Knights Bridge Estate Vineyards - Knights Valley Appellation

Block 1

Block: 1

Varietal: Sauvignon Blanc Musque
Acres: 3.03
Total Vines: 1376
Average Crop: 3.5 Tons / Acre

Soils: Bidwell Creek alluvial fan composed of a relatively uniform dark grayish brown Los Robles gravelly clay loam. The Los Robles clay loam has a surface layer and subsoil of dark grayish brown well structured clay loam. These soils have 20-40% rounded river-washed pebbles, gravel, and cobbles throughout the profile which provides them with reduced water holding capacity and excellent drainage.

Clone: Sauvignon Blanc Musque- This clone from Pont-de-la-Maye, Bordeaux, France and was originally registered in California in 1974 under the name Savagnin musque, but in the 1990's Dr. Carole Meredith re-classified this selection as Sauvignon Blanc based on DNA profiling. This clone expresses citrus blossoms, melon and roasted orange flavors.

Root Stock: AXR1- A cross between Vitus vinifera and Vitus rupestris developed by Victor Ganzin, France, 1869. Widely used in California during the 60's, it adapts to environments well, has consistently high quality and modest yields, ease of propagation, and relative tolerance to most viruses.

Cover Crop: Permanent cover crop consisting of native grasses, fescues, and native clovers

Block: 2

Varietal: Chardonnay
Acres: 12.5
Total Vines: 9073
Average Crop: 2.7 Tons / Acre

Soils: Bidwell Creek alluvial fan composed of a relatively uniform dark grayish brown Los Robles gravelly clay loam. The Los Robles clay loam has a surface layer and subsoil of dark grayish brown well structured clay loam. These soils have 20-40% rounded river-washed pebbles, gravel, and cobbles throughout the profile which provides them with reduced water holding capacity and excellent drainage.

Clone: Clone 4 - Thought to be a Wente-Stanly field selection clone that was classified by Dr. Olmo of UC Davis in 1955. This clone shows great structure and displays flavors of pear, apple, tropical, and citrus.

Root Stock: 5BB- A cross between Vitus berlandieri and Vitus riparia was developed by Teleki in Hungry and then improved on by Kober in Austria during the early 1900's. It has broad nematode resistance and good phylloxera resistance. This root stock is especially suited for these volcanic soils, ensuring modest yield of high-quality fruit.

Cover Crop: "Howell Mountain Plow Down" (25% Magnus Pea, 25% Common Vetch, 25% Bell Beans, and 25% Barley)
