Dont feel bad. My first batch was a partial mash. Scorched the extract, and missed my final gravity. It tasted like half water, half heff after carbing!
2nd time was revenge on the first, or so I thought. Only this time I went all grain. I wound up missing my mash temp, oversparging after mysteriously getting too much liquid from first runnings and not correcting sparge amounts , plus missing final gravity. Once again half water/half wheat beer.
On the bright side of all this, I will not be making the same mistakes again and have corrected problems in what I did. My third batch is coming up, and everybody around my place thinks I suck at brewing LOL.
The most important thing is to not give up, and learn why things went wrong and correct for next time. I feel just exhausted at the end of the brew day, and i feel like throwing in the towel. I think part of it is stress making it harder, because there is a lot to remember and you dont wanna eff it up.
Dont throw out your beer, let it age and taste again. From what I understand unless it is heff, you want it to age to mellow things most of the time.
