H. William Harlan discovered an isolated territory in the early 1980s while hiking along Oakville’s southwestern ridge. The hidden expanse – ancient and untamed - moved him deeply, but remained elusive until the Harlan family finally captured it in 2008. As the second generation explored and worked with the land, they began to make discoveries of their own. At the core of this wild terrain they found a powerful geologic convergence, which had shaped its steep, rugged topography, and created the conditions for an altogether exotic winegrowing environment. Over time they found that the dramatic landscape - just beyond the edge of the known - would slowly change them, and ultimately inspire a new endeavor: Promontory.
