Doing an oaked IPA extract kit. Came with 2 packets of dry S-04 yeast. Plan on re-hydrating, wondering if I'm better off using one or both packets?

5 gal batch, 1.068 GG, plan on rehyrdating in 8 oz of water.

How old are they?

I'd say unless they are fairly old, you're fine pitching just one.

It is interesting that the kit came with S-04 and not US-05, though.

Octane IPA kit from Midwest. Did an APA last week with s-05, goign swimmingly, but that was only 1.046 OG. Kit has been at my house for a week. Lord knows how long they had it, they seem reputable, so I wouldn't imagine it's really old stock.

Generally those packets are good for a beer up to 1.05 / 5 gal. SO two makes sense to me, but i've under pitched straight in my nievity and it always worked out so suit yourself.

Calls for 13g of dry yeast, one 11.5g packet should do the trick.

Worst case I could always re-pitch right? Target FG is 1.012-18

I wouldn't worry about it. I used one packet of US-05 to take a 1.100 IIPA down to 1.015. Safale yeast is a beast.

Thanks all. This place rocks. Only my 3rd batch ever, but couldn't have done it without this community.

I've pitched on packet s-04 into 10+ gallons @ 1.06 and it worked just fine for me.

But to be technical, I can read the package here:

http://www.williamsbrewing.com/SAFAL...AST-P1482.aspx

It Says: 11.5g (1 package) good for 20-30 liters (5-7.5 gallons), i'd assume that was with a normal og (1.05), package doesn't say.

Over pitching couldn't hurt, especially if you're not sure it's well oxygenated and all that.

Stuff cost about $3/pack, so not much reason to skimp, IMO.

I'm surprised it says to direct pitch, maybe that's why they recommend using two! Direct pitching can kill up to %50 your viability, so yeah I'd definitely rehydrate it.
