It has been a little over a week. The Windsor yeast stalled out at 1.040. I am not totally sure why. I pitched 1 pack for 5.25 gallons. It is supposed to handle 1.070 wort. I roused it up last Friday by lifting the bucket and swirling it around. I also raised the temp to 68. Sunday, it was at 1.039. It tastes fine, with no off flavors. I don't think I under pitched.
I have another idea about why it may have stalled. When I doughed in, I know I misread the temp on my kettle thermometer. The water was 10 degrees high (one of the reasons I like brewing electric, set it and forget it). I didn't realize this until I looked closer at the round thermometer on the kettle. The initial mash temp was at 165, not 155. I recirculated and it took 10 minutes to get it cooled down. I am afraid the higher mash temp may have messed with some of the grain enzymes during the initial mash and now I may have a lot of unfermentable sugars. I have posted this on other boards and some people have said that 10 minutes at the beginning may not matter. I am not sure. I am just thinking that when mashing out you heat to 165 to stop the enzymatic conversions.
Anyway, with nothing to lose I decided to add some more yeast. Yesterday I made a small 1.030 starter with a pack of Nottingham. I did this so the yeast would already be going when pitched. I added it this morning. Time will tell.
