Starting point was this recipe: www.homebrewtalk.com/showthread.php?t=248332

Was our first non-kit attempt. Converted it to an extract brew and accidentally reversed the hop schedule (all at FO instead of at the beginning of the boil). But everyone liked it that way, so we kept it!

Mash Schedule:
Strike grains with 6.75 gal of water at 165 °F.
Mash at 152 °F for 60 min.
Vorlauf and lauter 4.25 gal in your first runnings.
Add 4.25 of sparge water at 168 °F.
Rest for 15 minutes.
Vorlauf and lauter 1.75 gal in your second runnings.
Your combined runnings should be 6 gal.

Hop stand after FO for 15 minutes.
