Passerillage, where cut bunches of grapes are sun dried in order to increase the concentration of sugar; I I 1 80 2. Noble rot, where a fungus perforates the grapes' skin, allowing water in the grape to evaporate during dry conditions, and thereby raising the sugar concentration in the remaining juice; 3. The ice wine technique, where grapes are harvested and pressed after being frozen on the vine (similar to cryoextraction, where the harvested grapes are artificially frozen to -6C before pressing). Explain why this last technique results in a sweet wine. d) In Canada, maple syrup must have a sugar content of at least 66 brix (66 wt% sugar) in order to meet the legal definition. A producer notices that their syrup boils at 103C. Can they sell it?
