Well, the barrels are pretty much a non-issue, there being only two cooperages used among the commercial distilleries.
And regardless of what you may hear from PR folks and True Believers, the water actually used in making the whiskey has been conditioned to meet the same uniform GMP standards required of any food-grade process.
And as long as it's #2 yellow and not moldy, it doesn't really matter if the corn comes from the farm next door or from the other side of the country. The barley, wheat, or rye can, and often does, come from other countries. And nobody cares, as long as it meet specs.
Even the production software is standardized and regulation-compliant.
About the only thing that's variable anymore is the yeast.
And there's folks here that will point out that even the yeast used these days is not really as esoteric as it may once have been.
Or is it?
We all know that the integrity of the fermentation is maintained by rigidly controlling the environment in which that occurs. There is, however, a misconception that this is accomplished by (among other factors, of course) ensuring that the distiller's proprietary yeast, and only that yeast, can get access to the goodies in the tank. The fact is, that just isn't so. And you really don't want it to be. As in the real world, there are a variety of yeast strains (families, tribes, ethnic groups, nationalities, races, call them what you will) who set up little territories in the fermenting tank. And like their counterparts in the human world, they "eat" different foods (nutrients in the mash). That has a profound effect on their, uh, well, I'd like to be more delicate here, but I just don't know how to say it any other way, their excretions and their breath. These strains don't always get along real well, either; not unlike their human counterparts. That fermentation vat is a miniature Middle East, just crawling with rapidly-growing civilizations, each trying to eke out a space for its children. Nearly all of these are minority groups, of course. THAT's why the distiller dumps plenty of the signature yeast into the mix, in order that it become the dominant culture. I'll be happy to avoid the obvious political metaphors here as to whether that's such a good idea. Suffice it say that, if left alone, there is a good chance the yeasts indiginous to the area where good whiskey is made are apt to produce some really excellent whiskey. Like they used to. But the mix isn't the same every time and some batches could turn out horrible. When they made it a barrel or two at time that wasn't a big deal, but those who became really successful were those who became really consistent. Some claimed it was the water; other insisted it was their unique recipe. But most agree it was their special yeast.
And it certainly helps to have a good and dependable yeast strain that makes up the bulk of the flavor in your whiskey. But what every distiller knows (and firmly denies has anything to do with anything) is that what makes HIM so special is his ability to gauge just when to add it. Just what temperature to bring, say, half the cornmeal to, and then leave it there awhile, and then you add the rye when the temperature's just right, then the rest of the corn, then the malt. And THEN the yeast. And maybe not all at once, either; maybe some now -- then wait -- then more. And all the while this is going on, wild yeasts, indiginous to the region, are taking hold all over the place. The main yeast will knock most of them out right away, and eventually overpower the rest and dominate the environment. But not before the mash has taken on traces of the unique flavors that each of them provides.
The wild yeasts are everywhere, of course. And barrels of Kentucky whiskey have a knack for finding themselves in warehouses far removed from where they were originally distilled. But the yeasts' relative populations, and their effectiveness in taking hold in a distillery fermenting tank environment, varies considerably within rather small areas. Bourbon from the Franklin/Anderson/Woodford county area tastes different from whiskey made in Jefferson County (Louisville), which, while similar to Owensboro whiskey or Nelson County whiskey, is not exactly the same. This is probably frustrating for distillers like Craig Beam who must try to produce familiar flavors unique to Bardstown with mash he's now fermenting in Louisville. I can picture poor Craig making field trips to Nelson County in search of spoiled berries and other sources of native yeasts to kidnap and bring back to 7th & Breckenridge.
Someday, a hotshot young graduate chemist (who probably drinks flourescent green lime vodka martinis) may come up with a mapping of synthetic yeast flavors that will be capable of slipping through a loophole in the bourbon regulations and allow a distiller to recreate some of the indiginous flavors found along Glenn's Creek, or the Salt River. Or the Monongahela for that matter. Won't that be a wonderful day? But then, it's probably more likely that another young graduate, this one from a law school, will find a way to require distillers to match, without deviation, one of six Federally-approved whiskey flavor profiles and we can then simply depend on the writers of back-labels (and whiskey magazines, of course, except for one red-head I know who would probably quit in disgust instead) to point out the subtle differences that are no longer there and why we should be paying $98 a bottle for it.
I love American whiskey. I'm not ashamed to say I also like soda pop. Coca Cola. Jack Daniel. Pepsi Cola. Woodford Reserve. Royal Crown Cola. Buffalo Trace. Dr. Pepper. Four Roses. Each is highly unique in its flavor. But the soda pop is completely one-dimensional. No undertones; no subtle changing of flavors as one component evaporates faster than the others. Is that the way American whiskey is headed? Simple, instantly-identifiable trade-mark flavors. I hope not, but I'm not optimistic about it.
Gary, I think you're very correct about the regional tastes.
And I think you should try very hard to remember those differences.
Because your grandchildren will probably think you're just telling "how things used to be, back in the day" stories.
