I am new to cider brewing (my first batch has just started fermenting). As I'm new and just want to trial the process before getting into something more involved, I used store bought juice (no additives etc).
I got myself a hydrometer, and have measured the OG (1.049) and understand that I will need to measure the FG to calculate the final ABV.
My question is this: if I need the FG to calculate the ABV, how does one predict the final outcome? Is the OG any indication of where you'll end up?
I didn't add any sugar to my batch, so worried the ABV might be too low?
Also, when I start my second batch, I'd like to aim for around 10%, so unsure how to work out how much sugar I should add to reach that volume.
Thanks in advance!
