• Age of Block is very important
• Crop load and or fruit size
• Storage index of fruit at harvest (mineral analysis)
• Block History – has it gone long term before?
• Fruit pressure
• Malic acid content
• Fruit starch content
• Willingness of grower to take a chance
– Growers tag bins Green(good), yellow(bad) and Red(Ugly)
