We Are JaM

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.

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.

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.

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.

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!

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.

Say hello to bold, smooth Butter Cab and crisp, effervescent Butter Bubbles! These delicious additions shine alongside the creamy OG Butter Chardonnay and on-the-go ButterCans. Whether you're craving a refreshing white, bold red, or a bubbly, there's now officially a Butter for every occasion.

After the success of Butter Cab and Butter Bubbles, Butter Wines introduces another delicious red, NEW Butter Pinot Noir! Juicy, lush, and incredibly smooth, Butter Pinot Noir is the go-to for girls' nights in, cozy dinner parties, and fireside sips with friends.
