This is interesting - How to Identify Yeast Flavors in Beer: Wild Yeast and Bacteria
Great link, I had a read when you posted it the other day, thanks. I had no idea bacteria were ever used deliberately to flavour beer, I thought they only ever spoiled it.
I'm sure I heard once about certain lambics or similar (presumably organic) beers being slightly 'trippy' due to LSD-like chemicals caused by ergot or related moulds, but I dunno if these were meant to be present on the barley before brewing or a contaminant during the brewing process. It's probably bollocks because enough ergot alkaloids to make you trip would also make you very ill.
