I have been using this site for a while now but this is my first post. I recently brewed a light blonde ale to kick off summer and had what i thought appeared to be a stuck fermentation. My OG was 1.047 and it stuck for a few days at 1.020. I used safale us-05 dry yeast so i don't think under pitching was the issue. I don't have a fermentation chamber so my guess is it may have fermented too hot? Anyways, to try and get the fermentation to complete last night i put dry yeast into a galss carboy (didn't re-hydrate) and racked the wort out of my primary bucket onto the yeast. This morning, there is a ring or halo of particles suspended about an inch below the surface of the wort around the edge of the carboy. It kind of looks like granulated yeast. Has anyone encountered this before? I use StarSan and am diligent with sanitation so I am hoping its not an infection. I will try and upload a photo when I get a chance. Thanks everyone!
