Lager FG Question

[JamesHoffman]

I made an IPL (recipe details below) and, long story short, my final gravity is way off. I fermented for 17 days at 54°F, did diacetyl rest for 48 hours at 65°F, and just now racked to secondary to bring down to lagering temp (35°F).

Is the final gravity supposed to be this off before lagering? if not, can I bring it back to fermentation temp after I've done the diacetyl rest already? This is my third lager and neither of the previous ones had this problem. I'm confused.

9 lbs Pale Malt (2 Row) US (2.0 SRM)
2 lbs Munich Malt - 20L (20.0 SRM)
1 lbs 8.0 oz Vienna Malt (3.5 SRM)
8.0 oz Caramel/Crystal Malt - 40L (40.0 SRM)

1.00 oz Centennial [10.00 %] - Boil 60.0 min
1.00 oz Chinook [13.00 %] - Boil 30.0 min
4.00 oz Cascade [1.00 %] - Boil 5.0 min

American Lager Yeast (White Labs #WLP840) w/ 1.5L starter

Original Gravity: 1.067
Final Gravity: 1.033 (expected: 1.016)

What IS the FG, taken with a hydrometer (not a refractometer)?

 

[JamesHoffman]

Sorry, I forgot to add that little part. OG was 1.067 and FG was 1.033 (expected was 1.016)

Somethings up there.. 1.033 for FG.. Needs more time to ferment or under pitched (why not a 2L starter / stir plate hopefully/stirred frequently? ) Id set it for another week at ferm temp. and take another FG measurement and go from there.

Just to be sure, you used a hydrometer and not a refractometer?

 

[JamesHoffman]

I keep missing details in this thread. I used a refractometer for the 1.033, I just took a hydrometer sample and got 1.020. thanks for keeping me on my toes

well than thats a big difference. lol 1.020 with expected 1.016 ? Congrats. . . well than . . now rack to keg and store that puppy for a month or more.
