I brewed my first stout 3 weeks ago and had an expected OG of 1.055 but what I measured was 1.044(with temp correction)... This was an extract recipe so it wasn't just poor efficiency. Today I checked and the FG is holding at 1.026 which is quite a bit higher than the expected 1.015 estimated by my recipe calculator. I dumped the wort @ 60F right onto the Nottingham yeast cake from the previous batch and it took off right away and was done within a few days. I allowed the temp to raise to 68F over the first week and kept it there. I've checked the calibration of my hydrometer and it seems fine. I did add 8oz of lactose but that doesn't seem right that it would be 10+ points higher. It just seems weird, especially when all my other batches have been within a couple points of the recipe calculator I use. Any ideas what is going on with this batch?
