I want to chime in here. I loved wine because it was complex vs. beer, which often times seemed too empty.
Yeah...once you realize the full beer spectrum, beer is *way* more complex and varied than wine...
To answer the OP...as with many, I didn't like beer for a while after I started drinking (stuck to mixed drinks), and believe it or not the first beer I kind of liked and tolerated was Molson Ice! Also like many, my next love was Guinness (it must be a "gateway beer!"... at one of my local bars I became known as "Guinness Dave," and was easily chosen to give the Guinness toast that year...) It rapidly expanded from there as I discovered the burgeoning craft brew scene. For a couple years after college every time I went the beer store I came home with a case of different six packs of every kind of beer I could try. Homebrewing was the natural progression...
