I'm a new brewer, about 10 batches, last 3 have been BIAB. I did a Kama Citra and got the mash too hot-160 and ended up with unfermentable sugars. O.G .045 and F.G. .020. Let it sit for almost 4 weeks in the fermenter. The final week saw no change in the gravity so I bottled. 5 oz. of corn sugar...
