The EU protects True Neapolitan Pizza: new regulation and certifications

Authentic Neapolitan pizza is now protected in the EU by the geographical certification "STG" (or "TSG", traditional specialty guaranteed). The European Union, with Regulation 2022/2313 accepted the request sent by Italy to protect the name and methods of preparation of one of the main symbols of Made in Italy in the world.

With this decision, therefore, no one will be able to use the name "Pizza Napoletana" (or "Neapolitan Pizza") unless accompanied by the wording STG.

New rules for the protection of the authentic Neapolitan pizza

To avoid imitations or improvised interpretations of Neapolitan Pizza, the EU has expressed its willingness to protect this typical specialty of the Italian culinary tradition, rewarding the certification only those who follow the original recipe. Among the characteristics of STG certification:

• cooked in a wood oven [emphasis mine]

I think that it may be legal, since it sounds like Italy got the "Neapolitan Pizza" protected post-Brexit.
