JohnT - My sister-in-law's husband got one of those while we were helping to build our in-laws place in TN and that's when I first heard about the "belt".  That limestone water may work well in Jack Daniels, but it sure can hurt when it makes a kidney stone.

No limestone water in Jack Daniels.

The water comes from a source deep in the mountain and is tested daily.

100% pure water with no minerals of any kind.

The water quality there is one reason the original still was located on the site it still stands on today.

All ingredients are 100% natural.

And then folks mix it with all that bottled stuff that contains no tellin what.

JUMP BACK JACK has nothin in it that will hurt you.

Might hurt yourself after drinkin it though

JD is the smoothest neat wiskey this old farmer has ever tried. Anybody mixes that needs help.   Trapper

.....5th, I saw a map one time on some health site and it showed it starting in Kentucky and winding its way down through NC/SC and northeast Georgia. The state that should have been basically colored all over was NC with the exception of the Great Smokies. The big deal in NC appeared to be a lot of sulfur which they have an abundance of down east, especially in the Ft. Bragg area. I dated a gal from there long ago and when we went to her family's residences you could smell the sulfur. When you (me) tried to drink their tea I about puked from the odor in the glass. Between the water that was used to wash the glass, the water in the ice and then the tea, it was unbearable. Guess they were used to it. She had a bunch of brothers and sisters and all of them eventually had serious KS problems. JohnT

I stand corrected.  (Okay, I'm sitting.) 

It has always tickled me that Lynchburg is in a dry county.  All of that whiskey coming out of there and you can't buy a drink of it where they make it.  I've never been a big Jack drinker.  Too sweet for me - but I keep it here for friends who like it.

Maybe the water down there is why Southerners are so fond of their "sweet tea" so that the sugar kills the sulfur taste?

a cheap whole house filter does all that most water needs to filter it out. I had my problems with stone here in northern In  but there are time when we have to chew the water under normal situations too but since I put in a whole house filter that is gone now. But instead of the yearly change of filters  have to do so monthly instead is all.

I do know that in the Atlanta are the issue is not so much chemicals as it is organics and then the east around NJ they have the same but out near Seattle they have great water with only light organics whereas here near to Lake Michigan the minerals is the issue--hard water. But the best to plumb with for me has been plastic but I stick with CPVC for the hot side because the others leach chemicals as well.

and as for JD I too stock it for friends but drink my Crown most often and it never gets polluted at all only chilled
