Why is ice wine expensive?
Preciousness of ice wine mainly lies in its lower yield, high risks,
technique requirements and contents. The following is a clutch of data: (1)
Lower yield of frozen grapes: restricted by terrestrial conditions, only
several small areas can produce ice wine in the world. (2) Low juice yield: the
juice yield of frozen grapes only lingers around 20%, while that of grapes for
common wine is 70%. (3) Smaller percentage of yield: the yield of ice wine only
accounts for 1/30000 of the global wine yield. That is to say, only one bottle
wine among 30000 bottles of wine in the world is ice wine! Moreover, production
of ice wine is a high-risk investment, since grapes used for ice wine need to
be very mature and sugar degree of grape juice after juice squeezing needs to
reach 35Brix per liter (i.e. sugar degree of grape juice is
