There are more than 400 examples of typical Tuscan produce, but only 31 have the EU quality certificates that attest to their authenticity. The DOP and IGP certifications (PDO and PGI in English) guarantee that the customer is buying a food product made in accordance with strict quality controls. On the consortia websites you will find all the information you need about production methods, about how the businesses produce and distribute their wares.
Fresh, seasoned Pecorino Toscano DOP, for example, is a cheese made exclusively with whole milk from sheep in Tuscany and on the fringes of neighbouring regions, as is traditional. These sheep graze mainly on natural meadows, and the unique, delicate flavour of their cheese tells a story that starts with the Etruscans and continues to the present day. If you want to have it delivered to your home, here are the companies that sell it through their online shops.
The production line of Olio Toscano IGP is rigorously controlled in Tuscany, from the olive grove to the packaging. This oil, moreover, undergoes scientific and tasting tests, the latter conducted by recognised commissions from the Ministry of Agricultural Policy, in order to confirm that it completely adheres to quality controls. The Consorzio dell'Olio Toscano IGP has put together a list here of companies that offer home delivery (and without shipping costs).
