Hi everyone, I am very new to home brewing I started a cider kit called John bull I followed the instructions for a 40 pint batch. After 8 days isaw no sign of fermentation so I took a hydrometer reading it was at 1.000 the next day I took another reading it was the same so I bottled the cider and used carbonation drops. I set the 40 pints in my back room. I got called to work away from home for 6 days it got colder here and when I got back at weeks end the back room was about 10-12 celcius. I brought the cider into the war to try and get the secondary fermentation going. After a week I put it back in the cool. It's now been 3 weeks since bottled. I tried one tonight and as soon as the top was twisted off I could smell yeast. I tried it anyway and it tasted of yeast ( go figure) is the cider ruined any suggestions are welcomed please help.
