I like that Bud character. It's acetaldehyde.
That's a misconception that Mitch Steele debunked quite a while ago. http://hoptripper.com/what-is-quality/
"Acetaldehyde is another flavor that results from fermentation issues, and is present in beer either because the beer hasn’t been aged long enough, or if the yeast health is poor, the yeast cells die and burst, releasing this flavor into the beer. In any event, acetaldehyde is hard flavor to discern at lower levels, and is one of the hardest off-flavors to detect and also fix. There is a common misperception that the green apple ester that some people use to describe Budweiser is acetaldehyde. I’ve heard this from very experienced, knowlegable brewing educators, and it is absolutely wrong. Budweiser has the lowest measured acetaldehyde levels of any major American lager brewer, the green apple ester is something else, and this exemplifies some of the confusion about this off-flavor.
Not to name any names, but there is one lager brewer who operates in this country whose beer has definite acetaldehyde-and I think it’s a characteristic of their yeast strain, because it’s very consistent in their beers. So is this an off-flavor? To them perhaps not, but I find it unpalatable.I believe that aroma is due to low-level ethyl acetate."
