Hi.
I brewed my second batch a couple of days ago. Last time I brewed, the morning after, the airlock was bubbling like crazy. This time, it's been a day and a half since the yeast went in, and still no bubbles.
There are some major differences between the two brews that might help explain the difference:

I brewed my second batch a couple of days ago. Last time I brewed, the morning after, the airlock was bubbling like crazy. This time, it's been a day and a half since the yeast went in, and still no bubbles.
There are some major differences between the two brews that might help explain the difference:
- Pitching: last time I made a "starter" - mixed the dry yeast with preboiled water and sugar, and let it sit for about 45 minutes. This time, as per the recommendation from the owner at the brew shop - I just poured in the dry yeast.
- Batch size: last time was 20L, this time it's two batches of 4L.
- Yeast per wort volume - last time I used one packet for 20L, this time I used one packet for the two batches, so half a packet for 4L
- Temperature: last time I did the whole thing at room temp, which was about 20C (68F), this time, I cooled the wort to 16C (60F) prior to adding yeast, and I also keep the fermenters in a cooler with water at about the same temp (adding ice every now and again)
- Timing: last time I used extract, so I just cooled it with ice and immediately pitched yeast. This time I used BIAB, so couldn't cool like that, so I cooled partly in a tub, and then put in the fridge (in an airtight pot), and added yeast the next day.
