Piney River Brewing in the early days (before expansion)
As I wrote Thursday, the recipes I’ve posted while thinking about Learn to Homebrew Day might look a little scary to a beginner. I would not call the recipe for Sweet Potato Ale that Piney River Brewing in Missouri contributed to “Brewing Local” easy, but it is so inviting it seduces you into think it might be.
Piney River Brewing first brewed Sweet Potato Ale in 2012. “We were looking for a fall seasonal beer to brew that was not another pumpkin beer. “People in the Ozarks are well known for taking something from the field or forest and transforming it into something more,” co-founder Brian Devine said. Garden plots are common in the Ozarks, and sweet potatoes often end up at the Thanksgiving table in the form of a casserole or a pie. “We used sweet potato pie as our inspiration for this beer because it is our preferred field pie in the fall,” he said.
The sweet potatoes are roasted with skin on, then peeled and mashed before they are added to the mash. Devine does not expect them to increase the gravity of the wort. “After the roasting process, we normally cool the potatoes overnight and allow the sugars and the juices to continue running out of the potatoes,” he said. “The sugars in the potatoes vary drastically every year, so I try to leave the juices out as much as possible to maintain consistency. This process leaves me with roasted sweet potato flavor and color the sweet potatoes add to the beer.”
