Hello, I hope I'm posting this in the right place! I brewed my beer last saturday and I completely forgot to measure the OG with my hydrometer. I realised it 4 hours later and decided to measure it but there was already Co2 in it so I got as OG 1.080. So now my question: Is the measurement completely false or can I keep the 1.080? Or 1.070 because of the Co2? Thanks for any advice! Sry for my not so perfect english, hope you understand what I mean. :?
