My system has an efficiency around 67%. I normally hit my OGs regular (1.060 and lower) beers. I've made a few big beers and have come up at least 10 points short of my expected OG. Using the breakfast stout I made last weekend as an example, I was expecting an OG of 1.085 and got 1.075. It's just weird to me that I hit my OGs on normal beers, but come up short on big beers. It almost makes me think that the mash liquid can only take so much sugar.
