Ferm. temp on Beer smith vs White labs

[Rhinocook]

So I've just brewed my first brew with a yeast starter and using Beer Smith software. One thing I noticed is that Beersmith said to ferment at 67 yet on the Whites labs bottle it said 70. Which should I do? Beersmith has all the parameters of my specific system and the beer itself, but White Labs knows their yeast!
Like I said, I made a starter on my stir plate over about 20 hours. Would love to hear some peoples thoughts on this one. It has been 4 days and fermentation seems to have slowed right down.

I don't know which yeast you're using, but I have noticed the instructions on the white lab vials confuse some people. I believe what they say is to hold it at 70 until fermentation begins, but then you can lower it to the appropriate temp, since 70 is on the warm end for most ale yeasts. It's kind of a backwards way to do things, but I think it's supposed to make up for the fact that a single vial without a starter is underpitching in most cases. If you go to the white labs website it should tell you the actual recommended temp range for that yeast.

It's hard to give specific advice without knowing what yeast you're using or what kind of beer you're making but generally you usually want to keep it cooler during the first few days and then a few degrees warmer after fermentation slows down.

The white labs website has the specific details on each yeast strain, while the "generic" instructions on the vial are worthless.

For example, here is the info on one of my go-to yeast strains:
WLP001 CALIFORNIA ALE YEAST
This yeast is famous for its clean flavors, balance and ability to be used in almost any style ale. It accentuates the hop flavors and is extremely versatile.

Attenuation:
73-80% Flocculation:
Medium Optimum Ferment Temp:
68-73°F Alcohol Tolerance:
High

Other strains have far different information, so it's important to check!

In the recipe, edit the fermentation profile and optimize it for the yeast you are using and the fermentation temperature you want. The basic fermentation profile with BeerSmith is meant to be modified to match your preference and process.

That's actually the exact yeast I used for my American IPA! I Have it fermenting at 67. Maybe I should raise it up a bit.
