This week’s word is Must...

According to Karen MacNeil‘s The Wine Bible:

The juice and liquidy pulp produced by crushing or pressing grapes before fermentation. 

The solid portion of the must, composed of skins, seeds, and sometimes stems, is called pomace.  Making must is the first step in the winemaking process.

After the must is created, it is transferred to tanks or fermenting bins to cold soak for a period of time.  The length of time that the pomace stays in the juice is a crucial determinant in the final character of the wine.  It’s a key factor in determining a wine’s color, flavors and aromas. Once the winemaker determines the time is right, the juice is drained off the pomace and fermentation is started. It’s fermentation that turns the juice into wine!

The leftover pomace is typically returned to the vineyard for fertilizer.
