should i ideally be sparging for an amount of time (i.e. 60 minute sparge) or taking gravity readings and sparging to a specific gravity? if the recipe does not specify what gravity should i be shooting for? thanx!

Do you mean the recipe does not state an OG? I guess that would not be too surprising as it would need to be stated with an assumed efficiency. The recipe author cannot tell you what efficiency you should expect to get. But often with an AG recipe an expected OG is stated with a presumed efficiency. E.g. in BCS, all recipes assume 70%. It would be a good idea to record your pre-boil gravity and volume, then calculate what efficiency you get so that you can dial-in your process over time. Anywhere between 70% to 80% efficiency is pretty decent.
itsratso said:actually being new to this i don't really know if there is a difference between the pre-boil gravity and the OG. so are they the same? most recipes i have seen have the OG listed. so if i have a similar assumed efficiency then the OG is the target gravity (if not just using the time method)?
Oops! Meant to say that I take a preboil gravity reading after I've hit my preboil volume, not gravity.

mash till the iodine test is good,,, (screw time)
sparge till you get what you want in the boil kettle
and f%@k the numbers
