All Grain and 8 inches

Did my fist all grain batch on Wednesday and right when I put the kettle on the burner is started snowing. We go about 8 inches overnight. Everything went great and I only missed my target O G by .001. I broke up my sparge water into 2 batches and the runoff was still well above 1.010. I was wondering if it would have been alright to sparge again even though I had already used what beertools said to use for the sparge water? Just boil a little longer to get to the 5.5gal volume?

Wow, Palmer. That's crazy. I grew up in Wasilla and Eagle River. Definitely don't miss those early snow days.

Your sparge amounts are minimum water usage considering enzyme dilution and boil time. I personally don't think that using more water will necessarily hurt your brew but at the same time, I don't think you are going to extract enough sugar to make the extra boil time worthwhile. Either way, I would be interested to know what your results are. I never measure efficiency anymore, I just take what I get and that always makes good beer.
