Pitching two different styles of yeast

[Steven9026]

Would pitching two different styles of yeast into your beer create a different flavor? Example mixing Safale S-04 and Safale US-05 together. Would there be any advantages or disadvantages, taste differences etc. ?

Yes. You will get characteristics from both yeasts in the resulting beer. By pitching 04 and 05 you would get some of the estery profile of the 04 and perhaps a bit better attenuation from the 05. It would probably clear pretty well due to British yeast's flocculation habits.

That's not to say that tossing both yeast into the fermentor will give you the same thing as blending two separate 2.5 gal batches fermented with each yeast. The two strains will behave differently in the ferment. Most likely, one strain will be more active than the other and the resulting beer will be skewed towards the yeast that took the headstart.
