The only data missing from that list is max alcohol potetial.

Thanks Angus, great list.
Now, can anyone tell me in simple english what do they mean by average attenuation? Does that mean that the yeasties will munch say 75% of the sugars for a 75% avg. attenuation?

Ted
 
Ted,

Exactly. In tech speak from White Labs:

"Apparent attenuation percentage is the percentage of sugars that yeast consume. Attenuation varies between different strains. The fermentation conditions and gravity of a particular beer will cause the attenuation to vary, hence each strain of brewers yeast has a characteristic attenuation range. The range for brewers yeast is typically between 65-85%."

The higher the attenuation, the more of the sugars will be converted to CO2 and alcohol.

Angus
 
So then, if you know that your yeast has a 75% attenuation plateau, you can figure out the PABV.

Ted
 
Ted,
You can certainly make an accurate prediction. Keep in mind that attenuation varies not only due to yeast but also based on malt type, mash temps, fermentation temps, etc. Even different brands of extracts have slightly different fermentability ratios.
