Wildfires in California are threatening vineyards in the Napa and Sonoma wine-growing regions. We'll keep you up to date with the latest news as firefighters tackle blazes fuelled by high winds.

Tuesday 1200 BST: Media has reported ten fatalities so far and 1,500 homes and building destroyed in the fires, that started early on Monday morning. Nine of the deaths have been in Napa and Sonoma, where much of California's wine industry is based. About 20,000 people have been evacuated.

Tuesday 1220 BST: Australia-headquartered wine group Treasury Wine Estates has released a statement saying that all of its employees in the region are safe but that there has been some damage to its infrastructure. The company, which has extensive operations in Napa and Sonoma, including its Napa-based Americas headquarters, said that the majority of its vineyards and wineries are not presently in the direct fire zones, while most of its current vintage has been picked. Only 10% of grapes are still on the vine.

It added: "Based on what we currently know, there is limited damage to TWE's infrastructures and sites, however the fires are ongoing and TWE still has limited access to all of its assets in the region."

Tuesday 1240 BST: Trade group Napa Valley Vinters has confirmed that some winery employees in Napa have lost their homes to the fires and that some of its members' wineries have been destroyed or damaged. The group's offices are currently without power, but staff have issued emergency information for anyone caught up in the fires, including a live incident report from Californian authorities.

Tuesday 1243 BST: The Californian fire service is sharing some dramatic pictures on its Twitter account showing just how near the fire is to vineyards.

Tuesday 1451 BST: The Wine Institute, the trade body for Californian wine has issued an update on the fires.

In a statement, the group said: "Multiple wildfires spread across large portions of Napa and Sonoma counties Sunday night and early Monday morning, forcing thousands from their homes, burning hundreds of structures and scorching over 30,000 hectares. Several wineries were destroyed including Signorelli and there was significant damage to both Darioush and Stag's Leap, who lost some buildings.

"The two largest blazes are in Napa Valley's eastern hills, near Atlas Peak, and in the northern part of Sonoma's city of Santa Rosa where the damage looks urban rather than rural but far more destructive. Smoke taint issues will be discussed in the aftermath of this but hopefully this should be minimal as luckily harvest was nearly complete. Long term damage to vineyards might take longer to ascertain."

Wednesday 0946 BST: The fires are now heading into their fourth day, and media report that the death toll is now at 17. US President Donald Trump has declared the area a major disaster and greenlit government assistance grants.

Wednesday 0954 BST: The Wine Institute has issued an update.

It said: "We have been in touch with the winery organisations in regions impacted by the fires to offer assistance. Right now, they are focused on ensuring the safety of their communities, offering assistance and gathering information. Assessments of vineyards and wineries cannot be made until the fires are contained.

"It is too early to know what impact the fires may have on the 2017 harvest or wines from the vintage. The majority of grapes in these areas, and statewide, were harvested earlier in the season."

Thursday 0900 BST: The death toll now stands at 23, according to media, with firefighters saying the situation is still "very serious". The expected return of high winds is also predicted to make matters worse.

Thursday 0910 BST: There is good news from Treasury Wine Estates, which announced that there has been limited damage to its Stag's Leap and Chateau St. Jean wineries.

It said: "At this stage, the great news is we can confirm that the Stags' Leap Winery and cellar door, including the Manor House, were not damaged by the fire and the infrastructure remains intact. Additionally we are able to share that Chateau St. Jean sustained only minor damage to an out-building, with cosmetic and landscaping damage."

Thursday 0920 BST: A local newspaper, The Mercury News, has a list of wineries damaged or destroyed in the fire. Click here to read. Meanwhile, a Forbes article predicts that the fires will affect California's wine output for years to come.
