The same is true for Italian wines: Vino da Tavola is not a protected name. You can make anything that qualifies as vino (that's to say, fermented Vitis Vinicola without sugar added), and call it Vino da Tavola.
This is contrasted with DOC, which is almost usually higher quality, with the possible exception of the case of a truly wonderful very small producer that is doing experiments and has not bothered to register his stuff as DOC.
