Trying to fill my days, and my fermenters with all things beer while I have some time off, my fermentation cabinet is full, but I've got space in my hot closet.

Also wanted to try blending 3711 and 3725, since I happen to have fresh slurry from both yeasts on hand. I really enjoyed the blended 3711 and 3724 I did earlier this year, but I'm itching to try something new. I pitched more 3724 and less 3711, but that's because 3724 tends to poop out early.

This time around I'm using two yeasts that are pretty much monsters, so I figured an equal pitch rate would be a safe bet. Anyone have any experience blending these two, or just blending period?
 
I've blended yeasts on a few batches, but not the yeasts you're talking about. From my experience, blending makes a more complex beer with fuller flavor.

3711 and 3725 would probably taste good together, so I'd say go for it.

Chris White worked with a few breweries who blended yeast. He says in his book that the growth rate for all beer yeast is basically the same, so you won't really have one "out-compete" the other. He does say that when you repitch over multiple generations, you'll get some drift in the yeast ratio. One brewery drifted from 50/50 to 90/10, but didn't notice because they were still getting the same flavor contribution from the lower % yeast.
 
From my experience, 3711 dominates in this blend (not surprising). By the 2nd pitch, I couldn't distinguish it from 3711 alone. In the future I think I'll experiment with pitching 3711 later in the ferment, or growing a much bigger pitch of 3725 so you get more of its flavor.
 
Just to update, the beer came out nicely, but neither yeast seemed to contribute much character, think my temps hovered around 68-70F and muted the yeast contributions.
