If you're driving from Diakofto to Kalavrita, make a stop at Tetramythos. The winery attributes the high quality and refined flavor of its reds and whites to the location of its vineyards on the northern slopes of Mt. Helmos, which protects the grapes from hot winds. Tours and tastings are available year-round, weekdays 9–4 and weekends 9–7.
