BOISE -- We now have a better idea what started a fire inside a Boise brewing company Monday.
Woodland Empire Ale Craft has only been open for three weeks.
The owners tell KTVB they are going to continue to push forward despite this major setback.
They say the fire started in the boiler and smoldered inside the ceiling.
"It was a pretty tough day yesterday," said Rob Landerman.
Landerman is the sauce boss and president of Woodland Empire Ale Craft. On Tuesday, he was busy picking up the pieces from a fire that temporarily stopped production of his local beer.
"Luckily, we've got beer in all four of our tanks," said Landerman.
The fire started because the boiler, which is used to heat the water in the tanks, ran out of water. The safety valve failed to kick in, heating up the metal.
Monday morning, Landerman and a boiler repair man found the fire.
"I saw a glowing ember fall out of the corner of my eye, through this window, and so came around the corner, looked up and there was a hole in roof about the size of a basketball," said Landerman.
Firefighters were on scene a short time later to keep the fire from spreading even more in a building that was built in 1905.
While there is never a good time for a business fire, three weeks into opening has to be one of the worst times.
"I kind of felt like I was at the end of my rope, you know," said Landerman. "It's been an up hill battle, it's a labor of love, you know. There's been a lot that we've had to overcome to get here and we kind of felt like we were just coming over that cusp and then something like this happens, it's just a big slap in the face."
The fire and boiler not working has prevented them from making any new beer, but luckily there is still beer on tap and they can move forward. Their tasting room will be open tonight.
