Which of the following represents a disadvantage of organic viticulture?

• A. Lower yield in difficult years, greater reliance on copper sprays, cost and time of certification
• B. Higher yield in all years
• C. No copper sprays needed
• D. Lower soil health

Answer: (A)

Organic viticulture emphasizes reducing synthetic inputs and relying on ecological soil and plant health practices. This approach often means vines are more vulnerable to stress in difficult years, and without the ability to use certain conventional fungicides and growth aids, yields can be lower when conditions are challenging. To manage disease and vigor within organic rules, copper-based sprays are commonly used, so there is a greater reliance on copper compared with conventional systems. The certification process to label wine as organic also adds ongoing costs, audits, and time for compliance, which can be a notable disadvantage for producers. The other statements don’t fit: higher yields in all years aren’t typical, copper sprays are indeed used in organics, and organic practices don’t inherently mean lower soil health and can actually improve soil quality through organic matter, cover crops, and compost.
