Hi everyone, 1st timer here! just wondered if anyone could please help me out? i'm on my 2nd batch of homemade wine,the 1st turned out fine,taste's great and is as clear as anything so.. i thought ok this is going great i'll start my 2nd batch,the first time i forgot to take a sp reading so im unsure of the %,this time i remembered i started with a reading of 1080 and now it's reading 990,can anyone tell me if i'm working the % out correctly? my calculation has ended up with a 11.6% which i would be very happy with lol,many thanks in advance
