I'm brewing my third ever batch, and it's single hop recipe I was given by a neighbor that brews and grows his own hops. He gave me a big bagful recently that I've dried and on Sunday I made a 5 gallon batch with this recipe. Everything went smoothly, I'm fastidious about keeping things sanitized so I'm not worried about that.
I have a little tip someone gave me where after I pull a sample to test jar to take a gravity reading, I keep it in there, covered, so I can see what's going on in the bucket. Cheap alternative to a glass carboy I guess. The sample in the test jar is clearly fermenting, bubbling away nicely. The fermenting bucket however, no sign of bubbles in the airlock and it's nearly 48 hours since I pitched the yeast.
I opened the bucket to see if there were visible signs of problems (what, I don't know) and noticed that all the hops had gathered at the top, so I just left it.
Question is this - is it likely the wort is fermenting but the hops are trapping the Co2 as there's not a lot of it to 'push past' the hops yet? I'm wondering if I need to repitch the yeast.
Thanks in advance.
