Any ideas what is going on?
You don't say what your batch size is. However, if your efficiency is 70% and I assume the batch size
is 6.4 gal, and I ignore the amount of crystal malt, the points should be:
(11 * 46 * 0.81)/6.4 * 0.70 = 45 points (i.e. OG = 1.045)
Which is what you're expecting I believe. If I'm right, I think you may have confused batch size and boil size. Perhaps you wanted the batch size to be 6.4 gal instead? Batch size is how much you want to end up in the fermenter. Boil size is how much wort is in the kettle at the start of the boil. To move the calculated batch size up or down, you must edit the boil off rate in the equipment record you have associated with the recipe.
Hope this helps.
