I've been brewing for about a year now and want to start experimenting with ingredients like fruit, spice, etc. I've done a few blue moon clones and a pumpkin beer but other than that, haven't experimented with these things much. I'd prefer not to put all the time, money, and effort into making an entire batch (or even a half batch) just to make a crappy beer. Have any of you experimented with things before actually brewing a batch of them? Like if I wanted to brew a banana ale, should I just try pureeing a little bit of banana and adding it to the style of beer that I plan on brewing and seeing how it tastes?
