Scottish Heavy... Fermenting for a week, started great, but really only very active for a couple of days. Looks like I had it at 74 degrees, ideal range 55-70w/ the yeast (which I had in a starter originally). Very little activity now. If I get it cooler, should I see it restart or should I just be doing hydrometer readings periodically... Think it should be in primary at least another week... But advice welcome...
