Patrick Comiskey’s December 2011 article in Wine and Spirits Magazine is one of the most thorough articles written about Coombsville. Capturing everything from the historical foundation of the name (Nathan Coombs’ farm, which he called “Willows”, forms the central part of what is now the town of Napa) to an exploration of the complex geologic nature of the regions soils.
A couple of favorite quotes;
“If Coombsville has an epicenter, it’s Meteor Vineyard…”
“When marine incursion layers snake in the Napa Valley from San Pablo Bay, they arrive here first and leave last, resulting in one of the valley’s longest growing seasons.”
“Almost all of the soils of the area are some combination of two components: accumulated landslide debris, something (Jonathan) Swinchatt calls colluvium: and layers of light, flaky volcanic ash, from Mt. George eruptions.”
“In addition to to the colluvium and tuff melange, Meteor’s soils have a high proportion of cobble in the mix. No one is quite sure where this cobble comes from, but the landslide activity may have pushed it there, the way glaciers push debris from one place to another. The drainage that cobble affords the soil, in addition to the air drainage down this west facing slope and the prominent exposure at the top of the knoll all combine to set this site apart. This may, in fact, be Coombsville’s cru.”
