    Made a scotch ale mashed @ 156-158 started 1.065 ended up with 1.021 safale 05 yeast which is usually aggressive. Doesn't have a really sweet taste from residual sugar. I was expecting a 1.014 any ideas?? I had a 1# flaked outs, 1# brown sugar and toasted 2# of 2 row.

    Are you sure it is done fermenting? Might need to rouse the yeast by gently stirring and raise the temp to 68-70F.

    What temperature was the fermentation at (any dips)? What is the batch size, and how many packs did you use? High gravity beers call for more yeast.

    That seems like a high mash temp range if you are aiming for strong attenuation. You likely ended up with lots of non-fermentable starches, as the beta amylase necessary for converting the starch to simple glucose and disaccharides is denatured in that temp. range. If you want higher attenuation, use a lower mash temp (around 150-152) next time.
