Great idea to have a bit of insight on tasting notes for the Scotches you have available at your restaurant. Have you looked through our Whisky.com directory? See: http://whisky.com/
and look for the 'Find Your Favorite' drop-down box. We have referenced tasting notes for just aboaut all of the brands /vintages you have inquired about. Also, have you looked up these brand web sites? You'll likely find plenty of information there as well.
Also, here is a book I really enjoy - Michael Jackson's Complete Guide to Single Malt Scotch
