Definizione

A piece of wine making equipment used to remove the stems from the grape bunches before the grapes are pressed and fermented. […] Stemmer machines are often combined with a crusher and are known as "Stemmer Crushers." 1

Nota

The stems can leave a bitter flavor, and are rarely used in white wine. Some red wines benefit from the tannins that the stems impart, and so are added back in. 2
In modern mechanized wine production, the grapes are normally crushed and stemmed at the same time by a crusher-stemmer, usually consisting of a perforated cylinder containing paddles revolving at 600 to 1,200 revolutions per minute. The grape berries are crushed and fall through the cylinder perforations; most of the stems pass out of the end of the cylinder. A roller-crusher may also be used. Ancient methods of crushing with the feet or treading with shoes are rare. 3

Contesto

The new EuroSelect destemmer made by Scharfenberger Company has no rotating basket. Instead, it relies on a continuous feed and mechanical "fingers" to remove stems. 7
