Mixing US-05 and S-04 in a stout?

[kiwipen]

I was supposed to get 3 packets of S-04 for a stout, but only got 2. I have one packet of US-05. I can just go back to the store and buy one more packet, but how different will the beer be if I just mix them?

I think you'll probably be fine to mix them. US-05 is a fairly clean yeast, so it shouldn't make a huge difference. It will make *some* difference, but you likely wouldn't be able to tell unless you did a side-by-side comparison.

but how different will the beer be

Are you good enough at controlling mash temps and other things to give you the same beer from one brew to the next? If not, then I wouldn't think the difference will be anymore than that. It'll still be decent.

Though if you can easily go and get the other, I would.

Curious why you need 3 packets of dry yeast. What size batch? Expected OG?

 

[kiwipen]

OG 1.072
25 liters/6,6 gallons

I'm using Brewers Friends yeast calculator.

I think you entered something wrong or misunderstand the cell density or something.

Or maybe I do, so disregard. I'm finding other stuff that makes me doubt myself. I'll wait for another to say.

These are 11 gram packets aren't they?

Ugh my buzzed a## switched threads without noticing. Disregard.

Two packs of S04 will be plenty.

Two packs of S04 will be plenty.

That's my thought, too. I can't imagine three is NECESSARY.

That's my thought, too. I can't imagine three is NECESSARY.

I suspect one pack would comfortably get the job done. Two is cheap insurance.

I used two packets of S-04 (dry, not re-hydrated) in a 1.063 OG and it took off like a rocket. 3 does seem like overkill.

 

[kiwipen]

Now you got me doubting the calculator. Should I just use 2 packages?

 

[Rish]

Now you got me doubting the calculator. Should I just use 2 packages?

I did a smoked porter (og 1.072) with one pack of US-05 and it did well. I'd just go with the 2. I think you'll be fine.

Like many others have said... just use two packs.

I've often used two packs of dry yeast on a high gravity beer, never used three, never had an issue.

 

[MaxStout]

2 packs of rehydrated Notty in 5 gallons of 1.090 barleywine, and no problems.

I mostly use liquid yeast, but I have used dry yeast quite a bit as well. I always followed the Brewer's Friend calculator, and I never had an issue. It's very hard to overpitch, especially if you're not rehydrating.

Mixing an American ale strain with an English one is well known to produce fine results, especially in a stout. In fact More Beer used to sell a custom White Labs stain called "Best of Both Worlds." It was a mix of WLP001 and WLP002. I never brewed with it but people who did really loved it. I wouldn't hesitate for a second to mix US05 with 04.

Hundreds of years ago Stouts and all beers would have been fermented with a pitch of mixed yeast strains. That’s just the way it was.

Individual strains of lager and ale yeasts were figured out much later by Jacobsen at Calsberg.

So you are making a historic Stout with the mixed pitch. Brew on!
