Rich, Bold, Californian Wines to Love Every Day
Our wines live up to their names: rich & bold Butter (Chardonnay, ButterCans, Cab, and Bubbles), berry-licious JaM Cabernet, juicy Toast Sparking, and Sugar Sweet White. 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
John Gets Dirty
Employing the skills his father taught him, John (the “J” in JaM) starts a vineyard management business, growing grapes for others, getting his boots on the ground, flexing his vintner skills, and saving funds to one day plant his own vineyards and make his own wines.
JaM's Debut Performance
Husband & wife team John and Michele respond to the economic downturn by launching their namesake wine label, JaM Cellars, with the bold and berry-licious JaM Cabernet at under $20.
A Star is Born: Butter Chardonnay
A byproduct of a simple conversation at the Pebble Beach Food & Wine festival, the success of JaM Cabernet prompted us to create the rich, creami-licious Butter Chardonnay starting with just 1000 cases. It's now sold in all 50 states!
The Lineup Expands
Toast Sparkling joins the JaM lineup — Butter, JaM and Toast are not just for breakfast anymore!
JaM Gets a Home in Napa
The JaM Wine & Music Studio in downtown Napa opens its doors and turns the concept of a tasting room on its head. Open late with daily happy hour toasts and live music JaMSessions – imagine a recording studio’s eclectic lounge (except you don’t have to be a groupie to hang here).
BottleRock & JaM Cellars Team Up
Our inaugural year as a presenting sponsor at BottleRock made for a festival of epic proportions. Stevie Wonder, Lenny Kravitz, and Red Hot Chili Peppers are just a few of the artists who graced the very first JaM Cellars stage.
Turn It Up to Eleven
Butter Chardonnay becomes the #2 selling chardonnay in the US’s $12+ category! To celebrate, we release ButterCans, your favorite creami-licious chardonnay in a convenient, on-the-go 4-pack that quickly became the #1-selling chardonnay in a can.
Wine and Music — What a Sweet Relief
JaM Cellars begins our partnership with Sweet Relief — livestreamed JaMHappyHours featuring Lisa Loeb, G.Love, and more — to raise money to help musicians in need. Read more here.
