaps decanting would take less time. Paired with pistachio crusted rack of lamb. 
WS: 92. A fragrant and elegant red, delivering tuberose, strawberry, cherry and grassy aromas and flavors. Taut and balanced, with bright floral and red fruit notes gracing the lingering finish. Best from 2024 through 2038. 375 cases made, 150 cases imported. — 3 months ago

Good but surprisingly not great. — a month ago
A mid cherry red in colour. Aromatics of red fruits, menthol and touches of tar and roses. Light to medium bodied on the palate - surprising for a Barolo with medium plus intensity. Different and interesting in a good vintage from an excellent producer. Next in a year. — 7 months ago

A continuation of sharing my early impressions of the 2021 vintage in Barolo; Cavallotto is one of those benchmark producers for me, inextricably connected to Bricco Boschis, which they have farmed for nearly 100 years. Popped and poured; enjoyed over the course of a few hours. The 2021 Bricco Boschis pours a brilliant garnet color with a transparent core; medium+ viscosity with no staining of the tears. On the nose, the wine is developing with powerful notes of Morello cherry, dehydrated orange, cumin, tar, roses, talcum powder, fresh sage and fresh mint, and dried gravelly earth. On the palate, the wine is bone dry with structure like that of Helm’s Deep; the tannins are absolutely rippin’ and acid at medium+. Confirming the notes from the nose. The finish is extremely long, savory and drying, to the point that you feel it in your gums several minutes. A brilliant Barolo that has a very long life ahead. Drink now with plenty of air and patience through 2071. Pairs well with hearty lasagna and baseball. — 8 hours ago
