FIELD NOTE 01

Regions Influenced by the Sea's Cooling Effect

In Russian River Valley, the fog coming in from the Pacific is important, and you can learn with a focus on Pinot Noir and Chardonnay. Cool conditions near the ocean are also essential in Sonoma Coast. Study not just distance from the coastline, but the routes through which the fog moves inland.

FIELD NOTE 02

To the region of Zinfandel

In Dry Creek Valley, Zinfandel is the representative variety. Each area of Sonoma has a different varietal mix and landscape, so you cannot assume wines are the same based solely on the county name. Ridge's Lytton Springs is a study case for the region's blend and barrel aging.

FIELD NOTE 03

Organize inclusion relationships

The Sonoma County administrative area, the Sonoma Coast AVA, and the individual smaller AVAs each cover different geographical ranges. When comparing them, align the scale of regional names and consult the official map to confirm which vineyard is included in which designation.
