actually - just did a bit of reading there and it's answered my question, basically bubbling isnt a good indication of whats going on - cool, was getting worried!

I had the same question a few weeks ago when I started my first homebrew.

It's normal. If your seals are all good, the presence of vigorous bubbling means fermenting. It more or less stops bubbling when active fermentation is over. The next step is to give the beer a little time for some of the yeast to drop out of suspension.

This thread kept me going after no real signs of fermentation after 48 hours. This is my first brew (since one kit 16 years ago) and I did a full boil. I have an IC but was not prepared for the wort to take just over 2 hours to cool and I had rehydrated my dry yeast way early.

I thought my yeast had sat out for too long. I thought my airlock wasn't tight enough.

AND THEN TODAY IT WAS GOING OFF LIKE A ROCKET! Full krausen and bubbling every half second. I noticed this at like 68 hours after pitching this am so it was probably active sometime over nite.

Be patient fellow noobs! My 60 min IPA is ALIVE!!

I've got my fourth home brew batch (pumpkin recipe I made up) in the primary now. Been in there almost 72 hours now without a single bubble out of airlock the entire time. I've read that the airlock shouldn't be relied upon to gauge if fermentation is happening, so I peeked in through the side of the lid and saw this...

Attachment 146107

It appears that I may have fermentation taking place, but not sure. I used 2 packets of Safale US-05 dry yeast in the 5gal batch, rehydrated it, and pitched it once wort reached ~75degF, and have maintained at ~68degF since. But I forgot to aerate wort and didn't realize it until the 48 hour mark. Would this be causing the lack of bubbles out of airlock? I've checked the lid seal, no leak. I will check the gravity this evening at the 72 hour mark. Any advice on whether I should pitch more yeast if gravity has not changed? Thanks.

brewbee74, that attachment isn't coming through for me. can you upload using something like imgur?

i would guess that 2 packs of rehydrated s-05 pitched into 75 degree wort may have already finished fermenting. that's a whole lot of yeast

can you take a gravity reading?

I'm curious how you checked the lid seal.

One tip to check your lid seal is to gently press down on your bucket lid. If the lid is sealed, you'll get a bubble or two out of the airlock.

I bought a brand new bucket and it didn't seal properly. My trusty 7 gallon that I bought 9 years ago still seals like a champ.

progmac, here's another attempt at including the image. Let me know if it works. It's just not producing the volume of krausen I've experienced with my previous three batches (not to mention the lack of bubbles in airlock). Just took a gravity reading. OG was 1.062, it's now at 1.020, so it's looking promising. Maybe I'm just paranoid.

Bleme, I used the method uatuba mentioned. I pressed down on lid, causing a bubble out of the airlock.

Every fermentation is different. I've even split a 10 gallon batch into 2 buckets, same yeast, same temperature, and they turned out noticeably different.
