Which factor is not listed as affecting temperature and sunshine levels for vineyards?

• A. Latitude
• B. Soil pH
• C. Altitude
• D. Wind

Answer: (B)

Temperature and sunshine a vineyard receives are shaped by climate factors that influence the amount of solar radiation and the air temperature reaching the vines. Latitude sets how high the sun sits in the sky and how long days are, which drives overall warmth and growing-season light. Altitude tends to cool the air and can increase diurnal temperature variation, altering daily warmth and how much sun effectively reaches the canopy. Wind modifies the vineyard’s microclimate by moving air, which can cool surfaces or, in different conditions, reduce cloud cover and boost sunshine exposure.

Soil pH mainly affects vine nutrition and microbial activity in the root zone, not the amount of sunlight or ambient temperature the site experiences. That’s why it’s not listed as a factor influencing temperature and sunshine levels.
