I suggest you pick a consistent theme as your tasting will be much more enjoyable because your participants can use the theme to pick out differences and commonalities among the spirits in question.
You said:
-Jonny Walker Black Label
-Crown Royal
-Maker's Mark
-Jack Daniels Old #7
-Jim Beam Black
... which makes it very difficult to discern if you have a theme in mind.
Your list includes one blend from Scotland, one Canadian and some whiskeys from the United States. Each has its own peculiarities, which makes it difficult to compare them as you've put out too many variables for a novice tasting effort. Let's take the first one on your list, Johnny Walker Black:
- You are also comparing a whiskey that is blended from distillate from multiple distilleries to US whiskeys that all come from the same distillery.
- You are comparing a whiskey that was aged in second and third use barrels that have previously contained other spriits (e.g. US bourbon barrels), while all the US bourbons are required to be aged in first-use (brand new) barrels.
- You are comparing one whiskey that is distilled twice to some US whiskeys that are only distilled once.
I could go on, but your choices have very little in common except price –– and price doesn't really give you a consistent yardstick in terms of taste. Taste is paramount in a whiskey ... tasting ... and price should take a back seat.
I suggest you pick a theme (with price as a second consideration). You'll be much better off because your guests will actually have something meaningful to discuss, beyond "do I like it?" Why not pick something like "American Bourbons under $40/bottle" so that you'll have less of a wild variation between your tasting candidates?
Example:
- Bulleit
- Jim Beam
- Maker's Mark
- Knob Creek
- Woodford Reserve
All the above are bourbons and have many commonalities, but they also have some subtle differences that can be identified for your guests and they can opine on all of them. As an example, Woodford Reserve is distilled using solely pot stills while the others are usually distilled using column stills (or both). Why not start a discussion as to whether your guests prefer pot still distillate to column still distillate? How about comparing the mashbills of each bourbon and its effect on taste?
Hope this helps!
