Good natural wine doesn't need to cost a fortune. Under €20 gets you organic Gamay from Auvergne, biodynamic Grüner Veltliner from Austria, crisp Alsatian Pinot Gris, structured Aglianico from Campania. 

These aren't entry-level wines. They're everyday bottles from producers who farm responsibly and price honestly. Some are light and crushable. Others have serious depth. All of them prove you don't need to spend big to drink well.
