The upside of drinking good whisky (whiskey)? It's fucking awesome is the upside--& it makes you powerful--even if it does put rattlesnakes in your head (as my buddy Freddie says).
Swiped off the web: (for what that's worth)
1. Irish whiskey is carefully distilled, and produces a clean, refined spirit that matures in the casks into a smooth whiskey. The Irish Whiskey Act of 1980 states that: The spirits have to be distilled in the Republic of Ireland or in Northern Ireland and that the spirits have been matured in wooden casks in a warehouse in the Republic of Ireland or Northern Ireland for a period of no less than 3 years.
2. Scotch Whisky: The principle types of whiskey / whisky are also characteristic of the particular geographical regions of the world. For example the Scotch Whisky Order (1990) and the Scotch Whisky Act (1988) define Scotch whisky. They state that Scotch whisky must be produced at a distillery in Scotland. The word "Scotch" in this definition is of geographical and not generic significance.
3. Bourbon Whiskey: As people emigrated from Ireland and Scotland to the US and Canada they brought with them their distilling skills which were adapted according to the environment and raw materials available to them. These immigrants produced the rye whiskey that became the first "American" whiskey in 1733 (spelt with an e just like Irish whiskey). Bourbon is made from American corn and was originally produced in Bourbon County, Kentucky. Only Bourbon whiskey regulations require that it be matured in a new charred, white oak barrel.
4. Canadian whisky (spelt without an e) is a blend of whiskies most commonly made in column stills from wheat, corn, barley and rye (either singly or combined), and must be aged for a minimum of three years in new wood, bourbon, sherry and brandy barrels.
My favorites:
American Bourbons: I've enjoyed Knob Creek, Bookers, Basil Hayden--& the more typical Jack, Jim, & Maker's Mark. Beware Early Times and Old Crow!
Irish Whisky: Jameson, Bushmills (Black Bush), Redbreast
Scotch--many are very good (& expensive!) I like Lagavulin, Laphroaig, Talisker, Oban
Now I'm thirsty...
