A couple years back, SWMBO would only drink Coors Light and at my request would "try" various craft offerings. Usually coupled with a bitter beer face from a tiny sip and a comment like "Hmmm, thats really strong." After a while if she was really feeling daring she might finish a whole glass of Fat Tire.
I brewed for fifteen years, and this was the same response that I got from my wife. A couple of years ago, my wife and I were traveling in Belgium. It was very hot. We were having lunch at a sidewalk cafe in Brugges, and I ordered a beer ( Leffe, I think) and my wife ordered a Coke. The beer was served from a tap, in a chalice, and it was so cold that you could see the condensation pouring from the entire glass. And here was my wife with a flat, tepid soda in a plastic cup. It was the worst case of beer envy that I've ever seen. I said nothing; just waited for her to notice the irony of the situation. Well, it didn't take long. When the waiter returned for our order, my wife accosted him practically shouting, (like that scene in "When Harry met Sally") "I want what he is having." She loved it. Her fear of flavorful beer melted away, and for the rest of the trip she enjoyed beers she never would have if we were at home.
When we did return to home, she viewed my beer through new eyes. And though she doesn't drink everything that I do, she is no longer afraid to try new beers. And she likes quite a few "good" beers. As a matter of fact, she now prefers my homebrewed beer to anything else.
