From your first post I guessed your duffer pals were snobs. Glad to know I was wrong.
Take your friend up on his offer. Along with an array of single malt whisky (generally five short pours -- you're not there to get hammered) he should offer "palate cleansers." I know that sounds snobby, but it's truly not. Many cheeses, nice hard crackers or breads, and, yes, fine chocolate can accompany a tasting and make the whole session a great pleasure.
For me the chocolate only works well with whisky aged in sherry (or other wine) casks and heavily peated malts.
If he's going to "educate" you, he should know about all the various cask woods and what was in the cask before it was used for whisky (a few distilleries in Scotland use new barrels, but the majority are former U.S. bourbon barrels or Spanish sherry casks.
He should also be able to explain how that smoky or peaty flavor gets into the whisky.
Also note the spelling of Irish, American (most), and Canadian (most) distilled grain products is: whiskey. Scotland seemed to influence the rest of the world to drop the "e" so their products are spelled whisky. Makers Mark bourbon is whisky.
One last thing, then I'll stop, I promise. What's in a name? Single Malt Whisky means the product came from one (a single) distillery, and the contents of the bottle was made with 100% malted barley. Blended Scotch means the products of more than one distillery were used, and in most cases the whisky was made from a combination of corn, rye, wheat, and limited amounts of barley spirits.
