I made two batches of this, and am not fully happy with either. I keep getting a noticeable sweet after-taste.
In the first batch, I had boosted the gain bill to an even 2 pounds each of flaked maize and 6-row. After I ended up with this sweet aftertaste, I reduced the corn back down to 1.75 pounds for the second batch, while keeping the 2 pounds of 6-row. I also skipped dry-hopping the second batch. While the sweet aftertaste was diminished, it was still present in the second batch.
Both batches did show a reduction in gravity in secondary after addition of the Alpha Amylase Enzyme, finishing around 1.007. I wonder if I either didn't add enough AAE, or if the yeast gave up before the AAE was done working. However, the theory of the yeast giving up has a strike against it since the carbonation was even and as-expected following priming and bottle conditioning.
