Tap water on Kefalonia is quite safe to drink but it may have a different taste to what you are familiar and you may prefer to buy water that’s been bottled at one of Greece’s many natural springs. This is widely available in the grocery shops at little expense. In April, 2019, Greece won three 'gold' awards for its still bottled water at the prestigious Gourmet Waters International Contest in Paris.
On the islands it’s not uncommon to see locals filling water containers at springs, e.g. at Vrisi (literally, ‘spring’) in the village square at Tzanata, near Poros. In the village of Hionata the old wash house, on the road to Katelios, has been preserved for prosperity. Although Kefalonia is well blessed with water the supplies can run low in summer so please don’t waste water.
|I remember one elderly lady visitor who refused to buy bottled water because it was a ‘funny colour'. I explained that many grocery shops sell wine ‘from the barrel’ in plastic water bottles. After this we noticed she consumed quite a lot of bottled ‘water’. Yiamas!|
