Mixing Lager Yeasts - Pros and Cons
« on: May 17, 2012, 08:16:35 PM »
I have read alot about people mixing lager and ale yeasts together to get the best of both worlds. I have also read that in most cases a dominant yeast will usually lend the most character to the beer.
With that being said, I am conducting an experiment mixing two lager yeasts together. I threw 2 vials into my flask to make a starter - 1 vial WLP833 (German Bock) and 1 vial WLP838 (Southern German Lager). They both look pretty close when complared on White Labs yeast charts. I know that the WLP838 tends to drop out of the beer pretty fast making it pretty clean. The WLP833 tends to be slightly more 'dusty' and doesnt drop out as fast. Other than that - I would say they are pretty close in most respects with the obvious flavor differences.
I really like these two yeasts - alot! Hence the experiment at hand. I pitched the big starter onto an Oktoberfest I like to brew.
Has anyone done this before? What was the outcome? Thanks in advance :)

well, since you asked....my first thought is "why?"  What do you expect to get out if this? My own experience with pitching 2 yeasts at once is that one dominates and you can't tell the other is there.  I've had the best success by pitching each into its own batch and then blending post fermentation.

I think my initial thought was "Why Not?" Just to experiment since the yeasts have many similarities. I am not sure what to expect...and I think that is part of the fun. I have also had great success with both of these yeasts individually, then blended. It might be a huge failure, but there is a chance of success. Besides, if it is gross, it only cost me 5 gallons and a little time.
Could be fun, right?

I really doubt it will be "gross" or a "huge failure".  I just don't think there's anything to be gained.  Other than saying you did it!  ;)

Normally when you blend yeast you are going for the flavor characteristics of one and the attenuation of the other.

Denny & Major, I hear ya. There might be nothing to gain in the end at all. Ehhh, saying that I did it...that doesnt matter either I suppose. I do really like the feedback though. It is always appreciated when seasoned veterans are approachable and active in this community. Cheers to that for sure! Once again - thanks for the replies. It is about a week into fermentation @ 48 degrees, in a couple of weeks I will know the outcome.

For the Bo-Pils I make we use the PU "D" strain on 5 gallons and the "H" strain on 5 gallons. Blend after they are done. This is what PU used to do, now they use one strain.

FWIW, I like both of those strains, especially 838 in an Oktoberfest Marzen.  I have no idea on whether they will "mate" as you proceed with generations going forward, but I would make a few batches to see!  Sounds like an experiment to me... I wish you good luck.

Cheers to trying something.

Haha, they are both pretty knowledgable either way. As for the age thing - it always tends to be in ones mind ;)

So I guess what I am taking is that this could go both ways. Either one yeast will dominate or they might marry up and be a fine yeast. I am also taking away that Denny is old and Major is full of life...and also that both might be covered in salt and pepper.  :P
Time will tell. At any rate it is Friday night, so it is time to eat pizza and drink beer with my wife. Throw more feedback if ya got it. Thanks :)
