Gap’s Crown is part of the Sonoma Coast AVA and is situated at the confluence of where Sonoma Mountain and its surrounding southwest facing hills meet the Petaluma Wind Gap (Petaluma Gap). To the south, the hills of Sonoma turn southeast and channel the cool breezes of the Petaluma Gap toward the San Pablo Bay. To the north Sonoma Mountain gives way to Crane Canyon and eventually a northwest oriented set of hills. A pocket is formed by Crane Canyon and these northwest hills just to the north of Gap’s Crown, creating a natural fog pocket around the vineyard. Typically, the coastal fog gets trapped inside, taking longer to burn off during the latter days of the growing season. This lingering fog during at the end of the growing season allows Gap’s Crown fruit to ripen slowly, developing sugar and phenolic ripeness in unison.
Cool ocean breezes between the Sonoma Mountain and the Petaluma Wind Gap trap coastal fog just before harvest to ensure slow, and evenly ripened fruit.
