not to be that guy but,
all sour mash is bourbon whiskey but not all bourbon is sour mash

Might wanna fact check yourself amigo.  If it's never been called bourbon, it's not bourbon.  
If you're pointing out that anything made this way could be called bourbon, I guess you're right, but then there are plenty of distilled spirits around the world, aged in charred barrels, that qualify.  Just because the USA passed a resolution in 1964 to prohibit other countries from importing "bourbon" into the USA, doesn't mean it's not the same product.
So that implies that the name itself means something.  Jack Daniels ain't bourbon. Never has been, and I would guess that, since over the decades they have a lot of advertising capital tied up in distinguishing themselves from bourbon, they never will be.

I am one who just cannot drink Jack Daniels. I can drink the Gentleman variety, if that's all that is around.

Sounds like branding vs definition argument. Brand/position it however you want. By definition, it's bourbon, which I believe is Cincydawg's original point.

There are plenty of spirits out there made the same way, that are not the same thing.  CD just brought up one-- Armagnac and Cognac.  Technically they are the same, because they're made in the same way.
But Cognac has never been referred to as Armagnac.  The distinction is regional, which is another example of branding, but it's a distinction nonetheless.

Because there is no overlap. Let's assume there is a well-known genus of French brandy, defined as brandy made in France. We'll get super creative and call it "French Brandy." Makers of Armagnac accept and promote this designation of "French Brandy," while makers of Cognac reject it and promote their more specific designation of "Cognac." Does that mean Cognac is not French Brandy? Of course not.
I grow NuMex 6-4 chile peppers in my back yard. Because I live in Iowa, I cannot sell them as Hatch Chiles, so I create a new category called "Unicorn Peppers." My business booms, and I move to the Hatch Valley to take advantage of a longer growing season. My newly invented category of Unicorn Peppers has gained a lot of traction, so I refuse to market my peppers as Hatch Chiles. But by definition, are my peppers Hatch Chiles? Of course they are.

You're really picking nits in an attempt to prove a stupid and meaningless point.

Jack Daniels hasn't ever been called bourbon.  Except by people attempting to prove stupid and meaningless points.

I'll offer another example.  Gin is vodka.  It happens to include a very specific combination of botanicals including juniper berries, which creates a specific flavor and aromatic profile.  But by definition, gin is vodka.

And yet nobody refers to gin as vodka.  It's never been called vodka.  So it is not vodka.

Jack Daniels sucks.

It's not my favorite bourbon, that's for sure!

There are some differences between Cognac and Armangnac aside from region of original.

Bourbon under US law can only be produced in the US.  Maybe somewhere someone else makes something called bourbon, I don't know.  The basic requirements for bourbon are made in the US, 2 years of aging (at least), and 50+ corn (up to 79% I think) in the mash.  It has an interesting history, including the fact that none is currently made in Bourbon County, KY (though I think someone was building a distillery).

Champagne is the same way in effect, it can only be made in Champagne, but if you look at a bottle of Korbel, you will see on the label "California Champagne".  They were grandfathered in basically.  There are a couple others than can label that way in CA also.

French wines of course are labeled with place names, while US wines are labeled as varietals.  I see more and more French wine labels including the varietal, but you're supposed to know.  I actually know some oenophiles in France who pay no attention to the varietal in a wine.  They know what Bordeaux is, but can't name the five varietals that can be used in it (if it's red) and don't care.

Most know that Burgundy is pinot noir or chardonnay, but they don't know the minors that can be used, and they have no idea what grapes can be used in Champagne.

We were in Costco today and they had some ridiculous prices in Chianti Classico Riserva.  They also had a Burgundy for $10.  I don't know how they get prices down that far other than scale of course.  I'll try the Burgundy tonight.

They have crazy insane wine prices around here.

It's not my favorite bourbon, that's for sure!

hah, you just called it bourbon
