I have observed basically two types of labels on this forum. One is the type that likes to get artistic and change the label for every batch, type of wine, they make. As a result the labels look nothing alike. The other type is to use the same basic label and just change the narrative to descibe the wine in the bottle. I guess if you are not trying to establish some sort of brand recognition then changing the labels is not a problem. I prefer to leave the labels basically the same between the wines except for describing what is in the bottle.
But to answer your question, I read an article a few days ago that told what was "supposed" to be on the label. If I can fine the article I will send it to you.
