Oh yes we have, but it isn't all that similar to:
the peppery taste I'd get in liquids that I don't notice so much anymore. It wasn't strong, just a hint.
It's more like putting your face in a bag of freshly ground black peppercorns and inhaling deeply
With heavy flavoring we start at .25% - .3% to get a clearly distinguished black pepper taste. Of course, ymmv.
