Mangrove Jack's M44

[Alexsson]

Hi,

I have a two questions regarding this yeast (US West Coast (Mangrove Jack's M44)):

(1) Attenuation:

It says it has an attenuation of 4, what does this number tell me in percent? I want to convert this number to percent to be able to approximately estimate the FG.

(2) Number of yeast cells per gram

I want to have the number of cells per gram to use this calculator: http://www.brewersfriend.com/yeast-pitch-rate-and-starter-calculator/.

On the product-side it says:

5 x 10^9 CFU/gram

Is this basically the same as saying 5 billions per gram?

Thanks

its pretty standard from most yeast, what I saw was they are 10 gram packets not 11 like most and anything over 1050 use 2 packets. I normally use one my self up to 1060 else 2 after on any yeast and have had no problems

Ok thank you.

How about the attenuation, can one assume a 80% pre-attenuation?

Attenuation depends on the fermentability of the wort , i've had over 80 with this strain .
Very clean yeast
