On Saturday I brewed my 2nd all grain batch, a sasion. I used an oxygen wand for the first time and pitched Omega Yeast OYL-500. It’s a 5 gallon batch and the temp has been between 68-75.
My basement smells like fermenting beer; however I don’t see any activity in the airlock. Not sure if I should be concerned because of the lack of airlock activity?
Airlock activity isn’t always an accurate indicator of fermentation. Fermenting in a bucket? If so, the lids (especially after several uses) have a habit of not always sealing well. If you’re smelling beer fermenting, it probably is. Make the hydrometer your friend - check gravity in a few days and see where you’re at. Being a saison, remember that most saison strains eat through the vast majority of sugar within a week or so, but are pretty slow to reach actual FG. I give my saisons 3 weeks and am generally at FG by then.
You know you’re at FG when 2-3 readings are the same, checked a day or two apart each. Good luck!
I don’t know if you guys keg, but now and then I’ll dip a q-tip into some keg lube and run it around the rubber seal in the bucket lid, much like you’d do on keg o-rings. That and plenty of pushing down around the lid helps.
