I've heard that the "biotransformation" of hops that is all the rave right now might also be applicable to coriander and some other spices.
In theory, I think biotransformation is possible. In practice, I think it's a bunch of hype that doesn't actually do much of what they say. But maybe that's just me, always the skeptic until someone hands me a blind triangle experiment, which never ever happens.
Dave, I can assure you biotransformation is real and to me, undesirable.
If anything, your conclusion of "undesirable" has been my tentative conclusion as well. I've been turned off by many of the new and supposedly exciting Bretts and sours and American wilds. I think the Belgians of old know more what the heck they're doing. But, opinions (from me, anyway) don't mean a whole helluva lot either.
