Last Wednesday I brewed an imperial stout partial mash recipe. My OG was 1.090 which is right about where I wanted it. I pitched 2 packets of Irish Ale Wyeast 1728. Fermentation took off like crazy but only a couple millimeters of krausen formed after a couple days. After 4 days there are no visible signs of fermentation so I took a gravity reading 1.050 nowhere near my target. One of the smack packs never swole and was dated Jan 12 2012, it's been between 65 and 68 degrees, and during the mash I added too much heat for around 10-15 minutes at 160. I'm thinking the pack that didn't swell was bad, I screwed up the starch conversion with the high temp, or I'm being way to impatient. Planning on taking another gravity reading on Monday. If its stuck at 1.050 what should I do?
