I brewed a barleywine at the beginning of January. I fermented in the primary for 3 weeks, and it's currently in the secondary for aging. When I bottle, it will have been in the primary for 3 weeks and in the secondary for about 2 months. I won't be counting on my yeast to be up for carbonating, so I'll be adding back some liquid yeast at bottling time. I did some research and sent my questions over to Wyeast. Here's what they said:
QUESTION:
Hi,
I will be bottle conditioning my high gravity barleywine after aging in
the secondary for 1-2 months. I would like to add yeast at bottling time
to ensure proper carbonation. My questions are:
How much yeast do you recommend using for the bottle conditioning? I've
read 1-2 million cells per mL is a good place to start.
What is the cell density in cells/volume or cells/weight of an Activator
pack (I will be using 1098 if it matters)? What I would calculate is a
volume (or weight) that I need to add to do the conditioning.
In advance, thanks for your help.
RESPONSE:
Thank you for the email.
1-2 million cells per ml. is a good rate for bottle conditioning.
Our cultures are packaged (prior to rupturing the nutrient packet) with
a cell count of 1.2 billion cells per ml. The cultures have a density
of 1.1 g/ml.
You will need ~16-32 ml. (18-35g) yeast per 5 gallons of beer. (3.2-6.4
ml/gal. or 3.5-7 g/gal.).
I hope that this helps.
