Its been 12 days of my turbo cider brewing so as the popping is only 1 an hour, I decided to test it using my hydrometer for the first time. I filled the tube and the reading is 80? This is as far as it goes, I didnt take a reading at the start so I haven't a clue what the alcohol percentage will be? If its now ready, how much sugar should I prime with for 21L going in a basic non glass pressure barrel? I like it abit fizzy, also, why is it quite bland? Its a touch sweet but bland? I used the usual apple juice from lidl, medium cider yeast and some tea.
