Which item is NOT listed as a winery material used during winemaking?

• A. Sugar for enrichment
• B. De-acidification agents
• C. Carbon dioxide
• D. Bottling line

Answer: (D)

During winemaking, the focus is on inputs and tools that act on the juice or wine as it ferments and ages. Sugar added for enrichment is used to adjust the must’s sugar content, influencing potential alcohol and body. De-acidification agents are applied to balance acidity and improve flavor stability. Carbon dioxide is employed to create inert atmospheres in tanks or for purposes like sparging and pressure control, especially in sparkling wine production. A bottling line, however, is packaging equipment used after fermentation to fill and seal bottles. It isn’t part of the winemaking process itself, which is why it isn’t listed as a winery material used during winemaking.
