About Newton Vineyard:
Peter and Su Hua Newton purchased one square mile of tumbling slopes high up on Spring Mountain overlooking St. Helena in 1977. The Estate was planted to Merlot, Cabernet Franc, Cabernet Sauvignon and Petit Verdot. Merlot thrives in a land which is rocky mixed with clay beneath the surface, while Cabernet Franc and Petit Verdot like an impoverished soil, and Cabernet Sauvignon is happy in stony loam. The mountainous slopes of the vineyards not only have these soils, but also a full range of exposures. Spring Mountain provides the vines get all the sunlight they need without any baking heat stress.
Chardonnay needs chalky or loamy soil in a cooler region. Newton owns an old vineyard in Carneros and also has long-term grape contracts for several hillside vineyards verging on that region. Newton Unfiltered Chardonnay, introduced in 1990, is said to be the first unfiltered wine produced and sold in California, and is now regarded as an industry benchmark.
Su Hua insists on picking only ripe grapes from the vine. Her method of quality control is to be involved in every aspect of the harvest, during which time she can be found every day among the pickers. To ensure that only ripe grapes are harvested, there can be up to four separate pickings in a single vineyard - very difficult to do but, she believes, there is no other way to produce a great wine.
