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.


Steven Decosta leads a team of talented young winemakers who focus on creating wines with character that come from premier appellations and fruit. Working to ensure the highest level of winemaking standards are met, he also oversees research and development and introduces new technology that’s implemented across the winery. Steven uses his foundation of chemistry and microbiology to create wines with a varietal focus of aromatics and flavors that consumers will enjoy. He earned his Bachelor of Science degree in Enology from California State Fresno. When Steven is not in the vineyard or production facility, you can find him traveling, cooking or reading philosophy.
