I used the same 2 row count as the original recipe, but 1/2 the flakes corn, and 1 pound of minute rice.
Starter was: 2/3 cup of DME w 4 cups of water w/ 1056 American Ale WYeast. I shook this up for a long time and got a real strong fermentation for the first 4-5 days. I'm not sure if I'm not getting enough O2. I'm thinking about getting a pump to get better O2. Any ideas on why this stopped at 1.016 and not 1.005?
I thought about this some more. Adjuncts don't have a lot in the way of nutrients that yeast need. In an all-malt wort you typically don't need to add nutrient, but when a significant portion isn't malted you could run into metabolic issues for the yeast. If they don't have enough nutrients and trace minerals to do the job, they'll stop early because they simply are no longer to eat any more sugar. There's nothing you can really do at this point, but in the future when using adjuncts you should give them some extra nutrients.
That could be the problem.
