Even though I am generally partial to reds, these hot summer days convinced me to take a look at the white side of wine. Last week-end, I purchased 2 of them, the first one is ‘Cote Est’ by Domaine Lafage (Cotes Catalanes). 
Made in Canet en Rousillon (France, near the Mediterranean) not far from the Spanish (Catalan) border of 45% Grenache Blanc, 48% Grenache Gris, 7% Macabeo, it displays summer fruit flavors without being sweet. Consider it as a good substitute for a chenin blanc or a sauvignon blanc. It should be found for around $9.00/ $10.00.
The second one was recommended to me. 
From Galicia (Spain) Burgans ‘Albarino’ (Rias Baixas) is drier, has more acidity, and green apple flavors and worked well with some sea scallops. Made with 100% albarino grapes, its name come from the Burgans hills in the Salnes Valley. The area happens to be rich in both wines and ancient Celtic ties. The logo on the bottle actually reminds me of what we in Brittany call a Triskell. Expect to pay about $13.00.
Enjoy one or both, I hope you can find them easily.
