This is my first ever time brewing beer. I was given ,as a gift, a complete starter pack from the website balliihoo. I have attempted to brew my own larger from a kit called 'Geordie Larger'. It is a 40 pint kit and I have followed the instructions to a tee. I used Vinclasse brewing sugar throughout the brewing process. I have now left the beer in the pressure barrel after adding 70g of the brewing sugar ,as told to on the instructions, for 2 weeks and when I have gone to taste some the beer is completely flat. I am confused on how I could re-carbonate the larger. I had the pressure barrel stored in the ideal temperature and lubricated the seals ,as I was told to do on a youtube video I watched, but my beer has no fizz what so ever. It comes out with a bit of a head but I think that's just the pour. I was just wondering if someone come help me and save my beer!
