problem or not

I am making a milk stout of 1052 and pitched a 1 liter starter of 1099 Whitbread yeast on Monday. Bubbling in airlock great on tues and wed morning nothing this morning. it just quit, should I let it go another day or two before taking specific gravity or pitch more yeast.

 

What temps are you fermenting at? If you are fermenting warm it might have finished already.

Sounds like you are using a bucket, those tend to not seal around the lid very well, CO2 could be escaping that way rather than the airlock. I think your best course of action would be to wait a few more days, take a gravity reading, wait a few more days and repeat. If your gravity is stable, it's done.

You can't count on the airlock to show you when fermentation is done. Only time and gravity readings.

 

+1 on can't count on the airlock. I don't think I'd even worry about it - I'd just check gravity twice before bottling to be sure it's done. I'm one of those that don't like to open the fermenter if I don't have to.

 

Agree with the posters above. One of my buckets almost never seals completely.

 

Airlock activity is not a good gauge of fermentation. Take gravity readings until they are stable then proceeded with your recipe
