If your mead is good, then your mead is good. Congratulations, kind sir. Nice work. I don't think that ends the discussion, though. The semantic question lies in whether you made it, or someone else did, or helped. The other semantic question is whether you're cheating if you aren't in a game with rules.
I have no objection to someone using all manner of commercial product in a mead, but there is a limit to how much credit you can take for it if someone else took care of the blend of fruits or the degree of sweetness that blend creates. Some competitions frown on that kind of behavior for exactly that reason (don't enter anywhere, and you're not cheating).
The same can be said for any other creative endeavor. It takes some developed knowledge to find sources of truly great bacon. It is another skill and knowledge level entirely to raise pigs and cure your own. You and the guy next to you say you have totally homemade BLT sandwiches. You both made the bread, and grew the lettuce and the tomatoes, but you bought your bacon, and he's a farmer who raised and ground the wheat, raised pigs and made his own bacon (I know people like this - they are "gods" to me). Who wins the truth in advertising comparison here? And for that matter, sitting next to a guy who busts his butt and gets his fingernails dirty in ways it's hard to imagine, it takes some serious hubris to call him a snob.
That level of acknowledgement and obligation to divulge extends to wine - you can't say it is from estate grow fruit if it is not, and you can't say it is estate bottled if it is not. But you can still call it wine. Maybe we need to address those naming delineations in the nascent world of mead.
So your mead has commercial ingredients. That doesn't give anyone license to be rude to you. It's a delicious mead. You just might not be able to enter it into some competitions.
The other thing I will say in defense of the so-called "elitists" is that someone does actually have to grow and harvest and juice the fruit, and create the flavor/acidity/sweetness/tannin blend that is so satisfying. In the wine-making world, there is great and deserved reverence of those people. Grow your own grapes and your hands are brown in the spring and summer, purple in the fall, and frost bitten from pruning in the winter. Equating a mead or wine made with commercial ingredients - and the effort it takes to make it - to one crafted from the ground up is a bit of a slap in their face. Walk a mile in their shoes before you jump to conclusions about who is being insensitive. If perspective is taken into account, and respect is granted on both sides of the table, then both sides can move forward with dignity.
It's like the BLT analogy - the farmer doesn't have license to be rude to you, and you don't have license to call your sandwich "totally homemade." As for me, I may have written a book and may make some decent mead, but I bow down before people like Kirk Jones and Mark Beran who make mead with honey from their own bees. Those guys are bad @$$ed in ways that I simply am not. I'm just another schlep who makes some decent mead with someone else's honey. And likes to write too much.
