This wine is corked.
Sa di tappo: sah dee TAP-po. Sa di = 'smells/tastes of'. Tappo = cork.
Use when a wine has the musty, wet cardboard smell of cork taint (TCA contamination). Any sommelier will replace a corked bottle immediately — don't hesitate to say this.
Sa di means 'it smells/tastes of'. Tappo is the cork. Wine that 'sa di tappo' has been contaminated by TCA (trichloroanisole), a compound that gives a musty, wet cardboard aroma. This affects 2-5% of cork-sealed wines.

Broader question — covers corked, oxidised, or other faults.
Sa di aceto — è ossidato?
It tastes of vinegar — is it oxidised?
Ossidato — oxidised. Different fault from corked.
Può cambiare la bottiglia, per favore?
Could you change the bottle, please?
Perfectly acceptable request at any restaurant or winery.
Italy's cork comes mainly from Sardinia and Calabria, where Quercus suber (cork oak) forests are extensive. The cork industry employs thousands, but TCA contamination has led many Italian producers to switch to screwcaps (tappo a vite) or glass stoppers — a still-controversial choice in traditional regions.
