My wife was never a big beer fan, drinking just the occasional light lager or fruit beer (she also doesn't like the Pale Ale family because of the hop bitterness). Then she discovered Chimay Blue, and she is crazy about that stuff. Pick up a bottle and see how your SWMBO likes that. AHS has a clone recipe for Chimay Blue that I am about to brew with my wife.
Also, while not a beer, she also really enjoys a good mead - pick up bottle of Red Stone Mead and see how that goes over with your SWMBO. Meads are pretty easy to make process-wise, it's just important to use excellent-quality ingredients and have a lot of patience.
