Step 1 : Introduction to the question "Which country is granted the right to be Europe's sole producer of feta cheese?"
...Only Greek feta can be labelled feta under EU law, which defines it as a brined cheese made in Greece from sheep milk, sometime mixed with up to 30 percent of goat’s milk. Feta cheese is considered the “white gold” of Greece’s economy. The country produces about 120,000 tons of feta every year, while the total domestic production of sheep and goat milk is about 1.1 million tons annually. In 2013, the EU struck a deal with Canada in which feta made in Canada would be called "feta-style" cheese, and would not depict on the label anything evoking Greece.
