You are asking the question. I used to be a translator for Spanish wine merchants. La Rioja is a very famous wine region in Spain, producing very good dry red wine, as well as sherry, which is Jerez in Spanish. Glorioso should be the trademark of this bottle of wine, which means "glory, glory, glory". DOC should be an abbreviation, but I really can’t figure out what it is. Is it the abbreviation of "Docena"? That means it should be twelve years of wine. Or is it "docilidad"? It means "docile", referring to the taste? You'd better write it in Spanish so I can understand it all.

Additional answer: That’s easy to say. GLORIOSO should indeed be a name, just like "Great Wall" and "Changyu". La Rioja Alta is the Rioja Alta region.

Denominación de Origen Calificada is indeed a level. I have seen it, but I forgot the exact Chinese translation. Literally translated, it means "with the assessment title of origin", which means the origin wine you are talking about. Nowadays, many foreign wines in China are imported into bulk wine and bottled domestically. If they have this mark, they should be bottled directly in Spain and originate from the Rioja region.
