I know what you mean, but what does beer taste like? grass? pine trees? juniper berries? bananas? all of those flavors have been part of beer for ever, a good pilsener urquell has strong hints of grass, a good hefeweizen is judged on how well the esters from the yeast impart a banana flavor into the beer. Oyster Stouts have been around since Victorian time, they don't "taste like" oysters, they simply have a hint of a taste that you can pick out on your tongue, the rest is pure "beer flavor". Now more to your point, these new Root Beer Beers to me is garbage, the Radlers. shandy's etc....that is where i am on your side.
Bottom line, as long as YOU enjoy what you are drinking, that is all that matters, but do yourself a favor, every once in a while, step outside your comfort zone and try a new style of beer, not saying you'll like it, but who knows. Forever, the thought of sours repulsed me, now Sours are the latest beer craze, I keep sampling them and more often than not I find myself saying, "Hey, that's not half bad"....beer is fun.
