I have never tried this but have read old posts from those who did. This is how they make Valpolicella Ripasso. Maybe you can buy an inexpensive kit (i.e RJS Grand Cru Intl Primitivo) and try it. Just taking a stab on what to do, but add the pomace to the kit when you start fermenting. Someone please jump in, as I would like to try this myself.
I like a good Valpolicella Ripasso
From a Google search:
Ripasso is an ancient wine making technique used for centuries in Valpolicella wineries and now become very popular among wine enthusiasts. Ripasso, sometimes also called double fermentation, is a method used to give more structure, body and flavours to the basic Valpolicella wine.
In Autumn, after harvest, selected grapes for the
Amarone and
Recioto remain in
lofts above wineries to dry for four months.
On the other hand, all other grapes are squeezed and fermented to make the
basic Valpolicella Classico wine.
At the end of January, beginning of February, the semi-dried grapes for Amarone and Recioto are squeezed and fermented together with grape skins. After a long skin contact fermentation grape skins are removed and wine is then stored for the ageing.
The basic Valpolicella wine that has been fermented in Autumn is then put over these Recioto and Amarone
skins that, being still full of un-fermented sugars, start a
second fermentation. These skins still contain
aromatic compounds,
tannins, etc. that thanks to this second, short fermentation are transferred to the simple Valpolicella wine. Ripasso is an Italian word meaning “
review“, “
go over again“.
Valpolicella Superiore Ripassois often referred to as “
the poor man Amarone” or “
baby Amarone“. Producers are not happy of these definitions but it is true that Valpolicella Ripasso is a wine that is in between the basic Valpolicella wine and the Amarone, sharing the freshness, the lightness and the value for money of basic Valpolicella wines, and some of the structures and flavours of the Amarone.
