Rioja

[SAR]

O.K. I give up. When asking for advice recently on a Dry Red Wine to go into a Sassy Sangria recipe, everyone agreed that I just need a "Rioja". I don't know what "Rioja" is and can't find it in a liquor store. Is this another genric name for "Red Rose" or something else? I can't find the word Rioja on any label. What do I need to look for label or brand wise. Help and Thanks.
