How It Started

We start with the best quality grapes possible. Our first grapes came from Northern California’s winemaking sweet spot, the 39th parallel. Today, we grow grapes in the very best regions across California. Our talented winemaker and his team ensure every varietal tastes true to its nature—so our Chardonnay will always taste just like a Chardonnay should. And we put our very best into even the smallest details, so all you have to do is sit back, relax, and enjoy a glass of simply good wine.

Sustainability is a Key Ingredient

To us, great fla­vor comes with account­abil­i­ty — that’s why we’re ful­ly trans­par­ent about the way we make our wine. We’re com­mit­ted to sus­tain­able prac­tices that are good for every­one — our team, our land, our part­ners, and our fans.

From work­ing with cer­ti­fied sus­tain­able grow­ers to respon­si­bly recy­cling our waste­water, we’re inte­grat­ing sus­tain­able, envi­ron­men­tal­ly friend­ly prac­tices into every part of our wine­mak­ing process, with a goal of becom­ing a ful­ly sus­tain­able oper­a­tion. We’re hon­ored to have received offi­cial Cer­ti­fied Cal­i­for­nia Sus­tain­able Vine­yard Win­ery cer­ti­fi­ca­tion from the Cal­i­for­nia Sus­tain­able Wine­grow­ing Alliance for our efforts, and we’re con­tin­u­ing our con­ser­va­tion work to pro­tect the fields, vine­yards, and com­mu­ni­ties we call home.

Meet Steven Decosta

  • Line 39's Natural Born Winemaker

    Steven DeCos­ta knew what he want­ed to do long before most of us had a clue. At the ten­der age of 12, asso­ci­at­ing the pres­ence of wine with good food and hap­py fam­i­ly gath­er­ings, he set out on a path that would solid­i­fy his place in California’s pres­ti­gious wine­mak­ing world. He stud­ied chem­istry and micro­bi­ol­o­gy, earn­ing a degree in Enol­o­gy from Cal­i­for­nia State Fres­no in 2010, and has been using a bal­ance of sci­ence and phys­i­cal craft to make ele­gant, approach­able wines ever since.

  • Today's Steven DeCosta

    Today, Steven DeCos­ta leads a team of tal­ent­ed young wine­mak­ers who work with grapes from pre­mier appel­la­tions across Cal­i­for­nia. Their vari­etal focus is on aro­mat­ics and hon­est fla­vors every­one can enjoy — from tra­di­tion­al reds to vibrant whites. DeCos­ta also over­sees research and devel­op­ment and intro­duces new tech­nol­o­gy that can deliv­er on Line 39’s promise of scal­ing the bou­tique wine expe­ri­ence, so that good wine can exist in everyone’s glass.

Good Grapes. Good Relationships

Craft­ing high qual­i­ty, true-to-nature wines starts with good grapes. And good grapes come from our last­ing rela­tion­ships with California’s pre­mier grow­ers, many of whom come from the region our wine is named after. The 39th par­al­lel runs through the heart of North­ern California’s wine coun­try just North of Napa Val­ley and has always pro­vid­ed rich tra­di­tion, inspi­ra­tion, and yes – grapes!, for our blends. Today our rela­tion­ship with grow­ers extends beyond this wine­grow­ing epi­cen­ter to include the equal­ly superb cool-cli­mate areas along the Cen­tral Coast, the sun-drenched vine­yards around Lodi, and the rich vari­ety of ter­roirs in Sono­ma Coun­ty. All our vine­yards fos­ter slow, even ripen­ing of the grapes, enabling us to pro­duce wines with a per­fect bal­ance of rich, ripe fruit fla­vors and crisp acidity.

In oth­er words, to us, Line 39 is more than a place – it’s a state of mind. One that can only come to life through the rela­tion­ships we build with California’s most tal­ent­ed growers.
