That should provide enough oxygen for the remaining work the new yeast has to do.

Just FYI, big beers like this need a LOT of yeast. One BRAND NEW (just made...) pack of WYEAST contains the POTENTIAL for 100 billion cells. A 1.080 beer needs around 540 billion cells...or 5 new packs. So, it would be a great idea to learn and do a yeast starter!
I haven't made a yeast starter yet, but I think I'm going to start from now on. Should I do the standard 2L starter or step it up to 4L?

Every beer will be different and a lot depends on the freshness of the yeast.

Visit Www.yeastcalc.com and you can plug in numbers for each batch you brew and it will calculate the starter size for you to achieve the proper pitch rate as well as any step ups you might need

I'd recommend 4 liters. I have some good starter instructions which I tried to attach for you here but it failed. I'll post a link for you tomorrow. Good luck!

If you have good activity after day 2, I'd let it ride, but that is just me. I do IIPAs that hover around 1.080 and I use two packs of S-05 and I've had no problems hitting my FG within my targeted time.

Was it optimal? Dunno, but it made damn good beer. One thing I learned a long long time ago is don't f**k with it if you don't have to. You start second guessing and adding additional steps and changing things up mid swing you are going to have no idea what worked and what didn't.

Here are the ingredients for the IPA any ideas why the OG came out so high?
7lbs of light dme
1lb Munich malt
1lb crystal 40l malt
30 HBUs of centennial hops added at 60 min
3 oz Cascade ( plan on dry hopping)
1tsp gypsum
1tsp Irish moss

Steeped the grains in three gallons of water. Once water began to boil removed the grains with a strainer. Added malt extract to wort once a boil started I added centennial hops, gypsum, and boiled for 50 min. At 50 min added Irish moss and continued for 10 min. Removed wort chilled to 68F then added wort to two gallons of water in primary topped of to 5 gallons and aerated. Took a gravity reading then pitched yeast. Sealed it up wit an airlock

Its been a long time since I brewed an extract, but I'm not tracking how 7#s of DME can give you an OG over over 1.080 with a 5 gal batch. I'd say you should be sitting around 1.060ish.

EDIT: let her ride, I wouldn't do a thing.

I know I looked at the hydrometer three times because I didn't believe it either. The only thing i can think of is that LHBS gave more DME then what is called for

If it was me in your situation, just let it go. I worked with an awesome phd for years and the greatest thing she ever taught me was: "it is what it is".

Your beer will be fine.

My guess is poor mixture with the top off water, probably gave you an invalid OG. With extract, it's really hard to miss.

I agree with gcdowd...often times the water and wort don't mix well when doing partial boils like this. Now that we know you're true gravity is more likely around 1.051, you may well be ok. So sit tight, let your yeast do it's job, and see what you have in 2 to 3 weeks.

Paulgs3: Dry yeast packs have considerably more cells than liquid yeast, so 2 packs of US-05 would be right on for 1.080. 11.5 gram dry yeast packs contain around 200 billion cells, so 2 packs should be pretty close.
