I've brewed a simple hefeweizen a couple of times and now swmbo has requested I add fruit. Personally I prefer my fruit in a bowl but I thought I'd brew up a batch and then take a couple of 1 gallon carboys from it. Question is does anyone have any suggestions of what works well with wheat? I'm thinking blueberry but that's the limit of my imagination. Also what's the best way to add fruit? Fresh? Tin? Extract? Any advice would be welcome.
