One thing I've learned in almost three years of brewing, it's a constant learning process. Today I learned that I don't need to add salts to my already good tap water. I've been doing it for the last several brews, and my efficiency has been crap. Mashing on my House IPA this morning, and didn't use them...gravity at 40 minutes into the mash a very nice 1.065. Since I kinda overdid it on the strike water (I like a thin mash) I should wind up with a Double IPA out of it. Also running the recirc pump at full blast rather than ramped down, seems to me it should pull more sugars out and it is. It's a great brewday!!!
