I followed the all-grain recipe from page 98 of "Beer Captured" to the letter yesterday, yet recorded an OG of 1.047 instead of 1.059 as listed in the book. The ProMash program listed my efficiency at 79%.
I'm new to all-grain brewing (about 5 batches so far). My questions:
1. Would the OG be affected by the use of filtered water during mashing/sparging?
2. Is the target OG a ball park figure? How much deviation is acceptable?
3. What are some of the factors that can affect OG?
