Racking a wine means

  • A.Adding sugar to raise the final alcohol content
  • B.Warming the wine to encourage a second fermentation
  • C.Filtering the wine through a sterile membrane
  • D.Drawing the clear wine off its sediment

Answer: D

Correct answer: Drawing the clear wine off its sediment

Racking transfers the clear wine from above the lees into a fresh vessel, leaving the dead yeast and precipitated matter behind. It is done several times during maturation, and it also allows a controlled small exposure to air, which helps the wine develop - though too much invites the acetic acid bacteria.
