Thanks for the info. My intended OG was 1.061. My actual was 1.040. I believe I used too much water for the mash. Grains were 14 lbs and I used 5.5 gallons of water. I think it was the new math that screwed me up, not age.
I talked to a brewer about 1 hour ago and walked me me through...
I brewed an all grain beer yrsterday. My fault. My question is, "I have the wort in a fermentation vessel in my cooler in order to bring the temperature down to pitching temp. Is it possible to make a batch of wort using water and dme to make up the lost gravity points before I add the yeast?
