Hi everyone, I have a brew entering its second week of secondary fermentation in a king keg with the top tap system . I wanted to see what it was like so turned the tap but only the gas escaped and to my dismay, no beer! Turns out I had put the float round the wrong way. ( Don't drink too much beer whilst kegging! ) So I rectified the float and topped it up with some co2. Beer is now flowing. Hallelujah. Unfortunately the beer is completely flat now. I'm worried it's not going to carbonate enough. Should I add some more sugar or has that boat sailed already ? Or do I just suck it up and hope for the best ? Any response gratefully recieved. Thanks.
