Was on my 3rd ever brew today and not going to lie, I think I got a little bit cocky. My first two went over really well (process as well as tastings) so I figured I had this thing down. Things started to go downhill when I panicked at my LHBS when they didn't have the grains I wanted, so I tried to make some quick substitutions and ended up getting too much and not enough of a few, pushing the color and gravity out of style (Irish red). So made the trip back today and got what I wanted, but turns out when the hops packages say "2 x 1/2 ounce" it means you're only getting 1oz of hops, not 2.5oz like I needed. With SWMBO rushing my process, I didn't notice until it was too late...
any who, to make a long story (too late for that too) short, I'm way behind on my IBUs. Can I just go shopping say tomorrow, buy the correct amount of hops, boil them for alpha acid extraction and add it to my fermenting wort? I feel like I'm grasping at straws here, but figured it could work. I realize the contamination risk is increased, but I'd rather take the chance. Otherwise, it's going to be some SWEET (literally) beer for St. Patty's Day. Thanks for any advice
