Grilled Sardines is typical Spanish. The dish deserves a Spanish white wine with fresh acidity. Albariño is a perfect match. Also note that Alvarinho is the Portuguese name for the same grape.
A French Sauvignon Blanc, like Pouilly Fumé from Loire, will also work very well.
The Greeks would drink Assyrtico.
Italians would drink Vermentino.
Everyone would like a sparkling Rosé.
Make it a habit to eat and drink local. Expand your skills to understand the passion that wine communicates. Explore the range of possibilities a grape can express through culture, terroir, and climate.
