Default Fermentation issue

Hi everyone, fairly new to brewing. The last four batches I've made have had no bubbling. Fermentation is happening. Krausens are forming, gravity readings are changing and good beer is happening but I can't figure out why there are no bubbles. I have a few theories and I was wondering if anyone would have input.

I use 6.5 gallon bucket for five gallon batches. Is the extra space just accommodating the gas produced? The water in the air lock shifts with pressure changes but no bubbles. My other thought is that the seal isn't secure. Last time I taped around the lid but no change.

If it doesn't matter I'll just leave it alone but if it has the potential to affect my beer and prevent me from making the best beer I can I want to figure it out.

Any input would be welcome, thanks in advance.

I've mad an amber ale, a gluten free amber ale and two pale ale. I've used Safale US-05 yeast for all of them since it's temp forgiving. It ferments at about 70-72 degrees Fahrenheit.

It does not matter, please do ignore the airlock, gravity readings are the only accurate way to determine what is happening with your beer, wait until you think it is done, then take a reading, then wait another 3 days and take another reading, if it moves, wait another 3, etc.

The easiest and best way to make great tasting beer is to have patience.

I've only done partial mash kits from BrewersBest , 2 India pale ales , 2 imperial pale ales and and my just brewed their imperial nut brown. All the ales came with that US 05 that your using and they fermed hard and heavy for around 3 days , and 1 bubbled steady for 9 days ... The nut brown ( that I've got many replies about on here , thanks HomeBrewTalkies ) I noticed next to no fermentation ... I was wondering if

My first batch I used a bucket similar to what you're talking about, and I thought there was a good seal on it. I was wrong. It fermented fine and worked out well, though not a single bubble was ever visible. It's remarkable just how sealed fermentation chambers need to be. I'd say, you're all good.

Regarding ifearnothing0 (except stuck fermentation!), it could very well be the characteristic of the yeast. Some yeasts make big krausens which are sometimes so gross you think something's wrong with the fermentation only for them to eventually slip away and fall out. Some yeasts make hardly any krausen at the top, or if they do, it's so brief you may miss it. Do some research on the yeast strain you used, because you might find that it often shows little evidence of it's work on the surface.

I would send a PM to Revvy with your question. He is usually pretty good at diagnosing problems relating to the absence of bubbles.

If you're not seeing bubbles, it means that the co2 is leaking out someplace instead of going through the airlock. It doesn't matter a bit, though, so put the lid on tight and put the airlock in and don't give it another thought.
