Highest gravity for 1 pack of US-05 (5 gallon)??

[Panderson1]

I could have sworn i had 2 packs in my fridge. Anyways , I only have 1. Wort cooling down now. Already transferred to fermenter.

Gravity is 1.065

Normally i would rehydrate 2 packs and pitch.

What do you guys think? Is 1 pack going to stress them out?

The IPA I have now is a 1.068 beer. I just pitched one pack. Didn't even hydrate. I'm gonna keg it next week. Fermentation took off pretty quickly at 72F. I also used US-05.

I don't think there's anything to worry about at 1.065.
I've done many 1.080s with one pack of US-05. Worked great as far as I could taste.
Even so, I'm a big fan of pitching two packs even though I can't prove it helps.

For my OG 65 batches, I sprinkle the equivalent of 1 pack per 5 gal into the wort.

---

• or 50 (to 80) grams per 26.42 gallons
• or 1.9 (to 3.0) grams per gallon

so roughly one pack for a 5 gal wort.

Videos from Fermentis in 2020/2021 suggest pitching more in "high stress" environments (for example: high OG worts and sours). IIRC, OG 65 isn't "high stress".

For the record, on this last batch what I done was......I splashed the wort into the fermenter as it was draining the kettle. Temp of the wort was 75F at the time. When the fermenter was half full, I pitched the yeast and "hydrated" it by splashing the rest of the wort that was emptying the boil kettle. Don't know if you watch David Heath, but that's where I got that idea, so I gave it a try. I saw activity about the same time as I had when doing traditional re-hydrating with boiled/then cooled water.

Well damn. That's good to hear. Thanks. I used to only use liquid yeast and make starters and all. The last 8 batches have come out perfect with 05 and 04. Really starting to love this dry stuff

Edit: so i guess I've been over pitching in my 11 gallon batches. I use between 4 and 5 packs per 11 gallons fully hydrated. Average around 1.068.

Thanks

I would say 1 pack is good for 5-6 gallons to an OG up to about 1.075. You're good with 1 pack.

One pack works fine for ten gallons as well.
Ask me how I know.

Damn lol that sounds crazy. B I t awesome to hear

5 gallon 1.080 i think would be fine higher then that 2 packs

I'm guessing you guys don't worry about aeration either? I know they say it's not necessary with dry yeast. But figured I'd ask in this threads

I've done 6 gallon batches around 1.065-1.070 with 1 packet of '05. Came out fine.

I aerate (old habits die hard), but probably don't need to.

 

[MHBT]

dry yeast is ready to go out of the pack, i ferment in kegs so its easy just to shake the bejezzus out of it so i do, if you wanna repitch it, then you gotta aerate cause it is liquid yeast at that point

That is correct.

 

[Yesfan]

I aerate. Sometimes with O2, sometimes shaking it.

I don't aerate (and I don't re-pitch).

If "they" is the yeast lab, put their knowledge to the test. Take a look at their product information sheets, additional information at their web site ("Tips & Tricks" brochure, Q&A pages, ... ), videos that they post.

If their knowledge helps produce an enjoyable beer, everyone wins.

I oxygenate every time via an inline oxygen stone on the way to the fermenter.
Everything that enters the fermenter is foam.
I typically run 1/2-1 lpm.
Dry, repitch or from a starter, all get the oxygen, it's just a part of my process.
