Mumford & Sons perform at BottleRock Napa Valley at the Napa Valley Expo on May 26, 2019.

BottleRock 2020 is off, officially, the event’s promoters announced Thursday. The three-day festival had originally been postponed from Memorial Day weekend to October of this year.

The new dates for BottleRock will be Memorial Day weekend 2021: May 28 to 30.

The Red Hot Chili Peppers, Dave Matthews Band and Stevie Nicks remain the headliners, though the rest of the lineup is up in the air and will be announced later. Promoters said they hope to book as many of the previously announced acts as possible.

“Although Napa County has one of the lowest COVID-19 case counts in the Bay Area, we are not ready for a large public gathering such as BottleRock Napa Valley in 2020,” Napa County Public Health Officer Dr. Karen Relucio said in a BottleRock news release. “Events like BottleRock fall under Gov. [Gavin] Newsom’s Stage 4 plan for re-opening, which we will not achieve prior to October. … Our first priority is the health of the community.”

All 2020 passes will be valid for next May’s dates. No information about refunds was initially announced.
