The closest I have come is strawberries in a clean blonde ale, and that all went very well. I plan to start messing with funk soon, and will dedicate a set of equipment to brett/bugs.
I've done a raspberry wheat beer. It came out quite cloudy and took about 8 months for all the flavours to balance. It's quite nice, but I can't really drink more than one in a session. Here 'tis:
Bacchus & Barley Wheat Beer Kit (probably sub in a Morgans kit as they are a bit easier to get)
800g dried wheat malt extract
1kg frozen raspberries blended, seived and simmered with the dried malt extract.
