Temperature variation of extra pale cream ale

[Riverwalker]

hello everyone, I am sure that this has more than likely been asked in the past, but I was curious about the functionality of yeast in 70-74 degree temperature. We used Dry Ale Yeast Safale US-05. Currently we have two batches fermenting, an Irish stout which calls for the temperature to be within the 70-74 degree area which is perfect, however we are also brewing an extra pale cream ale which calls for a cooler fermenting temperature of ~70 degrees. How will this effect the flavor of the finished product? will the higher temperature quicken the pace of fermentation? Thank you everyone for your help!

Cheers!

Higher temps will lead to faster fermentation, but also more esters and off flavors depending on the type of yeast. An american yeast like s-05 should be less than 70 degrees for best flavor from that type of yeast. Some yeasts like belgian yeasts can go into the 80s and actually benefit from it.
Does that mean your beer wont be right? No. It will just have a different flavor than one made at a lower temp. Make it, drink it, make it again at a lower temp and see what difference it makes..
