There seems to be some doubt on the interweb as to exactly what type of beer American Weiss was. The Wahls, as you may recall, were quite definite that it was a version of Berliner Weisse:
"American Weiss Beer. This beer is brewed from wheat and barley malt according to methods described for Berliner Weiss Beer.”
"Beer from the Expert's Viewpoint" by Arnold Spencer Wahl and Robert Wahl, 1937, pages 156 - 157.
Some still struggle to believe this and insist it must have been in the Bavarian style. I’m sure they’re wrong. For one thing, when the style emerged in the 19th century, Bavarian Weissbier was incredibly obscure, only produced by a few breweries in the South of Germany. Whereas the North German styles of Weissbier, especially Berliner Weisse, were much better known.
Here’s a slightly more expansive description pf American Weiss Beer from the start of the last century:
"AMERICAN WEISS BEER.
The process of manufacture of this beer may be copied from the German methods. However, the material employed and method of mashing is usually quite different. Wheat malt is sometimes, but not generally, used. Instead, grits are employed to the amount of about 30 per cent, together with pale malt. The grits are treated as usual, the mash is started at about 40° R (122º F.), and temperature raised by addition of grits mash and water to about 58º R. (162º F.). The wort is boiled for a short period (about 30 minutes) with hops from one-half to three-quarters pound per barrel.
Strength of wort about 10 to 12 per cent Balling. For treatment of beer during fermentation, see "Berliner Weiss Beer." Ale yeast should not be employed as is often the case but yeast from a Weiss beer yeast should be obtained in case of need. In America the fermentation is generally conducted in vats instead of casks, in which case the yeast is skimmed off. After fermentation the beer is krausened and filled in bottles. Undoubtedly the American article could be much improved by employing the materials, as well as the mashing method in vogue in German Weiss beer breweries, especially the material, as grits will under no circumstances yield those albuminoids that give Weiss beer its character, as wheat malt does. Certainly there seems no reason why American Weiss beer brewers should not be able to procure a good wheat malt.
Weiss beer in America is sometimes stored, bunged, and fined like lager beer, but a brilliant Weiss beer does not seem to catch the fancy of the consumers, who are accustomed to the cloudy, lively article of Berlin fame."
"American handy-book of the brewing, malting and auxiliary trades" by Wahl and Henius, 1902, page 817.
As we’ve learned recently, German versions of the style haven’t always contained wheat either. Though I’m pretty sure they never included corn grits.
Funnily enough, that mashing method isn’t a million miles away from one from 1837 I’ve just translated. Though the earlier one started cooler. At 10º to 12º Balling, the gravity is about the same as in Berlin in the 19th century. Modern German versions are weaker.
The major differences with German methods are the fermentation in a vat and fining the finished beer. I assume they also artificially carbonated it.
Oh yes, that evidence. It comes from I book I’ve had for a couple of years (in digital form) but never properly looked at. Silly me. It’s got some very handy beer analyses. Including these:

Look at the alcohol content: under 2% ABW, about 2.2% ABV. Not much like the Bavarian style. The low extract tells us that it’s also quite highly attenuated. So we have a low-gravity, low-alcohol, highly-attenuated beer. All characteristics of Berliner Weisse.
There’s that settled.
