Do you have the OG bottling? I can't even find pictures of it anymore, but it was a squat 5-6oz bottle (not the 6.3oz nip). I could just be imagining them as well....
No, I didn't even know Kuhnhenn was a thing until after I moved out of Michigan. Found nips on a shelf in Ann Arbor, loved it, bought a ton, and I do mean multiple cases of the 2012 release. I have a bunch of rando meads left, too, including various French Toasts, though I only have one nip left (not one of the exciting flavors, and the old nips are all more or less oxidized). Hell, the flavor I do have, you can still buy off the shelf at some store in Northville, according to a photo another meadery posted a month or so ago showing their own product freshly restocked.
The Kuhnhenn's can't get away with being ****** to people the way Three Floyds can. And they are actually shittier, imho. They put on a really kickass anniversary event about 2 years ago, and I had a killer time, pretty much everything they poured was perfect, the event was really well run, the beers they released were great, then things started to really fall apart after that. They went into a ton of debt opening the production facility and the second restaurant, all while the owner was going through a divorce, which also seemed to have cut into assets. They have been increasingly combative with people asking questions about ingredients, label inconsistencies, etc. They even went so far to put up a weirdly aggressive FAQ at Great Taste of the Midwest, an event they have attended and poured at for at least every year I have gone.
Their mead seems to have gone downhill because they are using less honey per batch to increase margins. I think they can't afford to lose money, and are stressed by running their business on the edge, but are going about the way they treat people who have been with them a long time the entire wrong way. I got to a point where I couldn't make excuses anymore. I haven't offloaded what I have in my cellar, but I pretty much only swing in there if I am with someone who has never been and wants to go. We used to have a ton of fun there, despite the somewhat brusque service. And I like Frank Retell (the meadmaker) quite a bit. The woman who does the wine, whose name escapes me, is also fairly passionate, and if you happen to be in when she is there, she will gladly chat you up about the product. It's the kind of service you expect to see from much smaller places. The whole thing frustrates me and makes me a little sad. Sorry, that was way more answer than you asked for.
