If you pitch champagne yeast into your wort from the start will it attenuate further than done with an appropriate pitch of standard american ale yeast (say WLP001)?

I think people use champagne yeast to help a stalled ferment or when the alcohol content is getting too high. But I don't think that champagne yeast does a particularly good job on thins like maltose or maltotriose.

But maybe I am wrong.

According to Shea Comfort, no, it doesn't. At least not by itself. It will eat leftover simple sugars that the beer yeast couldn't get to due to a harsh environment, but it will definitely not ferment maltotriose. There are enzymes that you can add that will break the maltotriose down into something that it will consume, but you need to be particularly careful with the amount that you put in, or you will dry the beer out too much.

Another thing to consider is the Kill Factor of the champagne yeast. 12-24 hours after you pitch the champagne yeast, most of your beer yeast will be dead, due to a protein that the wine yeast produces to help outcompete other strains.

did not know about the kill factor... I was thinking about making a banana mead and pitching both champagne yeast and a Belgium ale yeast in an attempt to get the banana esters. Should I maybe pitch the ale yeast first and the champagne yeast a week or so later? –  Germ Jan 28 '11 at 23:36
    
i didn't know how many of the wine yeasts have that until i listened to the show i linked (which i listened to last night... i'm by no means any kind of expert). that would probably work. at least one of the wine yeasts doesn't have a kill factor, though (71B). –  baka Jan 29 '11 at 4:00
