Default Anyone know of a ale yeast with low attenuation?

I'm curious if I can keep some sweetness in my beer if I use a yeast that has a low attenuation. Is the attenuation low on a yeast b/c they just leave behind a certain amount of sugar naturally, or is the yeast just not capable of tolerating the alcohol content, leading to more left over sugars?

What sort of gravity would a low attenuation yeast end at? Any suggestions for an ale yeast?

I don't know much about most of the questions you asked, but I do know, vaguely, that yeasts normally attenuate from 70-80% of sugars.

Safale 04 is a low attenuator, as is WLP 002, I believe. Many English ale yeasts, for that matter, are low attenuaters.

Most of time an ale yeast stops when the complexity of the remaining sugars exceeds its ability to process them, although alcohol tolerance can play a part.

WLP002 English, Danstar Windsor, Wyeast 1099 would be the best choices.
Remember one unassailable statistic, as explained by the late, great George Carlin: "Just think of how stupid the average person is, and then realize half of them are even stupider!"

Have a look on the White Labs website, gives a list of the attentuation %. This should only be used as a very rough guide, mind you.
