Oh something flyguy's post made me think of. Most are calibrated at either 60 or 68 F. Check the chart that came with your Hydro, or at 68 it will read 1.00 for the 68 calibration

As for diacetyl, most lager yeasts digest what they produce in the initial fermentation without needing a seperate diacetyl rest. Now the wy 2308 would have needed one had you used that.

What Wyeast says on its website re: the 2124:

Quote:
Benefits from diacetyl rest at 58 F (14 C) for 24 hours after fermentation is complete.
I suppose that "benefits from" isn't the same as "needs a", but regardless, I did give it 24 hours at 58 once fermentation was finished.

Your IIPA, I assume, was a 'big' beer while your lager was of 'normal' gravity? You'll almost always lose some efficiency with a big beer unless you really collect a lot of wort and boil it down. If you lauter both batches with the same amount of sparge then you'll be leaving some sugars in the bigger beer, and hence lower efficiency.

Yeasts do make a difference and lagers tend to be drier. In my lager/ale experiment, the Schwarzbier ended up at 1.010 and the London Black Ale at 1.013.
