I have been extract brewing for about two years and have had great success, so I decided to graduate to all grain. My first batch, a dark lager, turned out great. I am using beersmith and the OG was a few degrees below the predicted OG. Being my first batch I wasn't upset. However my second and third, an IIPA and oatmeal stout, were about 20 degrees below. Not good. I did have to create an equipment profile because the setup I was using for my last two weren't on a default. I'm using a ten gallon cooler and ten gallon megapot 1.2. I have a few theories on why those didn't turn out as great. So I have two questions, 1. Any other thoughts on why those didn't turn out so good and 2. If you are proficient with beersmith and/or are using the same equipment, what do you have the information set to?
