So basically i forgot to take an OG reading. Its only been a little over 24 hours so i decided i would take a reading. I'm new to home brewing. I took my sample by using a measuring cup. I let the cup soak in warm water with a bit of bleach and then rinsed it. I noticed krausen already forming on top. So i scooped up some of the brew to test. The krausen started to disappear. It almost appeared to be flat again.
My questions are, was it ok to use a measuring cup? It has a handle so i figured it would be alright because i'm not touching the beer.
Also, the fact that the krausen kind of disappeared makes me wonder if i had done wrong and possibly contaminated the batch?
It did taste nice though
