So I've done 4 5 gallon batches of BIAB, and I think I have it down pretty well. Getting efficiency between 72-75% on beers up to 1.065. I recently made a RIS, and my efficiency suffered, as it does with a larger grain bill and BIAB. My question with the attached recipe is why was my estimated og so low? When I look over my other recipes, it's usually no more than 10 points lower/different. It was estimated at 1.058, and I got 1.071.
