Natural wine in Greece is not a marketing category — it's a return. Ancient Greek winemakers used clay amphorae, wild yeast, and minimal intervention. At Heteroclito (St 2 Fokionos & Petraki, near the Diocese of Athens), the 20 by-the-glass selections change every month. Whatever you taste today will not be available next month. Ask the staff: 'What is your most unusual wine right now?' This is not a trick question — they stock things nobody else in Athens carries. Expect €8-15 per glass. Then ask what grape it is and whether you can buy a bottle to take with you. Open Mon-Thu 12:30 PM-midnight, Fri-Sat 12:30 PM-1:30 AM, Sun 6 PM-midnight.
🔄 BACKUP: Ask specifically for an Agiorgitiko (the Saint George grape, from Nemea in the Peloponnese) or a Malagousia white (rediscovered in the 1970s by Carras Estate from near-extinction). Both are available at Heteroclito in natural-wine interpretations you will not find at any other wine bar in Athens.
