I have a question, I just did a brew with Northern Brewers Caribou Slobber. My OV came out at 1.050 not 1.053. It dawned on my that this is the first time I used an areation stone. After 20 minutes of pumping air in the fermenter, I dropped in my tilt 2 and then pitched the yeast. Wouldn’t the air in the wort lighten my OG? Making it lower?
