My last partial batch used Laaglander extract (I thought it was Munton's, which is what I usually use). I hit my predicted OG dead on, but after three weeks, I was still about 12 points above my calculated FG. I didn't understand it at first, because I had a good strong fermentation. It was at that point that I discovered I'd used the Laaglander extract--it's notorious for its comparatively low fermentability.
I didn't really have a problem with the higher-than-expected FG, but I would have liked to have known this before I brewed the batch. As it is, the program only has one "generic" extra-light dried malt extract (and other extracts, for that matter). I was going to make duplicates of that "Grain/Extract" entry, and then change the fermentability of it to match my FG (predicted FG was 1.017; I ended at 1.028 instead). I discovered that none of the options under the grain/extract parameters allow you to change this. I don't plan on brewing with extract much longer, but for anyone who does, this is good information to be able to change. I've found resources that list Laaglander's apparent fermentability as 55%, while Munton's is closer to 75%. Any possibility of this?
