Piero Busso is a family-run winery in Barbaresco known for a clean, transparent style. Their Piero Busso Barbaresco San Stunet comes from a high Treiso vineyard that gives red fruit, lift and a clear mineral edge. It’s a focused, quietly powerful expression of the site. Best enjoyed between 2026 and 2036.
Piero Busso Barbaresco San Stunet 2021 comes from a 1.5-hectare plot in Treiso, sitting at around 400 meters — the highest vineyard of the estate and part of the San Stunet MGA. The vines were planted about 35 years ago on calcareous-sandy soils, facing south-east, which gives Nebbiolo steady light and slightly cooler temperatures. Fermentation happens with natural yeast in steel tanks, followed by ageing in large barrels and a quiet stretch in bottle to settle everything in. The 2021 vintage shows a lot of bright, pretty fruit — ripe cherry, redcurrant — with a touch of warmth from the year. That red-fruit profile quickly leans into earthier tones, crushed stone and slate. It’s a clean, expressive take on Treiso Nebbiolo, and a good example of how focused this vineyard can be.
Piero Busso Barbaresco San Stunet 2021 comes from the San Stunet vineyard in Treiso, one of the estate’s highest sites at around 400 meters and holding its own MGA status. The soils here break away from the blue marls of Albesani and Gallina — San Stunet is all about yellow marl with a strong limestone presence, which gives the fruit a different kind of lift and precision. The south-eastern exposure brings steady sunlight but slightly cooler average temperatures, so the grapes ripen a bit slower and keep their clarity. This vineyard naturally produces Nebbiolo with a higher concentration of aromas, and the 2021 shows that clearly: focused, bright, expressive.
