OK,
I see what you are getting at...
They ferment on the skins, which will boost up the tannins, then age in a barrel to obtain some micro oxidation, flavor, and also color.
In years past, I have made batches of white that were macerated for about a week and never had a white wine turn orange. I am thinking that the barrel aging is most likely what gives the wine its color.
I have also found that skin maceration of white wines made the wine very tannic and bitter, qualities that most do not like in white wines. As a result, my white wines were not very popular with the family and I ended up doing less and less each year. Even without maceration, my whites continued to be overly tannic and bitter.
I then had a conversation with the lead winemaker at the Unionville winery (a great guy) and he advised that I should go with a "whole press" method. His thinking was that even the act of crushing/desteming white grapes can make a wine overly tannic. He said to try just simply tossing the whole clusters into the press and go "low and slow" with it. I took his advice and MAN was he right! The result was crisp, clean, and soft.
So, in short, the direction I am taking my whites is directly opposite of what you want to do..
I would say that I make white wines to suit MY tastes and not yours. I admit that the process you propose looks very interesting and I am curious. If you do try this, please let us know how you make out (pictures would be great).
Let me ask, have you ever tasted an orange wine? Did you like it?
