Thanks for the quick response... I have a few more of the "new" bottles. Just gave them a quick rinse, smell and taste--absolutely clean. However, that doesn't mean the bottle conditioning didn't pick something up. It really doesn't taste "infected"; but instead, very dry and way too bitter...

Here's a strange one... brewed 7 gallons of an Old Speckled Hen clone. The batch was split into 2 fermenters, spent 10 days in primary and 1 week in secondary. All beer was then transferred into a 6.5 gallon bottling bucket (contents of both fermenters were mixed into the same bucket)...
