i know this has probably been asked before but i couldn't find it. my friend and i brewed his first batch (my second) on feb 1st. while sanitizing, my hydrometer broke. being that it was sunday, we couldn't go buy another at the beer store so we just went with it. he left while the wort was cooling and i couldn't get ahold of him so i dumped it into the fermentor and closed the lid. anyway, we only have 4 gal in the fermentor and i would like to know if i should add water until i get to the fg before bottling or just have a strong ipa? i know this has probably been asked before but i couldn't find it. thanks.
