Check out this video. I noticed this odd fizzing/bubbling/gurgling activity from the sight glass fitted on my conical dump port 1-2 hours after filling it with wort and pitching with dry yeast. It hasn't been long so I would be surprised if it was fermentation activity starting already. It's since been 24 hours and still bubbling like this. Any ideas what could be the cause? I thought it might be a leak in the bottom dump valve letting in air but doesn’t quite look like that's the culprit. Maybe hops from the trub giving off CO2? I did a normal all grain IPA brew inc whirfloc. It is my first time fitting a sight glass so not sure what activity is supposed to be going on there or not. Thanks!
