Must admit I had language difficulties here. By “alter” do you mean change or make less good Gary?
When I did visit Stockholm beer and whisky festival for the second time on Thursday I did struck lucky and got to taste JD white dog filtered and not filtered. Must say the unfiltered spirit tasted simpler and more neutral than the white dogs I did taste in Kentucky last year. However the filtered one was very different and had lots of nice flavours from the maple charcoal and in the same manners as the Kentucky white dog this was really a nice positive surprise.
Leif, my feeling is that the extensive charcoal leaching treatment removes many of the fusels and other congeners that stay in, and give additional character to, straight bourbon. As Chuck has noted in his book, much of the flavor of JD seems on the surface, I think he wrote you have to "tease out the flavours" and I agree with that. This was of course an intentional result of the Lincoln County process, the idea was to pre-age the drink and render it palatable without years of barrel aging (or other means of rectification).
Today, JD is given, and this has been so presumably for a very long time, at least 4 years of barrel aging too. I wonder if perhaps the earthy/woody notes of JD would be reduced if it was aged only two years. Possibly, but I don't think it would taste better at 2 or 3 years of barrel age. The Green Label shows that a presumably less mature JD - whatever any actual differences in age between the black and green labels - does not (IMO) result in a better palate. In fact, JD is complete after its 4-5 years of aging but, to get back to my main point, in single barrel form you can best appreciate it: it is easier to tease out those flavours, in other words, and they can be quite good.
One of my current two single barrels is excellent, the other is okay. My blend I mentioned is superb and has a marked fruity note, not just banana, but dark fruit, similar in this respect to a Silver Select I had last year and which does not generally obtain with JD. This is what a mingling can do and by the way, JBBL also sometimes acquires that dark fruit note and that is when I like it best.
but then, i will give the gentleman jack a try if ever offered it. for scientific purposes, of course...!
and i do prefer JB's higher end selections over anything by JD distilleries.
but speaking of tennessee, i'll take GD sippin' whiskey anyday over that black label pop culture image!
and over that? give me Wild Turkey 101. any day!
I really enjoyed Gentleman Jack the first time I had it. Definitely smoother and sweeter than their regular No. 7. Tasted to me like apple cider more than anything else, but had a strange, almost salty quality on the tongue that kind of threw me off at first.
I like the Daniels products, always have and keep them on hand. Gary has covered the tasting notes so I won't repeat them here. Oh I don't drink the brand everyday, or ever month for that matter, but its on my list of top five recommendations because it simply is a classic.
