So, first off, hello everyone. This is my first post and I don't really ever use forums so I apologise in advance if this is in the wrong place or has already been covered somewhere. So, I just bought my first recipe the other day and the basic equipment to start. I decided to try an IPA and I followed my recipe with no problem. When I got to the part about adding your yeast the instructions gave me several options. It talked about pitching your yeast but it also said that you could just add your dried yeast to the wort which is what I did. Added the yeast to the wort at around 83°. I also aerated the wort before hand by pouring it back and forth between two sterilized buckets. I noticed it bubbling after the first day and it sped up by day three to a bubble every 2 seconds or so. On day three I bought a hydrometer and opened it back up to take a reading and noticed on day four that It was barely bubbling. I have tried reslealing the bucket repeatedly thinking it may have been a leak but it hasn't changed. The area I was storing it at was about 61° so yesterday I moved it to a new area (66°) thinking maybe it was just to cold but there is still barely any activity. So my question is, should I try pitching new yeast and adding it or could it just be a leak in the lid? Or could fermentation be complete?
