Coopers yeast

[Kev R]

Hi
Anyone know how many cells in a stubby of coopers pale ale?

 

[Moad]

you'll have to culture it up from a bottle, do you have a stir plate and flask?

Probably depends on the age and individual conditions the stubbies been in, I’ve never reactivated the yeast myself but I know of people who say that 3 stubbies worth is plenty, coopers recommend 6 stubbies but they’re using a PET bottle rather than a stir plate which might affect results.
Might have to give this a go on the next brew.

527,642?

If you want a healthy fermentation I’d be stepping up a few stubbies to 250ml then to 2L

Thanks, sediment of 4 stubbies in a 250ml starter of 1030 then up to 2lt at 1030 should get somewhere in the 300 bill. Sound about right?

Make second step 1.04 to give it a bit more to munch on. I reckon that should get you enough for a single batch yep. Not sure exactly about cell count I just go on experience!

I think I did the above with just two stubbies

I've done it using one stubbie without any problems at all.
