What is the most expensive Moutai ever sold?

Could you elaborate on the most expensive bottle of Moutai liquor that has ever been sold? I'm intrigued to know the specific details of this transaction, such as the year it was sold, the auction house involved, and the final price it fetched. Additionally, I'm curious to know if there are any other notable sales of Moutai that come close to this record price, and what factors contribute to the high demand and value of this premium Chinese liquor.
