What determines the number of rackings needed during sedimentation?

• A. Size of storage vessel
• B. Temperature
• C. Type of wine
• D. Duration of fermentation

Answer: (A)

When wine settles, you’re separating the clear liquid from the solid lees by moving it to a new vessel. How many times you need to rack depends on how much sediment there is to remove and how thoroughly you want the wine clarified. The size of the storage vessel matters because it sets the total amount of wine (and thus the total lees) you’re dealing with. A larger vessel generally means more lees to separate, which often requires more rackings to achieve the same level of clarity. Temperature and the wine’s type can influence how quickly sediment settles, but they don’t determine the total number of rackings as directly as the volume being settled.
