I wouldn't be too concerned by it but just be sure to keep up with the gravity reading to check for real progress. That's the surefire way to make sure your beer is doing what it's supposed to. Airlock activity isn't the only sign.

Airlock activity is not the be-all end-all. You could have a bad seal on a bucket or on the airlock grommet itself. Give it a little time (3-4 days) then check the gravity. Gravity movement is really the only 100% reliable way to test if the yeast is working.

With Kvass you don't want to wait longer then 3-4 days. In fact, all your fermentation should be done in 1-2 days in a warm place, that's why you don't really wanna go above 4%ABV. Then it should be cold-crashed for 1-2 days, filtered and consumed within another 3-4 days... It should not take longer then 7 days from making Kvass to finishing a last pint of ...

No way to really know. For sure it will be more oxidized. It will be a flaw in taste, but no one can know how big one. Real danger is with flood. Flood promotes mold, and other bad microorganisms. We can't know if some is in your wine, and how much alcohol was there when it got contaminated, if it was. Worst case? Little alcohol, sourness, "toilet" taste, ...

As the previous posters mention it sounds OK just a bit of a slow start. If after 48 hours you are still concerned, take a gravity reading and if it has not noticeably dropped, then re-pitch a new starter.

Sounds like everything is doing fine. 8 hours of lag time isn't bad at all. Extra headspace has no effect on actual fermentation and little effect on air lock activity, though c02 does slightly fit in between molecules in air as it mixes, it's so small it's only a matter of note for novelty.

Fermentation needs lots of oxygen. What I usually do in my 10 l batch is to shake my fermentation vat to add more oxygen to the wort before pitching the yeat and put the air lock on the vat. I assume you started your yeast before pitching it. I once did not do that and sprinkled the dry yeats over the wort as per instructions on the package, however, it ...
