I’m not generally a GF brewer, but I thought it would be interesting to try an all sweet potato mash. I diced six lbs of potatoes and boiled with a gallon of water for half an hour, then roughly mashed them into a soup with a potato masher. I let it cool to 152, then added amylase and kept it between 148 and 152 for 90 minutes. After that I poured everything through a mesh bag, squeezed to get most of the wort out, and dunk-sparged the bag in another half gallon of water.
I ended up with around 1.25 gallons of lowish gravity wort. I brought it to the boil, added a small dose of Mosaic hops, and boiled for half an hour until I was at 1.042 and around .75 gallons. Added more Mosaic for a 5 minute hop steep at 180, then cooled and pitched yeast.
No idea what this will taste like, although the sweet wort was pleasant (tasted *much* sweeter than the gravity would indicate). I’ll post some notes after I carbonate the finished beer!
