Temperature fluctuations - Bad or OK?

(1/2) > >>

gmac:
I'm making an American Farmhouse tomorrow with WLP670 and I don't really have a great way to control temperatures.  I'm normally ferment ales at about 68F in my basement and that temp is quite steady and has never been a problem.
But, I'm trying to decide if this is too cool for this yeast.  My only other option is to ferment this in garage.
A quick check of the 14 day forecast shows an average of about 80 during the day with evening temps dropping to about 62.  Given that it's gonna be in the garage, the highs could be a bit more and the lows a bit less just because it's not sitting outside. 

So, is are these swings an issue with this style of beer?  I use WY3711 but only in the basement, I've never done it warmer and it's been fine but I have no base for comparison either.

I'd say 68* is too high for 3711. If you love fusels though, go nuts.

Huh?
First, this is a question about WLP670.  I've done WY3711 at 68 many time, no fusels that I'm aware of.  Certainly can't taste any, no headaches, no complaints from anyone that's tried it.  Wyeast says 65-77 so I'm at the low end of their range too.  My thought was that in general Saison yeast were better for warmer fermentations.

But the question at hand is "Would WLP670 be better at 68 steady or fluctuating with daily highs and lows?"

tubercle:
From what I read and learned a steady temp is much better for yeast health than extreme swings,

 This is science as Tubercle undersatnds it.

kylekohlmorgen:
Go for the 68f - the garage temps would be rough on the yeast.

Let us know how it turns out - just ordered some 670. Cant wait to try it!
