Thanks everyone... This is helpful. I was planning to mash between150-160 and add the rest of the water at 180 (per the show anyway) after an hour. I will pour off and recirculate the wort too. I have been doing extracts for about 6 months and look forward to trying the all grain process.
I am attempting my first all grain brewing session, and had a question on sparging process. A recent episode of "This Old House" showed a home brew method where the mash is done as normally described... but after an hour, more hot water is added to the mash and after 10 minutes all the wort is...
