Hey guys, don't know how, but Orfy's re-done hobgoblin thread is nowhere to be found. Anyhow, back to the point. I did my first AG using Orfy's recipe but accidentally added in an extra 1/2 lb of Marris Otter (11 lb instead of 10.5) Not sure what my efficiency was but I followed the rest of his measurement to the 1/10th of an ounce. My concern is my OG ended up at 1.066. Would this be due to the extra grain or do I have some other issue? My girl was "watching" my boil for me and Even managed to let it boil over about 20 oz or so. I was expecting to end up a bit low as a result but this doesn't seem to be the case. Any input?
