this is the 3rd batch I have brewed and I always get bubbles in the 1st 12 hours. It has been 36 hours and still no bubbles. Help what should I do now? I used a dry yeast in warm water. the batch is a rasberry wheat with a hint of chocolate malt
I would check for krausen (foamy head) on your wort...if it's there you're fermenting and either haven't built up pressure yet, or you have a leak. If there's no krausen I would seriously consider repitching.
Is this in a bucket or a glass carboy? You may not have a good seal. If it's a bucket, press lightly on the lid, you should see the water move in the bubbler. Also, have you kept the temperature about 70F? The yeast growth stage requires higher temperatures than the fermentation stage.
Press down firmly, and then push the edge of the rim in towards the bucket. That's what I have to do with mine. Also, make sure your lid has a rubber gasket in the rim. A friend gave me a bottling bucket/fermenter from his experiments some years ago and it doesn't have a rubber gasket in the lid and won't seal for anything. It's only useful for bottling.
I have bubbles, I went and got a new lid and repitched just to be save. Started getting bubble within an hour. I hope no damage was done while changing lids. thanks everyone for the help. yes, rebubula is a moe. reference.
