Sauvignon Blanc
Technical Specifications
Aroma Profile
Citrus blossom, white peach, Meyer lemon, fresh-cut grass, subtle flint
Flavor Profile & Terroir Character
Bright grapefruit and lime zest on entry, transitioning to stone fruit mid-palate with a crisp, mineral-driven finish. The volcanic soils of Big Valley impart a distinctive saline, almost flinty quality that elevates complexity far beyond typical California Sauvignon Blanc.
Winemaking Applications
Exceptional for single-varietal bottlings, barrel-fermented programs, and high-acid blending components. The natural acidity and mineral backbone make this fruit highly sought after by both commercial and artisan producers.
Petite Verdot
Technical Specifications
Aroma Profile
Violets, dark plum, blackberry, graphite, dried herbs, leather
Flavor Profile & Terroir Character
Deep, inky concentration with powerful tannins and a long, spice-driven finish. The elevated UV intensity at Big Valley's 1,329-foot elevation produces exceptionally thick skins and phenolic depth. Dark fruit core of cassis and black cherry, framed by earthy volcanic mineral notes.
Winemaking Applications
A premier blending grape for Bordeaux-style programs — adds deep color, structural tannin, and aromatic complexity. Also exceptional as a single-varietal expression for producers seeking bold, age-worthy wines.
Sauvignon Verdot Musqué
Technical Specifications
Aroma Profile
Intense rose water, lychee, white jasmine, ripe peach, honeysuckle, orange blossom
Flavor Profile & Terroir Character
Exceptionally aromatic and floral on the nose, with a lush, textured palate of tropical fruit and stone fruit. The Musqué clone delivers heightened aromatic intensity compared to standard Sauvignon Blanc, with the volcanic mineral terroir adding a grounding savory complexity to the opulent fruit profile.
Winemaking Applications
Highly prized for aromatic white wine programs, blending with Sauvignon Blanc to add floral lift and aromatic complexity, and for late-harvest or dessert-style wines. A rare and distinctive offering from the Big Valley.
Cabernet Franc
Technical Specifications
Aroma Profile
Fresh red cherry, raspberry, violet, cedar, green bell pepper, dried herbs, tobacco
Flavor Profile & Terroir Character
Elegant and aromatic with a silky mid-palate and refined tannin structure. The coastal breezes that funnel through the Mayacamas passes slow ripening and preserve the varietal's signature herbaceous lift and bright red fruit character. A beautiful balance of fruit, earth, and structure.
Winemaking Applications
Versatile and highly sought after — exceptional as a single-varietal bottling, a Bordeaux-blend backbone, or a blending component to add aromatic complexity and mid-palate elegance. Pairs beautifully with Petite Verdot from the same terroir.
White Riesling
Technical Specifications
Aroma Profile
Apricot, white peach, petrol (with age), lime zest, slate, honeysuckle, green apple
Flavor Profile & Terroir Character
Bright, racy acidity with a crystalline purity of fruit. The volcanic mineral soils of Big Valley impart a distinctive slate and wet stone character that is the hallmark of great Riesling terroir worldwide. Natural high acidity ensures exceptional aging potential and versatility across styles from bone-dry to late-harvest.
Winemaking Applications
Exceptional for dry, off-dry, and late-harvest styles. The natural acidity and mineral complexity make this fruit ideal for producers seeking food-friendly, age-worthy white wines. Rare in California — a distinctive offering that commands premium positioning.
Lake County's Legacy Fruit
Bartlett Pears
Aroma & Flavor Profile
Classic Bartlett fragrance — ripe banana, honey, fresh pear blossom, vanilla. Buttery, juicy texture with exceptional sweetness balanced by bright natural acidity. The volcanic mineral content of Big Valley soils builds a depth of flavor and aromatic complexity that distinguishes Lake County Bartlett pears from those grown in other California regions. Exceptional sugar development from the lake-moderated growing season.
Market Applications
Fresh market, processing, canning, juice, and specialty food programs. Lake County Bartlett pears have a century-long reputation for premium quality recognized nationally since the 1889 New Orleans World's Fair.
The Terroir Behind
the Fruit
Volcanic Soils
Rich in obsidian, pumice, and volcanic ash — imparting complex mineral character found nowhere else in California.
Coastal Breezes
Afternoon winds from the Pacific funnel through the Mayacamas passes, preserving natural acidity and extending hang time.
1,329' Elevation
Up to 10% more UV radiation than sea-level valleys — producing thicker skins, deeper color, and concentrated phenolics.
Clearlake Influence
California's oldest natural lake moderates temperatures year-round, extending the growing season and buffering extreme heat.
