If you want a really good Red Rhone for under 25 Euro, I'd be looking for wines from Cornas.

Some of my favorite producers are Auguste Clape, Alain Voge, and Jean-Luc Columbo.

These are definitely a cut above most St. Joseph, Crozes Hermitage, and the less costly Chateauneuf du Papes.

I find them close in quality to Cote Rotie, Hermitage and the best Chateauneuf do Pape wines, for around half the price.
