ILLUSTRATIONS OF STAGES OF RAISINING in Muscat (and other white or green varieties) and Zinfandel (and 

other black varieties). The illustrations will also serve as a guide with other European type varieties. The berries 

in each of the four vertical rows from left to right in each illustration are designated as follows: 

Row No. 1. NORMAL 

Row No. 2. WILTED - Each berry is equivalent to 1 NORMAL berry (no appreciable loss of moisture); Muscats 

may show color change but not distinctly brownish. Bottom berries are close to the borderline of 

raisining. 

Row No. 3. RAISINING - 2 to 3 berries are equivalent to 1 NORMAL berry depending on stage of raisining. 

Row No. 4. RAISINED - 4 to 5 berries are equivalent to 1 NORMAL berry depending on moisture remaining. 

NOTE: Bottom raisining and top raisined berries illustrate the difficulty of distinguishing 

between these two stages. If a drop of juice can be squeezed out and will drop off, the 

berry is "raisining". If there is too little juice to drop, the berry is "raisined". GRAPES (European Type),
