This index summarises the overall movement of the secondary whisky market.
"The Whiskystats Whisky Index (WWI) is our major market index. For this index we use 500 bottlings (instead of 100) per month. So this index describes how the overall most traded whiskies changed in value. Since there is no shortage of whiskies traded we additionally imposed one restriction for the WWI. At max 10% of the whiskies forming the index return in each month are allowed to come from the same distillery. For example, the WWI movement of August 2018 was driven by 10% Macallans, 8% Ardbegs and 6% Bruichladdichs."
