Default First IIPA attempt...super high FG?!

Hello everyone,
I started an IIPA on 6/5/11. I let it sit in the primary for 17 days at 68*F before racking to the secondary today. When I measured the gravity I was concerned by how high it was (1.037). It tasted OK (a little on the sweet side of course), but I know it's at least 10 points from where it should be. My recipe is below, as well as the estimated and actual OG and FG.
Would someone please give me some advice? Should I try some amylase and if so how much? Should I try repitching (I've got a package of Notty in the fridge)? Should I just let it be? Help...and thanks!

Possibly a stuck fermentation. I would say that if it is super sweet, it was stuck. I would repitch with more O2 or N2 into the fermenter and get it to 72F. You could use a yeast nutrient. I had ONE beer stuck and I never could get it going again.

Another possibility is that your measurement is not correct. Maybe you have a lot of particulate in the sample? Try to get as much free-floating particulate out of the test.

Default In the same position

I brewed an iipa a few days later than you and it has been stuck around 40 for a few days. I made a starter earlier today,of the same yeast I had washed from earlier batch, and just added it to my primary fermenters and shook 'em. I'm hoping it will do the trick but am not sure if the lack of oxygen will allow them to do their job, but I figure oxygenating it now might end up in a green apple. If you can wait a few days I can convey my results, hoping to see krausen in a few hours.

Call it an american barleywine and drink up. Although 1.037 is a bit high even for a barleywine.

Thanks for the advice beerman. I'm confident that the sample I pulled was relatively clean, so I'm sure the reading is at least accurate to a few points. I'm OK with repitching, but I'm afraid of oxygenating the beer too much at this stage.
What about amylase...anyone?

Thanks steve. Curious - what yeast are you using? Thanks

I am using WLP023 burton ale. I pitched on a yeast cake so I was expecting a huge blowoff. While I did get a blow off it did not last longer than a day or so, which concerns me because the previous batch blew off for much longer. I'm not sure if I under-aerated it or if my attempt to lower the water temperature slightly cause the yeast to flocculate too quick, but either way hoping this new yeast will do the trick.

Pitching on a cake and not getting more activity is a question. I would check your gravity next time on a big beer after blow off has stopped. Then look at rousing the yeast and raising your temps.

That's a big beer. Since it is almost done I would raise the temprature to the low 70s and give it some more time. I would also rouse the yeast to get some back into suspention.
The yeast are drunk and lazy

Getting a huge blowoff is not a requisite for a very active fermentation. It's. A good sign of one, but not getting one is just an anomaly.

My thought is you might have racked too early on a slow, steady ferment, a likely scenario with a second generation yeast, like a yeast cake.

You should think about pitching again with a high ABV tolerant strain that has little character, like a champagne yeast. As to 02, I've never done that.
