You're sitting next to an aqueduct that has served this city continuously since its Roman construction, surrounded by 100+ labels of Greek wine from across the country - Xinomavro from Naoussa, Assyrtiko from Santorini and Mount Pangaio, Agiorgitiko from Nemea, Moschofilero from Mantinia. This is not a tourist wine bar. The Kamares aqueduct towering above you supplied the city that Paul landed in. This harbor - ancient Neapolis - was where the Apostle Paul first set foot in Europe in approximately AD 49, bringing Christianity to the continent. He was arrested in this city. He left anyway and kept going. The old town you're sitting in has been occupied by Byzantines, Franks, Venetians, and Ottomans. The wine bar is the most recent layer of history in this place. Oinioi wine bar is in the Panagia old town, next to the Kamares - the Byzantine/Ottoman aqueduct (navigate to the Kamares on all tourist maps and look for Oinioi immediately adjacent). Ask for the wine list ("ton katalogo krasíou, parakaló") and request something specifically from the Kavala region - Mount Pangaio Malagouzia is the local specialty. When it arrives, smell it before tasting: Malagouzia is extraordinarily aromatic (gardenia, peach blossom, citrus peel) in a way that no other Greek variety replicates.
🔄 BACKUP: If Oinioi is closed (check hours before ascending the hill), any cafe or restaurant in the Panagia quarter will serve local wine - the tavernas in the narrow streets above the aqueduct all carry regional labels.
