Chalone. Volcanism and tectonic activity define Chalone and the Pinnacles National Park, immediately below which lies the exceptionally situated Boer Vineyard. First planted by Dick Woodward to Cabernet in 1969 and celebrated as the ‘A-Frame’ vineyard, the vines on these steep slopes were grafted several decades ago to several selections of Pinot Noir. It is now owned and farmed by Richard Boer. Chalk from an ancient, uplifted seabed and decomposing granite comprise this highly unusual and prized terroir. There is sufficient maritime influence to moderate daytime temperatures and ensure fruit ripens evenly.
