OK, well. first grain brewday overall went well. There were mistakes for sure, but they weren't huge.
Biggest one was pH, perhaps my overconcerrn about pH and trying too hard to chase it and messing it up with a combination of a miscalibrated meter and bad decisions. Smaller mistake was completely missing one of my hop additions. And then doing a 15 minute hopstand, for the hops that I didn't put in lol.
But my efficiency was off the chart, at 93%, meaning my Cali Common is gonna be about 6%. The colour is also completely wrong, a dark brown instead of the coppery amber it's supposed to be, but fermentation went super well, from 1.054 to 1.012 in about 4 days, and it already tastes good, even with all the extra acid I had to add to the fermenter to get the pH to a remotely sensible level.
it's not right, but the next one will be a lot better thanks to it, and it's going to be very drinkable, so yay, win/win.
