I'm just getting back into brewing after a 2 year hiatus and want to get more serious again. Today I started my first 5 gal batch of my Speckled Cow Recipe (a spotted cow knockoff). The original recipe I copied from another brewer called for a 10 min sparge. I am a BIAB brewer and from what I understand, sparging is intended to help rinse the additional sugars off the grain and keep it in the mash (correct me if I'm wrong here). In my garage, I'm fortunate to have a constant pressure pumping system at 70PSI coming out of a hot water faucet that gets to 120F and I have a small hose attachment with a pressure nozzle. I timed the pressure nozzle and figured out how long it took to get 3.3 gallons of water (what I needed for sparge). Question 1) Is it OK if I have my wife spray the hot high pressure water over the grains bag while I hold it to act as the 'sparge'? Question 2) I have millled grains that are about 2 years old but have been stored in ziploc bags, are they still good to use? I'm not a real picky beer drinker, just want a flavor close to my original recipe. Question 3) I have an 80 qt kettle that I want to start using to make 10 gal batches of this stuff once I get the recipe down. It has a bottom tap to drain, but I've never used the thing before. The problem I have is A) That kettle is heavy as hell when it's full of water/mash, what type of setup have you seen that can lift this high enough to be able to use the tap and gravity to get the wort out? I'm sure I'll think of more questions as you guys help me out, thanks in advance!
