Brewed my first all grain yesterday. Started with an ESB that looked good. All went well except that I ended up with 3.5 G of wort instead of 5. My OG was way high due to this. After researching, I added 1.5 G of water to it when going in the fermenter, hoping I was ok. I was super relieved to wake up to the fermenter bubbling away. Hopefully this turns out good. All is well so far.
