Quick question, I just brewed my first batch of beer last Wednesday night. I learned a lot of things just from that first batch, and hopefully won't repeat the same mistakes twice. But one thing I did wrong was pitch the yeast before taking the specific gravity. Does this really matter. I took the S.G. about 2 minutes after pitching the yeast. Of course the even bigger mistake I made was that I didn't write the S.G. down.
I'd appreciate any advise for the beginner. Thanks.
