Now that you've discovered wheat beer, why not try some different ones?
Blue Moon is an American copy of a Belgian-style wheat beer. It's certainly good but not up to the same standard as Hoegaarden (also from Belgium) or some German wheat beers, such as Erdinger or Franziskaner, all of which are widely available in supermarkets. The Co-op also has a lovely own-brand (German-brewed) wheat beer.
They're all different, with Hoegaarden having the sharpest lemony tang to it and the Co-op beer being the smoothest on one's palate.
Remember that wheat beers are usually sold unfiltered (and thus cloudy). You need the cloudy stuff from the bottom of a bottle to give it the full flavour, so it's important to use a glass that matches the bottle size. i.e. if you buy a 500ml bottle but only use a small glass, you'll get none of the flavoursome bits in the first glassful (because they'll still be at the bottom of the bottle) but possibly rather too much in the last glass. So you need to use a large glass and, once you've poured out 90% of the bottle's contents, swirl the bottle around a bit before pouring out the last little bit.
