Description

JaM Cellars Wine and Music Studio is known as a lively venue with cool girl vibes in the West End area of downtown Napa. You may have had their very popular Butter Chardonnay which was launched in 2010 by second-generation vintners John and Michele Truchard (JaM) and has grown to be the #1 selling Chardonnay in the U.S. ($13+ category). They have since added Butter Cab, Butter Bubbles, Butter Pinot Noir and, for those looking for less or no alcohol, ButterLight and Butter Zero. In other words, a Butter for everyone!

There's always something happening at JaM Cellars. They are well-known as presenting sponsors of BottleRock since 2016 and often host BottleRock after parties. Their Happy Hours are Mon. - Thurs. from 2-5pm and the menu offerings are at a very reasonable price point of $5-10 each. In addition to Happy Hours, they have bottomless Mimosas on Sat. and Sun. (10am-12pm), Sunday Singo-Bingo (2-4pm) and live music Fri. & Sat. (8-10pm). Check their website for all the latest events!
