Quick question, as I have not seen this info posted anywhere before:
For a correctly calibrated hydrometer to register 1.000, you must use distilled water ( I get 1.004 in my tap water). But since I BREW with tap water, shouldn't I be subtracting .004 from the readings in my beer?
I assume that all those minerals still make it through the mash, sparge and boil into the fermenter, right?
