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.
