In Korinthia, you must buy the small, sweet and dark Corinth Raisin. You can learn more about how it is processed and produced in Pyrgos. The town is also where lotuses are cultivated, offering you a new sensation in tastes. Buy lotuses directly from the source for the best variety.
If you're in Korinthia in early September, pass by Zemenos for the annual grape festival. In late September there is an apple festival in Manna.
Good seafood is common is Western Korinthia, particularly in the picturesque villages between Corinth and Patras (Perigiali, Assos, Vrahati, Kokoni and Velo). Try char-grilled fish, olives, fried cheese and local wine, as well as the octopus which you might see hung out and drying under the sunshine.
Many wineries are available that offer you sampling and have workshops that are open to the public, such as the Pirgakis Winery. See more in the Wine section.
