VINEYARD HIGHLIGHTS

  • Perched on the western edge of Sonoma Mountain, ranging in elevation from 300' to 840' above sea level, Gap's Crown takes advantage of the steep Sonoma Mountain hillsides to promote natural airflow and soil drainage within the vineyard.
  • Developed to a high-density spacing, Gap's Crown was planted in four phases from 2002 to 2005. Blocks were laid out to best take advantage of rocky hillside terrain and promote even ripening and uniform cluster development on the vine. Hillside slope and aspect were taken into account when setting row direction in order to promote even sunlight exposure on grape clusters during the latter months of fruit ripening.

GENERAL PROPERTY INFORMATION

Address/Location

AVA
Sonoma Coast (Petaluma Gap region)

Description
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 Mountain 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, coastal fog that is trapped in this pocket takes 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.
