So you have added the yeast 2 days ago and the airlock still isn’t bubbling. Check the common problems and solutions below to this issue.
Note: The only true way to confirm if your brew is fermenting is to take a sample and use the hydrometer. This will show if there’s activity as the reading will drop each day.
If your airlock isn’t bubbling it may be due to a poor seal between the lid and bucket or around the rubber grommet in the lid. The brew may be fermenting but the CO2 is escaping elsewhere and not coming through the airlock.
Ensure the lid is sealed tightly all the way around and the rubber grommet is fitting snug with the airlock pushed well into it.
