View Full Version : 3 gallon Lalleman Abbaye Cyser BOMM fails to start ferment

01-16-2016, 11:21 AM
On January 12, I made up a 3 gallon batch of Cyser BOMM using Lallemand Abbaye yeast. Just scaled up by 3X the 1 gallon Cyser BOMM recipe and used Abbaye yeast instead of Wyeast 1388. Have successfully made a 1 gallon Abbaye Cyser BOMM previously.

The O.G. was 1.092. Rehydrated yeast using Go Ferm protocol. Room temperature = 65 F

Degassed every day.

1/13 S.G. = 1.092
1/14 1.092
1/15 1.086
1/16 1.086

This appears to be a failure to start fermentation. EDIT - can see a small amount of CO2 generation (bubbles rising to the top).

Is it time to pitch another packet of Abbaye yeast? Should I just use the Lallemand Abbaye yeast rehydration instructions this time?

Did you check your pH? Did you atemperate?

No, did not check pH. BOMM recipe includes potassium carbonate dosage to adjust pH.

Yes, did temper the rehydrated yeast over a 30 minute period to get withing 10 degree F of the must temperarure.

Yes I also use the potassium as well. I just thought maybe that was one place to double check again. :)

All I have is pH strips and have not had great success testing colored musts with them previously. But, will give it a try next time I I check the SG.

How much yeast did you use?

Your temperature is too low. 65 is the very low end for this yeast. Warm it up!

Better brewing through science!

Used 1 packet of Abbaye yeast.

Thanks LOR. Will turn up the heat in the shop and get the carboy up off the concrete floor.

Before moving the carboy to a slightly warmer climate this morning I checked the S.G. It had decreased 12 points since yesterday to 1.074. The ferment is finally taking off.

This ferment completed a few days ago. Wyeast 1388 can take some abuse and still recover to give a healthy ferment.
