WINE QUALIFICATIONS

• Wines from a SPECIFIC VINEYARD must be 95% from that vineyard.

HOW IT ALL COMES TOGETHER

Rain, fog, sun, and daytime vs. nighttime temperatures are climatic factors that impact the grapes. And ultimately the wine. For example, morning sun on one slope produces wine with different characteristics than wine from the same varietal and vineyard receiving afternoon sun on another slope. The terroir can be cooler or hotter depending on nearby vegetation, such as a forest, which cools, or a lake that warms. Rain or irrigation promotes natural sugar content of the grapes. A river or ocean can moderate temperatures so that flavor-boosting acidity is not lost. more...
