Co2... thats it. Never made this much at once before. It hit me like a ton of bricks.
Its in a basement with not much air movement. Its looking good so far. I got nervous because I tried a different way to pitch yeast. Took a bottle of water, dumped half, dumped yeast, shook, waited 5 minutes, shook like mad till I got tired, waited 5 and pitched into carboy. Seems like it worked good.
