At Line 39, our winemakers travel across California’s vast wine regions to nurture grower relationships and secure the best available fruit sources. This unending commitment to quality provides the foundation for blending stylistic wines that are sophisticated, approachable, consistent and always enoyable. Our ultimate goal is to show wine consumers that good wine does not always come with a hefty price tag.
