I think it's a bit of both. I have introduced people who mainly drink American lagers and the occational Hacker-Pschorr Weisse to Belgian's with a fine Gueuze, and some just love it and others hate it. I also have known a few fellow beer geeks who hated sour beers, but I run into them a year later and they are sour and funky freaks.To be honest I don't understand the comment about wine drinkers. From my experience I don't know any difference between wine drinkers and beer drinkers when it comes to accepting flavors. If you mean hard core bear drinkers, such as beer geeks, I think they are going to be more accepting of the beer styles, even if they are sour than the wine drinker. If you mean hard core beer drinker, by meaning those who guzzel 12 cans of Busch light in a night, then no, they will not be as accepting of anything other than their Light Lager. Again, with the last statement, Lager encompasses many styles, you can have an Eisbock which is a lager, and is very rich and complex, or a hoppy Bohemian Pilsner, or an American lager. Having a specific disposition to a lager or ale style, in my eyes, will have no bearing on a person's acceptance of a particular flavor profile of a beer.I don't particularly enjoy heffe's. I am not a fan of the clove phenol that is usually promenent in that beer style. However, there are a few heffe's I do like even though as a whole I don't enjoy that flavor characteristic. So ina sense, how recepetive someone is of the brett flavor and aroma, can also have to do with the level at which they are presented it too.In the end, I don't think there is any particular group that would be more receptive than another, just like with all tasting matters, it is very subjective and more an individual taste matter than anything.
