Dry yeast-first time

[RyanVTBrew]

I've got a full sachet of safale us-05 from work. I'm brewing today and want to use it. I usually use liquid yeast, and am not sure how much I should pitch. Beers Gravity is 1.055.
Can anyone tell me the yeast to gravity ratio of safale us-05?

dump it in your beer. dump it in 80-100 degree tap water for 30 minutse first if you want to be super fancy schmancy

I have a giant package, I just need to know how much to pitch.

Try this.

Dry yeast is 20 billion cells per gram. If you rehydrate by the manufacturers instructions you'll probably be near 90% viability. If you don't you'll be closer to 75%, and I've seen as low as 50%. (Based on Methane Blue viability staining)

 

[RyanVTBrew]

I ended up pitching a gram of rehydrated yeast. The sachet I got was 500 grams. This sachet will last me for f.u.cking ever.

 

[RyanVTBrew]

Thank you guys, btw.

 

[RyanVTBrew]

Wait, so I should pitch another 9
Grams or so...is this correct?

Did you mean 200 billion cells?

I would keep your giant package away from the beer....

Ah hum, I mean try about 20g.

10g would work but, as would 30g, but I'm gonna stick with 20g.

EDIT- this is based on a 5gal batch and their usual packages being 11.5g and people saying use 2

 

[RyanVTBrew]

Haha, the package says 50-80 grams per hl.
As far as I know 17 hl=15 bbl. So 480 gallons of wort should take 80 grams of yeast. Therefore 5 gallons of wort should take .83 grams?
I'm not sure where I'm messing up here...

 

[ol-hazza]

26 gal / hl according to google, so 2-3 g of yeast / gal.

 

[hopbrad]

How many gallons? A small packet of 11.5 grams is for 5 gallon batches so that should help you decide how much. S-05 is a great yeast

 

[ol-hazza]

TBH im not great at maths though.......

 

[RyanVTBrew]

Oh boy. Ol-hazza, I kind of took your word for it and pitched more yeast.

 

[RyanVTBrew]

Hopbrad, I have 5.5 gallons of wort, with a 500 g sachet of yeast.

 

[ol-hazza]

10-20g and you will be fine provided its the same yeast as what comes in their little packs and the viability is good.

How much have you pitched now?

 

[RyanVTBrew]

I'm at 16 grams now. Pitched one earlier (2 hours ago) read your post and hydrated another 15 grams.

Its going to be just fine.

 

[RyanVTBrew]

I never worry but I'm always curious...thanks a lot for the help brotha!

Just don't ferment it less than 65. Used it for the first time not too long ago on a blonde recipe, at around 62 deg (beer temp, not ambient), and it's got a not so pleasant chemically-peachy flavor that won't go away. 65-67, from what I've read since then, should lead to a cleaner flavor with this strain.
