You're in Greece. It's lunch. You're at a taverna by the water. You like white wine. Here's what you do.
It's always served cold, usually in a nice little jug or metal carafe with nice small cups, not a fancy wine glass. And it always hits.
Greece has been making wine for four thousand years. Every taverna pours something local, by the carafe — sometimes a glass jug, sometimes a battered metal pitcher. None of it is precious. All of it works. Trust the process.
Tip within a tip: Pantelis on Patmos. A taverna since 1950, on the harbour. Sit outside, order the Symi shrimp, ask for the house white. Life is good.
