Banana Bait

Has anyone actually tried Jens Stolt's fermented banana bait?  See  http://www.stolt.dk/eng/bananabait.htm  .  The photos and text are rather glorious - even by the standards of The Purple Empire... 

Sadly, iris seldoms comes down to feed in the cool, cloudy and showery weather that has dominated most of this season, and only descends rarely this late in the flight season.  If one or two of us are lucky, though, the odd individual may descend from on high in the forecast warm spell that's supposed to start tomorrow. 

Accounts and photos, please, on this blog...
