Introduction

Press job that contains the following procedure.

--- Filled with grapes;

--- Squeezing grapes;

--- Squeeze grape juice or wine;

--- Remove Marc.

These operations may be continuous or discontinuous, depending on the type of press.

These major operations may be accompanied by an auxiliary operations, such as. the decomposition of grapes during the machining operation.

The standard test used grape has the following characteristics at the time of filling the press.

a) Physical characteristics.

--- Is intact;

---shattered;

--- Removal of stems;

--- Removed and broken stems (stems removed before or after);

--- Whether dehydrated (dried grapes);

---other.

b) Technical characteristics.

--- Fermentation;

---heating;

--- Carbon dioxide impregnation;

--- Enzymatic treatment;

---other.
