I started a fresh wort IPA kit a week ago from ND Brewing. I have had to pitch a yeast in to it twice and I still have nothing coming from it. It was about 24 degrees when I pitched the first one, 22 the second time about 4 days later. I'm not sure if the wort is off or has a use by date but I have no signs of fermentation at all. My hydrometer reading is constantly 1012. Can I fix this somehow or is it shot and I should throw it out and start again?
