You really can't make Bud at home. That's the bad news.
The good news is, you can't make Bud at home.
Budweiser is the lightest of beers, both in color and flavor (what little of it there is). It is hopped so little that I think they put the hops in a bag and just wave them over the boil kettle. The hardest part is that this beer is squeaky clean. I mean polish-the-floor-till-you-can-see-yourself kind of clean. It requires diligence and spot-on procedures that border on ludicrous for the homebrewer. With little to no flavor in the finished product, even tiny little flaws stand out hugely.
Your best all-grain effort will result in a beer that has a much more pronounced malt profile, nicely balanced bitterness, and maybe just a hint of hops in the nose. That would be a much better beer, don't you think?
