It 's harvest time in Napa Valley , and it appears that the 6.0-magnitude earthquake that struck Northern California did not impact vineyards or the grapes on the vine , a local vintners ' association said . The Sunday earthquake that sent more than 100 people to the hospital also sent wine barrels tumbling and wine bottles flying in the early morning hours . Yet a majority of region 's vineyards are open for visitors . Some wineries suffered damage to their barrel storage areas , wine inventory and production equipment over the weekend , but `` there were no reports of winery employees being injured by the earthquake , '' according a statement by Napa Valley Vintners , an association of 500 area vintners . Signorello Estate , which took to social media to announce the Napa winery would be closed Sunday , reopened Monday for business , an employee told CNN . Napa 's Etude Wines stayed closed another day on Monday to clean up damage from the earthquake , but announced on its website that its tasting room would reopen on Tuesday . `` Weather throughout the growing season has been ideal and vintners are expecting yet another excellent vintage , the third year in a row in the region , '' the association reported . Vintners who have quake-damaged equipment or facilities can contact the association to find `` temporary tanks and other production equipment to help them get through the next few weeks . '' Most of the valley is operating normally , Napa City Manager Mike Parness said at a Sunday news conference . `` I 've been getting a lot of calls from people from outside the area that were planning on coming here , ( who ) are worried about it for fear this is some kind of disaster area , which means they ca n't come here and enjoy the valley , '' he said . `` Conditions will be vastly improved over the next few days as we get on top of this . '' California Lt. Gov . Gavin Newsom , who owns his own wineries , echoed that sentiment in an interview with CNN . `` I have a winemaker down the street from us -- they were devastated . Dozens and dozens of their barrels collapsed , '' he said . `` My winery , for instance , no barrels collapsed . '' Parness encouraged visitors to check with their hotels and then make a judgment call about visiting . `` Most of the places in the valley have not been impacted , '' he said . Tourists are key to Napa Valley 's economic health . The region 's nearly 3 million annual visitors generate some $ 1.4 billion yearly in direct tourism spending , according to the 2012 Napa Valley Economic Impact Study . The 13,409 travelers who visit daily together spend an average of $ 3.82 million . While the Visit Napa Valley tourism office says that most businesses are open as usual , the group noted that some historic downtown Napa businesses had been damaged . The group is keeping a growing list of open businesses on its website , but officials also suggested calling first to confirm your plans . `` It appears the majority of the damage was centered on specific areas in the city of Napa , '' the bureau said , in a press statement . `` The regions around Yountville , St. Helena and Calistoga seem to have experienced minimal damage and disruption . '' Everyone at Peju Winery , just north of Napa in Rutherford , made it through the earthquake without any injuries or damage , the company said . `` To all of our guests who are wondering , all of us at Peju Winery are fine , '' according to Peju 's Facebook page . `` Peju is open for business today ( Sunday ) and we look forward to seeing you soon ! ''
