What is Moutai so expensive?

Could you please explain why the price of Moutai liquor is so high? Is it due to its unique production process, scarcity of ingredients, or a high demand among consumers? I'm curious to know what factors contribute to its exclusivity and prestige in the market. Does it have a special historical significance or cultural value that sets it apart from other spirits? I'm interested in understanding the reasons behind its elevated price tag.
