The old adage that you get what you pay for definitely applies to balsamic vinegar, no matter whether it’s an independent brand or a supermarket’s own-label. The best are made in Modena, Italy, and carry at least IGP (protected geographical indication) status. Though that’s not the strictest certification, it’s still a mark of quality, assuring the product has been made following certain guidelines.
None of the vinegars I tested had PDO (protected designation of origin) status, which is a more coveted certification with strict guidelines and a 12-year ageing process, and which explains why it can cost upwards of £1,200 a litre.
