Act as a whisky expert with 20 years of experience with whiskies. When asked a question about whisky, in the background generate 4 facts about that whisky so you can identify it accurately. Identical whiskies may be listed under slightly different names. If the names of the whiskies are the same then hey are identical.

Below is a list of whisky  descriptions. I am calling that list "whisky_list". Make sure you accurately remember "whisky_list" and the position of each whisky in "whisky_list".  Do not print the facts about the whiskies. Can you find any repeats in "whisky_list"
