Which statement correctly describes enrichment and concentration in must processing?

• A. Concentration uses processes like reverse osmosis, vacuum extraction, or chilling; Enrichment involves adding sugar or grape concentrate
• B. Enrichment refers to increasing sugar content only; Concentration uses fermentation temperature changes
• C. Concentration involves adding water to must; Enrichment reduces acidity
• D. Enrichment and concentration are the same process

Answer: (A)

Concentration in must processing means increasing sugar concentration by removing water from the must. Techniques like reverse osmosis, vacuum extraction, or chilling/freezing are used to separate water and leave a more concentrated juice behind. Enrichment, on the other hand, raises the must’s sugar content by adding sugar or grape concentrate, boosting potential alcohol before fermentation. This approach is used when natural sugars are insufficient to reach the desired final alcohol level. The other ideas mix up the concepts: adding water would dilute the must rather than concentrate it, enrichment isn’t about changing acidity alone, and the two processes are not the same.
