Without skin contact 13:38 Jul 13, 2011
"Fermentation without skin contact" is another way of saying that the juice is separated from the skins as soon as possible, before it ferments, in order to avoid the transfer of harsh, bitter polyphenols to the wine. But since the cells under the grapeskin also contain aroma compounds, skin contact for white wines tends to be a matter of how much time the winemaker reckons is necessary to achieve the desired result.
Skins contain colour compounds so skin contact is necessary if you want to make a red or pink (blush, rosé) wine. However, you can make a white wine from red-skinned grapes if you remove the skins before fermentation, as in the case of sparkling wines obtained from pinot noir/nero.
As Deborah says, it would be nice to know what kind of wine your customer is making. |
