Hello HBT community! Long time reader, first time poster. I have been researching home brewing ad nauseam for the past 3 weeks and learning everything I can before I begin. It already sounds like this will be an amazing hobby/adventure and I am looking forward to making my first all grain brew this weekend. I have a 5 gallon equipment kit already, but further reading and personal preference have led me to start with smaller 1 gallon batches; my kit from Brooklyn brew shop arrived yesterday.
I will likely be employing a modified BIAB along with their directions to help further cut down on rogue particles in my wort, but my specific sparge question is this: with the rinsing of the mash/grains (which will be in an open mesh bag on a strainer), they are saying run the wort through 2-3 times... Should the last time through be with clean water heated to 170? Or will it be ok just to run the wort though with no final clean wash.
Thank you so much in advance - I know this will be a great learning experience. Happy brewing!
