I am brewing an Irish Stout from a Midwest extact kit. I am using dry yeast without a starter. i didn't take a reading when I started but it was suppose to be around 1.042-1.046. The temp is 69-71. Started fermenting within a day and went good for a couple days. Then it just stopped. I have been taking Hydro readings and it hasn't changed for 5 days and is only at 1.028. This brew is suppose to finish at 1.010-1.012. What advise does everyone have for me?
