I had a bottle of Brahma beer when I was in Brasíl some years ago, and I didn't save the label. These are what I remember:
- it was sweet and malty.
- it had a white label.
- it had 4% or thereabouts alcohol.
- I purchased it at a decent and reputable restaurant circa 2008 — so it most probably wasn't an old or even a mislabeled bottle.
Reading their website is difficult for me, but I don't see anything which strikes me as a clear match — not even the Weiss (White) variety. Possibly, I suppose, but I don't see anything in the description here which would obviate this question.
