American, Irish whiskey. Scottish, Japanese, Canadian whisky. This is not important.

Includes bourbon, rye, Tennessee whiskey, corn whiskey, wheat whiskey; and there are a few American single-malts.

Is an American whiskey distilled from mostly fermented corn (plus a smaller percentage of other grains), and nearly always in a big column still. Despite rumors to the contrary, bourbon can be made anywhere in the US, though most is made in Kentucky. Nearly all of it is aged for more than two years, and that aging is done in new charred oak barrels which impart a ton of flavor (vanilla, coconut) and all of the color to the spirit.

Is made from at least 80% corn. Most of the stuff sold as “moonshine” is perfectly legal unaged corn whiskey.

For all practical purposes, is Jack Daniel’s and George Dickel. These whiskeys are filtered through charcoal either after distillation or after barrel aging, or both. Other than that, they are pretty much bourbon.

Is an American whiskey distilled from mostly fermented rye. It is often a little bit spicy (think of rye bread versus corn bread), and is popular in stirred cocktails like the Sazerac and Manhattan. Rye went out of favor for decades, but is now back in a big way.

Is made in Scotland and aged a minimum of three years. Most scotch ages in recycled casks that previously held American whiskey. A few regional flavor shortcuts: “Islay” usually indicates smoky scotch, “Speyside” indicates soft and supple scotch, “Lowland” scotch is light in flavor, and “Highland” scotch whiskies have a greater variance from robust and earthy to pretty and floral.

Is made at a single distillery from only malted barley (not a blend of grains as in American whiskey) and distilled in pot stills. The age on the label is the age of the youngest scotch in the bottle, though there is often some older stuff mixed in.

(Johnnie Walker, Dewar’s, Famous Grouse, etc.) combines single-malt scotch (usually lots of different ones) with more neutral, column-distilled grain scotch whisky. It is lighter and more subtle than single-malt scotch, and also way more affordable and popular.

Mimics scotch whisky for the most part (the guy who created both Yamazaki and Nikka whiskies trained in Scotland), though they prize their blended whiskies just as much as the single-malts. Blended whiskies in Japan are often served in highballs with soda water.

Is most often a light and easy-drinking blended whisky, usually with flavorings and coloring in the mix. Canadians often refer to their whisky as “rye” but that’s their generic term for whisky rather than an indication of rye grains used.

Includes smoky, neutral-tasting, robust, and single-malt variants, but as Tennessee whiskey’s identity is largely defined by Jack Daniel’s, Irish whiskey’s identity is largely understood from Jameson. Jameson is a blend of lighter grain whiskey with heavier “single-pot still” whiskey, and the result is soft and creamy, and a great introduction to aged spirits for those new to the whiskey category.

It all goes great with ginger ale. If you want to get fancy, make that ginger beer instead, consider a squeeze of lemon or lime, maybe add a dash of Angostura bitters, and garnish with a sprig of mint.
