A group of us at work are planning to have a whiskey tasting. However, I'm limited in my knowledge of what brands from which locations, and we're all kind of narrow
in the brands we've tried before. Also, if anyone has any etiquette suggestions, I am all ears. (or eyes if you want to get technical)

I know the different areas are Speyside, Highland, Islay, Island, Lowland, and Campbeltown. If you have any suggestions as to what brand from each of these
locations and whether to get a blend or single malt, it would give us a place to start. Thanks for the help.
