Hosting a tasting

Have any of you ever hosted your own wine, beer or spirit tasting?

Being a big scotch whisky fan, 2 years ago I decided to host my own event for a few friends so that we could all enjoy a few drams and learn a bit about scotch and our tastes.

It has turned into an annual event and this year we may be stepping up the program to some higher quality malts.

I'm looking for any ideas or experiences you have had with your own tastings or ones that you have attended.

Cheers,
Ian
