This is a further follow-up re pre-Prohibition Anheuser-Busch gravities. Here it is for Bud (I just found it) in 1884: 1015.
The abv was a touch over 5%, essentially the same as in the news ad I linked about 20 years later.
I estimated 1016 for Bud in my previous post, pretty close.
In this online discussion, homebrewers making a Bud clone estimate 1008 FG and I’ve seen some go lower.
Even assuming Budweiser was 20% rice by 1884, that is a 7 point spread. Of course, 1884 Bud would have been much hoppier, but still. Given too the hops before WW I were advertised as the Czech Saaz – presumably AB used 100% Saaz at least for aroma – it must have been quite a different beer then.
