Sugar Vs Corn

[LionFishSlayer]

Hello all, I am brand new with 2 runs under my belt. First run was a sugar wash with bread yeast. I was nervous about making cuts so after the first 4oz which was tossed (only a 3.5-4gal batch) I just collected 8oz at a time in separate jars until I hit 30 proof. As far as smell went I honestly couldn't tell much difference in any of them, taste obviously got weaker down the line but none tasted bad. I mixed them all together but the last 3 jars and it tasted great. Separated some and added oak chips to soak a few days and was even better! Tasted like whiskey. Next run was the flaked corn maize with malted barley and turbo yeast. Fermented on the grain. Collected in the same manner and this time there was a definite difference in the last jars, first jar was noticeably stronger with xtra bite and the middle 3 jars seemed the best of the bunch. Which is how I was expecting it to be the first time. On to the question..For me the sugar wash was much better than the corn. the sugar wash was crisp and clean where the corn seemed to have some weird flavors. Does the corn just need to age, did I do something wrong or does it just taste that way? ( I know, like you can taste it) But anybody that does sugar and corn regularly is there that dramatic of a difference?
