Firefighters continue to battle a fire at Ramsbury Brewery, near Marlborough.
Damien Bence, group manager for the fire service, has confirmed that the fire broke out in the building's grain silo building.
No people were injured in the fire.
Speaking from the scene, he said: "The incident involved the Ramsbury Distilling Company, we've had a fire in one of their grain silo and general storage areas.
"Luckily on-one was involved, which is the main thing.
"We've had ten pumping appliances from around the area and multiple support appliances that have also assisted them, including an area ladder platform and a water visor.
"We've been here since 5.30am this morning. The fire has mainly been extinguished, what we are doing now is extinguishing the hot spots that still sit in the warehouse."
Fire investigators are continuing to work out the cause of the fire. Owners of the distillery are also on the scene.
Damian added: "We have difficulties because the building is metal clad and the structure has started to cool due to the heat.
"Firefighters can't go into the risk area so are fighting it from outside."
The majority of firefighters that dealt with the incident are on-call.
