We Are JaM

Rich, Bold, Californian Wines to Love Every Day

Our wines live up to their names: rich & bold Butter (Chardonnay, ButterLight, ButterCans, Sauv Blanc, Pinot Noir, Cab, and Bubbles), and berry-licious JaM Cabernet. We make easy-to-love wines that celebrate every day!

John and Michele

Meet the “J” and “M” in JaM Cellars — second-generation Napa Valley vintners, wine & music lovers and fans of fun, John and Michele! They are the “J” and “M” in JaM.

“After almost a decade crafting ultra-premium wines in the Napa Valley, we decided to make some super-approachable wines that could be enjoyed anytime — whether that’s a special occasion, an everyday celebration, or any day of the week that ends in Y!”

— John and Michele

JaM Cellars History

1995
Where it all Began

From humble beginnings in vineyard management, John Truchard, second-generation Napa Valley vintner and founder of the Butter brand, used the skills passed down from his father to launch his own vineyard management business—perfecting his craft and saving to one day plant his own vineyards and create his own wines.

2008
Introducing JaM Cabernet

Second-generation Napa Valley vintners, music lovers, and fans of fun, John & Michele (the "J" and "M" in JaM) turned a challenging economy into an opportunity. The husband-and-wife duo launched JaM Cabernet, a high-quality Napa Valley wine for under $20—making great wine accessible to all.

2010
Everything’s Better with Butter

The success of JaM Cabernet sparked the creation of Butter Chardonnay—rich, creamy, and melts-in-your-mouth. What began with just 1,000 cases is now a nationwide favorite and the #1-selling Chardonnay in the U.S. ($13+ category). Today, Butter Wines stands as a beacon of approachability, quality, and downright deliciousness.

Butter Gets a Home in Napa

John and Michele Truchard open the JaM Cellars Wine & Music Studio in downtown Napa, completely reimagining the traditional tasting room. With live music JaMSessions, late-night pours, and an atmosphere straight out of a recording studio lounge, it quickly became a must-visit destination for wine and music lovers.

2016
BottleRock’s Better with Butter

JaM Cellars becomes a presenting sponsor of BottleRock® Napa Valley, making Butter Chardonnay the ultimate headliner. The first-ever JaM Cellars Stage features music icons like Stevie Wonder, Lenny Kravitz, and Red Hot Chili Peppers—and the tradition continues today, nine years and counting!

CAN You Believe It?!

Butter Chardonnay became the #1 best-selling single SKU of premium Chardonnay in the U.S. ($13+ category), so naturally, it was time to celebrate with NEW ButterCans! The first-ever Butter line extension was a game-changer, bringing the same creamy, melt-in-your-mouth Chardonnay in a convenient, grab-and-go format, quickly becoming the #1-selling Chardonnay in a can.
